Sex isn’t chromosomes: the story of a century of misconceptions about X & Y

The influence of the XX/XY model of chromosomal sex has been profound over the last century, but it’s founded on faulty premises and responsible for encouraging reductive, essentialist thinking. While the scientific world has moved on, its popular appeal remains.

When the International Astronomical Union (IAU) reclassified Pluto from planet to dwarf planet in 2006, it did nothing to change the fact of the existence of Pluto. Its status, however, is an innocuous example of how science is not always an objective descriptor of reality, but an interpreter, loaded with the context of previous generations – how the Greek “planetai” and the post-Copernican “planets” were both labels to describe things that moved in the heavens, even if we realised those things weren’t actually that similar to each other on closer inspection over time.

The scientific process often involves tweaking taxonomies. Humanity saw distant objects above, and the taxonomy we built was simple: two entries, one labelled “planets”, the other “stars”. Over time we added extra things, like asteroids (rocky) and comets (icy), to cover new discoveries – and, then, even further research (and pictures like those returned by the Rosetta probe) meant that some of the things we thought made asteroids and comets very different were really only a reflection of our perspective. (And, for what it’s worth, at the same meeting in 2006 where the IAU created the new term “dwarf planet” for objects like Pluto and “planet” for, y’know, planets, it also voted to use “small Solar System body” for everything else. This too will pass, probably.) 

We all believe in the existence of comets and asteroids, even though the colloquial distinction between them makes less and less formal sense – would we bother with two different names if we’d only discovered them today? What purpose would drawing the dividing line between them that way serve?

Famously, when the first taxidermied duck-billed platypus was sent back to London by naturalists working in Australia, it was believed to be a hoax, as it refused to cohere to the then-accepted definitions of mammals and birds by insisting on being a hairy warm-blooded creature that laid eggs. The taxonomical status of the platypus (and the few other egg-laying monotremes that have yet to become extinct) is still a subject of debate to this day - biologists have found it has genes usually only present in fish and amphibians. A male platypus even has ten sex chromosomes (XYXYXYXYXY), instead of the normal two for a mammal.

Ah, but there’s a weasel word there: “normal”. And with sex chromosomes, perceptions of “normal” play a huge role – not only in what we think that they are and do, but in the very existence of the term “sex chromosomes”. This is the subject of Sarah Richardson’s revelatory book Sex Itself: The Search for Male and Female in the Human Genome, a history of the science of sex and the invention of the sex chromosome concept – one that Richardson argues we should reject entirely as a mistake that has led to bad science, societal prejudice and widespread misunderstanding of what sex really is.

This is the point in talking about this issue where, so to speak, things can fall apart. Just as mammals not only don’t lay eggs, but shouldn’t, it can come across as a bizarre postmodern self-indulgence to say that humanity isn’t split neatly in two on the basis of whether they’re chromosomally male (XY) or female (XX). This is a framework that makes intuitive sense to almost everyone because it correlates exactly with sexual dimorphism – there are those with penises, and those with vaginas, and with a bit of luck combining the two means we end up with even more humans that each have their own penises or vaginas. But like the platypus, it’s crucial not to think the taxonomy more important than the reality it’s meant to describe.

As Claire Ainsworth writes for Nature, the science of sex has, for some years now, recognised that sexual characteristics exist on a spectrum – not as a binary:

Sex can be much more complicated than it at first seems. According to the simple scenario, the presence or absence of a Y chromosome is what counts: with it, you are male, and without it, you are female. But doctors have long known that some people straddle the boundary – their sex chromosomes say one thing, but their gonads (ovaries or testes) or sexual anatomy say another. Parents of children with these kinds of conditions – known as intersex conditions, or differences or disorders of sex development (DSDs) – often face difficult decisions about whether to bring up their child as a boy or a girl. Some researchers now say that as many as 1 person in 100 has some form of DSD.


Since the 1990s, researchers have identified more than 25 genes involved in DSDs, and next-generation DNA sequencing in the past few years has uncovered a wide range of variations in these genes that have mild effects on individuals, rather than causing DSDs.

Ainsworth’s article is an excellent overview of the current state of the science of sex; Richardson, as a historian and philosopher of science, excels at telling of the people whose work (and whose mistaken assumptions) has misled popular thinking on sex over the years. She describes how existing sex and gender stereotypes were projected onto chromosomes by early researchers, in turn creating and reinforcing the misunderstanding among the wider public that the strict XX/XY binary is a true synecdoche for sexual dimorphism. In reality, there are extremely few sexual characteristics solely controlled by the presence or absence of a Y chromosome – and just as there are plenty of characteristics controlled by genes found on other chromosomes, the “sex” chromosomes also carry genes that determine traits that have nothing to do with sex.

Y is not the essence of masculinity, nor is X that of femininity. As Richardson writes:

Gender has helped to shape the questions that are asked, the theories and models proposed, the research practices employed, and the descriptive language used in the field of sex chromosome research... Today, scientific and popular literature on the sex chromosomes is rich with examples of the gendering of the X and Y. Humorous maps of the X and Y chromosome – pinned up on laboratory walls and always good for a laugh in an otherwise dry scientific talk – assign stereotypical female and male traits to the X and Y, from the ‘Jane Austen appreciation locus’ to ‘channel flipping’.

The X is dubbed the ‘female chromosome’, takes the feminine pronoun ‘she’, and has been described as the ‘big sister’ to ‘her derelict brother that is the Y’ and as the ‘sexy’ chromosome. The X is frequently associated with the mysteriousness and variability of the feminine, as in a 2005 Science article headlined ‘She Moves in Mysterious Ways’ and beginning, ‘The human X chromosome is a study in contradictions’. The X is also described in traditionally gendered terms as the more ‘sociable’, ‘controlling’, ‘conservative’, ‘monotonous’, and ‘motherly’ of the two sex chromosomes. Similarly, the Y is a ‘he’ and ascribed traditional masculine qualities – ‘macho’, ‘active’, ‘clever’, ‘wily’, ‘dominant’, and also ‘degenerate’, ‘lazy’, and ‘hyperactive’.”

We treat the X and Y chromosomes in a way we’d never think of treating other physical characteristics – many people who would think it absurd or rude to tell a stranger that “really you’re male, though” because they have short hair, or a penis, or excess body hair, nevertheless think nothing of doing so when it comes to having XY chromosomes. Sex Itself is the story of how some scientists became convinced that there was something in the body, and then the cell, and then the genome, that would literally be “sex itself” – the only thing that truly mattered for sex, the thing that was its true source and the thing that finally allowed for a simple, causational definition of sex. It’s also the story of how the premise of that entire argument was wrong from the start.

Surprisingly, though, the emergence of the “sex chromosome” concept didn’t happen immediately – while the term itself was first coined by Edmund Wilson of Columbia University in 1906, and not generally accepted by the rest of the science world until the 1920s due to its incompatibility with what was already understood about inheritability.

During the 19th century, biologists were “fascinated by the diversity of forms of sexual dimorphism and intersexuality in nature”, Richardson writes. Sex was seen as something that began before conception and which could change before and after birth – experiments with castrated chickens, and male guinea pigs given ovaries through transplants, gave rise to what was known as the “metabolic model”. A combination of environmental factors – like the health of the parents, or the temperature of an egg – determined the sex development of the offspring.

By the end of the century, though, microscopes had improved enough to allow biologists to see inside the nuclei of cells, and researchers “raced” each other to try and identify the cellular evidence that would confirm the theories put forward by Darwin in On The Origin of Species in 1859. It didn’t take long for chromosomes to be found - but German cytologist Hermann Henking found a weird, unpaired chromosome in the sperm of a fire wasp in 1891. He called it the “X element”, and others speculated that it might be a “degenerate” or “accessory” chromosome that no longer serves a purpose, like the appendix in the human gut.

Between 1903 and 1906, Nettie Stevens (left) at Bryn Mawr College in Pennsylvania investigated this “X element”, and found that it wasn’t alone – there was a tiny Y chromosome hidden right next to it. Elsewhere, Wilson (he who first used the phrase “sex chromosomes”) also found the Y, and agreed with her that its presence seemed to influence the development of male sex characteristics. (Richardson takes some time to sardonically note the extraordinary achievements Stevens, who was never offered a full faculty post, made “in the face of few opportunities for women” – when she applied for post-doctoral funding from the Carnegie Institution in 1903, she “assembled stunning letters of recommendation” from America’s most prestigious cytologists, and “none failed to note her brilliance – for a woman”.)

Stevens and Wilson both agreed that the X and the Y had something to do with sex – but they disagreed as to what. Stevens thought that sex must be one of the traits carried on the X, in the same way other chromosomes seemed to carry multiple traits; Wilson, instead, saw them as solely sex-determing. There was “a whole-chromosome effect – one X kept things titled towards maleness, while two Xs pushed the balance in favour of femaleness”.

The two worked to refute each other until Stevens died in 1912, aged 50. By 1920, Wilson’s version of the chromosomal theory of sex won out, as the term “sex chromosomes” became almost ubiquitous in the scientific literature, displacing “accessory chromosomes”, “hetero-chromosomes” and “idiochromosomes” as popular alternative labels. This came after a strong fight from those who disagreed. Richardson writes of Thomas Montgomery at the University of Philadelphia, who called the sex chromosome theory “an absurd and simplistic overextension of the chromosome theory of heredity”; and of Thomas Hunt Morgan, one of the leading figures in the young field of embryology, who blasted it for inventing “a special element that has the power of turning maleness into femaleness”.

Calling them “sex chromosomes” ran against the accepted convention of naming other chromosomes after their size and structure within a cell, not their function. And there were still unanswered questions: what the hell was going on with species that reproduce with more than two X accessory chromosomes at a time? What about odd numbers of sex chromosomes? A significant number of species didn’t reproduce in line with the neat sex chromosome theory. Wilson was one of those who tried to integrate the sex chromosomes into the metabolic theory – with sex chromosomes, hormones and environmental pressures each influencing how offspring move through different parts of the sex development spectrum – but the damage, Richardson argues, was done.

One of the main reasons the name had such appeal, she argues, is that the 1920s and 30s was when oestrogen and testosterone were first isolated, and the idea of binary “sex hormones” captured the popular imagination:

By the mid-1920s, hormones had become, like genes today, the most prominent object of biomedical, pharmaceutical, and popular interest to emerge from modern biology. Sex hormones seized the public imagination and became a node through which ideas were exchanged between scientific theory and cultural norms, ideologies, and expectations. Scientists promoted the view that the sex glands were the ‘master glands’ of the endocrine system... Pharmaceutical hormone therapies promised new fertility aids and offered the prospect of a simple, highly effective means of birth control. Many also believed hormones would permit the correction of modernity’s gender deviants – feminist spinsters, homosexuals, impotent males, and frigid wives. The endocrinology pioneer Eugen Steinach promoted testicular transplantation as a medical cure for homosexuality and a 'rejuvenation' therapy for low virility and listlessness in elderly men.”

(It was around this time, by the way, that Frank Buckley, the then-manager of Wolverhampton Wanderers, started a rumour that he was injecting his players with a serum taken from monkey glands to improve their performance. The sex hormone fad was weird.)

In this context, sex chromosomes made perfect sense – a matching pair to go with the hormones that determine maleness and femaleness. By the end of the 1930s, the metabolic theory had been discarded in favour of this new model, where the genetic sex (XX/XY) causes the developments of either testes or ovaries, which in turn create the sex hormones that take care of the rest. This two-stage process was “a powerful mutually self-reinforcing framework for the biology of sex”, and the foundation upon which later work – like the idea that sex is biological and fixed, and gender social and malleable - was built.

This can been seen in how the sex chromosomes began to influence debates on gender and sexuality. There was speculation that the Y chromosome “represses” the feminine X, or that femaleness is the “absence” of maleness; or, that the “greater intellectual variability among males” (ie, why male researchers thought men were smarter than women) was down to the lottery of having a single X chromosome. With two Xs, unusual recessive traits would be more commonly repressed, but with one, rare genes presumed responsible for genius must be allowed through. And, similarly, early women's rights activists and feminists, as well as male writers like the anthropologist Ashley Montagu, seized on the idea of having twice as much X as men as the scientific justification for what was really women's “biological superiority” over the male. The idea of the X and Y carrying “sex itself” was entrenched, helped by the fashionable eugenics of the time that saw biology as the justification for a range of racist, sexist and classist prejudices.

This only became worse after the Second World War, with the discoveries of DNA and the first specific chromosomal causes for certain illnesses (like Down’s Syndrome, caused by an extra chromosome 21). The fashion was to think of genetics as the reductive answer to everything – it felt like every physical characteristic, from eye colour to height to intelligence to sex, was caused by the presence or absence of a single gene or set of genes. The sex chromosomes of the 1930s hormonal model – “the genetic homunculi underlying sexual dimorphism”, as Richardson calls them – fit perfectly into this new paradigm.

Karyotypes (pictures of chromosomes against a stark white background) became widely known, giving people perhaps the first real iconic image of the human genome. The sex chromosomes were shoved to the margin or to the end of the last row, accentuating their perceived difference – the format still used today:

Sex Itself has plenty of stories about the general public not understanding that X and Y are not all there is to sex, but it has even more when it comes to scientists leaning on theoretical models built on sand not realising until too late. (Though that isn't to say this was true of everyone – Richardson finds plenty of evidence of geneticists struggling to figure out how much influence they should really ascribe to the X and the Y.)

One particularly damning example is that of the so-called “super male” – the discovery by a researcher that an unusually high number of men incarcerated in an Edinburgh prison had an extra Y chromosome (making them “XYY males”), leading to speculation that “it predisposes its carriers to unusually aggressive behaviour”. The amount of time spent investigating this hypothesis, and its influence on pop culture, is astounding:

The so-called XYY syndrome was a mainstream target of investigation in the most prestigious journals of biology, genetics, and cytogenetics... by 1970, nearly two hundred papers on the link between XYY and aggression had appeared in the scientific literature. Between 1960 and 1970, XYY research comprised 82 per cent of all published scientific studies on the human Y chromosome. It accounts for 28 per cent of the entire body of Y chromosome research generated in the quarter-century between 1960 and 1985.


As Jeremy Green records, ‘by the early 1970s, there had been at least two thriller films in which the main character is a violent criminal driven by a chromosome abnormality, a series of crime novels with an XYY hero (who constantly wrestles with his inner compulsion to commit crimes), and as a spin-off from the novels, a TV series called The XYY Man’. The Oxford English Dictionary cites Peter Cave’s 1974 Dirtiest Picture Postcard as the earliest English-language usage of the Y chromosome in a nonscientific text: ‘You’ve buttonholed me to give me long and boring lectures upon Germaine Greer, the faulty Y chromosome and the drudgeries of housework and child-bearing’.

But of course there was no link between having an extra Y chromosome and extra “maleness”, because maleness is not defined by the Y chromosome. Stereotypically male traits (like aggression, even though not every XYY male in a prison was there because of violent crime) are a result of a complex interplay of nature and nurture, and the projection of the western concept of maleness onto the Y chromosome led to untold hours of research into a dead-end.

And this type of thinking was common with the X chromosome as well - Richardson describes how Klinefelter (XXY) males were seen as more “mother-dependent”, and tested to see if they were more like men or women in their verbal and social skills. XXY males look like men, and most men with the extra chromosome never realise they have it – yet researchers often interpreted their deviations from normal maleness (like larger breasts or smaller testes) not on objective terms, but as “feminised” male traits, in turn creating a stigma.

The last gasp of the sex chromosome theory came in the 1990s, with the discovery of the SRY gene on the Y chromosome – without it, the development of male gonads is impossible. It’s the only genetic tag found only in those who present as male, and is the best candidate to underpin the classic sex chromosome theory. But, as Richardson writes: “Today the SRY gene is understood as one among the many essential mammalian sex-determining factors that are involved in the genetic pathways of both testicular and ovarian determination. Mammals require cascades of gene product in proper dosages and at precise times to produce functioning male and female gonads, and researchers recognize a variety of healthy sexual phenotypes and sex determination pathways in humans.”

Ascribing biological sex based on the presence or absence of the SRY gene makes no sense when it’s only part of a massively complex network of other biological and environmental factors, especially when it’s not even necessary in every species of mammal. (And perhaps we owe our Victorian ancestors some belated recognition here for their more nuanced appreciation of sex development.) Many scientists strenuously argue that research into the genetics of race shouldn’t begin by cataloguing genomes by what we perceive to be different racial groups, to avoid projecting racial bias onto results – shouldn’t we do the same for sex?

Richardson points to several different groups as responsible for digging genetics out of its chromosome-determining rut: criminal psychologists, clinical physicians and, above all, feminists, whose interrogations of gender and sexuality (often from outside the scientific academy) created an important body of empirical evidence. Anne Fausto-Sterling and Jennifer Graves, in particular, as well as feminist science pressure groups like the Society for Women’s Health Research, are cited as important critics of the binary representation of biological or genetic sex - and critical to the post-2000 “conceptual shift” towards the complex model we know today, where the interplay of different genetic and environmental factors gives rise both to physical sex characteristics and aspects of the psychological feeling of gender identity.

Sex Itself is a comprehensive demolition of the very term “sex chromosomes” – a taxonomy from nearly a century ago, stumbling along half-alive in the public’s imagination but long overdue a visit to the glue factory:

Gender ideology is dynamic, persistent, and ever-present in genetic and genomic research on sex and gender; it cannot be surgically or permanently excised from the science. Rather than seeking to somehow eliminate gender in science, we are better advised to focus on modeling the many roles of gender assumptions in particular areas of the sciences to develop gender-critical methods for and approaches to science.

The question is not ‘how can we get all of this gender politics out of genetics?’ but rather ‘how can we enlarge and critically hone our ideas about gender, which are central to our scientific theories of sex?’

In the time between the discovery of Pluto in 1930 and its reclassification as a dwarf planet in 2006, it had only completed a third of a full orbit around the Sun; about the same amount of time sex chromosomes had to enjoy being mystical arbiters of all things sex. Worrying about the hurt feelings of a downgraded planet is as sensible as worrying about those for some clumps of genetic material in a cell – what matters is how we make sure that we interpret our world, and build our taxonomies, in such a way that improves our understanding of the world, not limit it.

Brothers in blood: how Putin has helped Assad tear Syria apart

The Syrian catastrophe has created the worst humanitarian crisis since the end of the Second World War. And the world watches helplessly as Putin and Assad commit war crimes.

Sometimes we know the names. We know Omran Daqneesh, the five-year-old boy who, covered in mud and dust, was pictured on the back seat of an ambulance in the aftermath of an air attack. We know his name because pictures and a video of him were released on social media and travelled around the world. The outrage that followed was widespread and sincere, the image of the dazed little boy seeming to symbolise the greater plight of the beleaguered residents of Aleppo. But then the moment passed. Few will know that a few days later doctors announced that Omran’s elder brother Ali, who was injured in the same air strike, had died from his injuries. He was ten.

Sometimes we know the names of the babies pulled from the rubble of collapsed buildings – occasionally alive, but often dead; or the names of the children weeping over lost parents; or the women grieving over lost husbands and children; or the elderly simply waiting (and sometimes wanting) to die.

We know Bana Alabed, the seven-year-old girl trapped inside Aleppo whose Twitter account has gone viral in recent weeks. “Hi I’m Bana I’m 7 years old girl in Aleppo [sic],” reads the on-page description. “I & my mom want to tell about the bombing here. Thank you.”

A series of pictures depicts Alabed and her mother, Fatemah, struggling to live as normal a life as possible, one showing the little girl sitting at an MDF desk with a book. Behind her, in the corner, is a doll. “Good afternoon from #Aleppo,” says the caption in English. “I’m reading to forget the war.”

The conflict, however, is never far away. Alabed, whose mother taught her English, has repeatedly tweeted her own fears about dying, followed by stoic messages of defiance whenever the immediate threat of an impending air strike passes. On the morning of 3 October, her words were simply: “Hello world we are still alive.” On 17 October, Fatemah tweeted: “The airstrikes ended in the morning, all the last night was raining bombs.”

But in most cases we never know the names of the victims of air assaults led by Presidents Bashar al-Assad and Vladimir Putin. One of the most haunting images to emerge in recent weeks was that of a mother and child, killed while sleeping in the same bed. The scene had an eerily preserved-in-amber feel to it: a snapshot of snatched lives, frozen in the act of dying. Pictures of ruined buildings and distraught civilians have become routine now, holding our attention briefly – if at all.

As many as 500,000 people are believed to have been killed since the beginning of the Syrian uprising in early 2011. According to a report released in February this year by the Syrian Centre for Policy Research, a further 1.9 million have been wounded. Taken together, those figures alone account for 11.5 per cent of Syria’s pre-revolutionary population. Combine that with the number of Syrians who have been displaced – more than ten million (almost 50 per cent of the population) – and the sheer scale of the disaster becomes apparent.

The conflict has become the worst humanitarian crisis since the Second World War. Today it centres on Aleppo, in north-west Syria, one of the oldest continuously inhabited cities in the world, and a cradle of human civilisation. Various conquerors from the Mongols to the French have fought battles there but none, so it would seem, has been quite as ruthless or committed to the city’s annihilation as Bashar al-Assad.

Aleppo remains the most significant urban centre to have been captured by the anti-Assad rebels, most of whom will (by now) be strongly influenced by an Islamist world-view. Indeed, the most prominent fighting groups on the rebel side are overwhelmingly Islamist in their troop composition and beliefs, a sad marker of Western failures to support secular forces that led the anti-regime resistance in the incipient phases of the uprising.

Yet Aleppo remains too important to fail. Although rebel forces succeeded in capturing only half of the city – the western side remained firmly in the control of the regime – the symbolism of anti-Assad forces holding ground in Syria’s second city (which also served as the country’s economic hub) has buoyed the rebel movement.

Assad is more brazen and bullish than at any other point since eastern Aleppo fell into rebel hands in July 2012. That optimism is born of a strategy that has already worked in other parts of the country where the regime’s troops have slowly encircled rebel-held areas and then sealed them off. Nothing can leave, and nothing can enter. Once the ground forces seal off an area, an aerial campaign of barrel bombs and missile attacks from both Syrian and Russian fighter jets inevitably follows.

To get a sense of just how terrible the aerial campaign has been, consider that the United States accused the Russian air force of potential war crimes when a UN aid convoy was bombed just west of Aleppo last month. It was carrying food and medicines when it was hit. Since then, the UK and France have said that Russia’s bombardment of Aleppo amounts to a war crime.

Putin’s support has come as a boon to Assad ever since Russia formally entered the conflict in September 2015. Despite his administration already using Iranian forces and aligned groups such as the Lebanese Shia militia Hezbollah, rebels had continued to make significant gains throughout the early months of 2015. The most important of these was the capture of Idlib city, 40 miles from Aleppo, which presented Assad with two problems. The first was that it dented the official narrative of revanchist military successes by his forces. The ­second was that it handed the rebels power in a province adjoining Latakia Governorate in the west, where Syria’s Alawites are largely concentrated (Russia has an airbase in an area south-east of the city of Latakia). The Alawites are a heterodox Shia sect to which the Assad family belongs, and which forms the core of their support base.

Keen to reverse these gains – and others made elsewhere – Assad enlisted Putin, given Russia’s long-standing interests in, and ties to, Syria. The Kremlin has long regarded Syria as an important ally, and has served as the country’s main arms supplier for the past decade. There are important assets to preserve, too, such as the Russian naval base in the port city of Tartus on the Mediterranean, which was first established during the Soviet era.

For his part, Putin has felt emboldened by events. The world is changing – not just in the Middle East and North Africa, where the
contours of power continue to be recast, but also closer to home in Ukraine, where the pro-Russian president Viktor Yanukovych was overthrown in 2014.

The West is still haunted by the 2003 invasion of Iraq and has been reluctant to be drawn too deeply into the Syrian War. In 2013, the Assad regime used chemical weapons against its own people. This was a violation of President Barack Obama’s so-called red line against the use of chemical weapons, but no retaliatory action came and there was nothing to prevent the Kremlin from using force to shape events in Syria – as it had done in Ukraine.

All of this has marked a new phase of brutality in a conflict already noted for its barbarism. Civilians who avoid death from combined Russo-Syrian air assaults suffer under Assad’s strategy of “starve or submit”, in which supplies are withheld from besieged areas, slowly choking off those ­inside. It has been used to devastating effect against civilians in towns such as Madaya and in Daraya, on the outskirts of Damascus, both of which fell to government control after being sealed off from the outside world for several years. Such a strategy is not designed to deliver quick victories, however. Consider how the residents of Daraya defied Assad’s forces for four years before capitulating in August 2016.

Assad and his allies (Putin, Iran, Hezbollah) have decided to punish and brutalise, deliberately, civilian populations in rebel-held areas. To invert the famous aphorism attributed to Chairman Mao, they hope to dredge the sea in which the revolutionaries swim. And so, it is the 300,000 residents of eastern Aleppo who must suffer now.




It’s easy to lose track of precisely what is happening in the Syrian War as parcels of land swap hands between rebels and the regime. Assad’s forces first began encircling Aleppo at the start of July this year and succeeded in imposing a siege by the middle of that month, after cutting off the last of two rebel-controlled supply routes into the city. The first was the Castello Road, which leads from the town of Handarat into the north-western part of ­rebel-controlled territory. The second route, via the Ramouseh district (which led into the south-western end of the city), had already been sealed off.

The closure lasted for roughly four to five weeks before the rebels re-established access. Aleppo is too important for them, and the siege has forced various groups to work together in breaking it. The effort was led by Jaish al-Fateh (JaF, the “Army of Conquest”), an umbrella group and command structure for several of the most prominent jihadist and Islamist groups operating in northern Syria. JaF also co-ordinated the Idlib military campaigns. One of its key members is Jabhat Fateh al-Sham (JFS, “the Syrian Conquest Front”), which was previously known as Jabhat al-Nusra (JaN or “the Supporters’ Front”) and was recognised as al-Qaeda’s official chapter in Syria.

Several months before the regime began its assault on Aleppo, rebel groups in the north recognised the deteriorating situation there, stemming principally from Russian air strikes. As a result, al-Qaeda urged the various factions to merge and work together to counteract not just Assad, but also Putin. Even the global leader of al-Qaeda, Ayman al-Zawahiri, issued a speech last May titled “Go Forth to Syria”, in which he called on all fighting groups to unite in order to consolidate their control across the north. This opened the way at the end of July for Jabhat al-Nusra to declare that it was formally severing its links with al-Qaeda. It “rebranded” as Jabhat Fateh al-Sham.

There are two reasons for doing this. The first is to erode partisanship among the Islamist groups, forcing them to set aside differences and narrow their ambitions in favour of the greater goal – in this case, the breaking of the siege of Aleppo, while also deepening rebel control across the north. The second aim of rebranding is to win popular support by portraying themselves as fighting in the service of ordinary civilians.

Groups such as JFS and others are succeeding in both of these goals. Responding to the abandoned and assaulted residents of Aleppo, they have repeatedly demonstrated their commitment to alleviating the humanitarian crisis. Much of their messaging echoes this theme. The group’s English-language spokesman is Mostafa Mahamed, an Egyptian who previously lived in Australia. “[JFS] is deeply embedded in society, made up from the average Syrian people,” he explained on Twitter, after the group decoupled from al-Qaeda. “We will gladly lay down our lives before being forced into a situation that does not serve the people we are fighting for . . . jihad today is bigger than us, bigger than our differences.”

It is indisputable that this ethos of “fighting for the people” has endeared the group to civilians living in besieged areas – even when those civilians don’t necessarily agree with the full spectrum of its religious beliefs or political positions. That goodwill was only reinforced when the group helped break the siege of Aleppo (in which approximately 500 rebels were killed) in August, if only for a few days. Assad reasserted control within a week, and entrapped the residents again in the middle of that month. The rebels are now planning how to break the siege decisively, but have not yet launched a major counteroffensive.




A freelance American journalist and film-maker, Bilal Abdul Kareem, who has reported on rebel movements inside Syria more intimately than most, has found himself among those trapped inside eastern Aleppo since the siege was restored seven weeks ago. “We came here expecting a two- or three-day trip,” he told me during an interview over Skype.

Life inside is becoming insufferable for civilians, Abdul Kareem said; every building is potted and scarred by shrapnel damage. Those whose homes remain standing are the lucky ones. “Your day consists of nothing,” he said. “There’s no work, there’s no fuel, no industrial zone, no food to sell. ­People sit around and chit-chat, drink tea, and that’s all they do.”

Food supplies are already running low, with most people limiting themselves to basics of chickpeas and groats – crushed grains such as oats or wheat. Sealed off from the rest of the world, those inside preoccupy themselves with survival and wait for the next wave of attacks.

It is tempting to ask why the inhabitants of Aleppo did not flee when they had the chance. Indeed, the Assad regime routinely accuses the rebels of preventing civilians from leaving besieged areas, though there is no evidence to support this view. On 17 October Russia and the Syrian regime said they would halt their bombardment for eight hours on 20 October to allow rebels and civilians to evacuate the city.

In truth, what choice do the civilians have? Most do not trust Assad and they are therefore unwilling to move into regime-administered areas. The alternative is to become refugees, with all the uncertainties and trials associated with that. For instance, refugees have found themselves subject to sectarian violence in Lebanon, and they have few opportunities to find employment in Lebanon, Turkey or Jordan, the three countries where most of the fleeing Syrians have found shelter.

For them, merely to exist in rebel territory is an act of defiance, which is precisely why Assad’s forces make no effort to distinguish between combatants and civilians in rebel areas. To be present is a crime.

The effects of this have been devastating. A spokesman for the Syrian American Medical Society told Middle East Eye, an online news portal, that in July, Syrian and Russian jets had hit medical facilities in rebel-held territory every 17 hours.

Only a few hospitals and medical staff remain. The physical conditions are primitive and perilous. Doctors work in makeshift facilities – a former flat, a commercial garage – which makes them unable to provide anything beyond basic emergency care. In-patient facilities are non-existent, not just because of high demand from those newly injured in fresh attacks, but also from fear that the facility itself will be targeted. “People are literally shuffled out of the hospital with IV [intravenous drips] in their arms,” Abdul Kareem says.

The West’s indifference to all this – coupled with its occasional pious pronouncements and diplomatic dithering – has squandered any goodwill Washington might once have had among Syria’s beleaguered civilians. When Sergey Lavrov, Russia’s foreign minister, and John Kerry, the US secretary of state, agreed a ceasefire in September it lasted barely two days because they overlooked the fears of those trapped inside eastern Aleppo.

The deal had stated that no party would try to capture any new territory. That might seem reasonable enough but given that the ceasefire came into effect just days after Assad re-established the siege of Aleppo, those on the inside were being asked, in effect, to acquiesce to their own starvation.

Deprived of food and medication, no one trusted Assad to negotiate access in good faith, especially after he thwarted UN efforts to deliver aid. “People saw it as a conspiracy,” Abdul Kareem told me. Moreover, there were no significant groups inside eastern Aleppo that claimed to have accepted the terms of the ceasefire in the first place. Kerry had negotiated on their behalf without approval and without securing any humanitarian concessions.

“What planet are these people on?” Abdul Kareem asked. “[Do] they think people will turn on their protectors, for people who didn’t do them any good? They look to JFS and Ahrar [Ahrar al-Sham is one of the Islamist groups fighting in JAF]. Western intervention is pie in the sky.”

The rise of these reactionary rebels is a direct result of liberal elements not being strongly supported at any stage in the conflict. Left to fend for themselves, many have deserted their cause. Those who have persisted not only risk the constant threat of being killed by Russo-Syrian bombs, but are also at threat from jihadist elements operating in rebel areas. That much was clear when remnants of the secular opposition protested against the leader of JFS, Abu Mohammed al-Golani, in the southern Idlib town of Maarat al-Nouman earlier this year. Many of those who did were arrested by jihadists and intimidated into silence.

Whereas liberals are fragmented and frayed, the Islamist rebels continue to coalesce into an ever more coherent unit. The overwhelming might of Russian airpower has convinced them of the need to form a united front in order to pool their resources and co-ordinate their efforts. That is one of the reasons why a jihadist group called Jund al-Aqsa (“Soldiers of al-Aqsa”) announced early this month that it was disbanding and being absorbed into JFS.

Herein lies the real story of how Aleppo – and, indeed, Syria itself – has been delivered to the jihadists. A conspiracy of all the external parties has forged a menacing millenarian movement that is embedded in civil society and communities across the north. Whether Aleppo falls or not, the jihadists will endure.
