B.R. Ambedkar on Caste: Annihilation for Social Unity and Equality

When B.R. Ambedkar stood before a Columbia University seminar in 1916 and called caste a problem still “un-understood,” he was not just describing a social inconvenience. He was setting out to expose the machinery of one of the world’s most durable systems of inequality. Over the next two decades, his thinking sharpened into a radical conclusion: caste could not be reformed, softened, or managed. It had to be destroyed entirely. This is the heart of his vision-the annihilation of caste as the only path to genuine social unity and equality.

How Ambedkar understood caste 🔗

Ambedkar’s understanding of caste was different from most thinkers of his time. He did not see it as a harmless system of occupational specialisation or a quaint cultural tradition. He saw it as a structure of power designed to keep human beings unequal by the accident of birth. His analysis developed across two major works-his early academic paper “Castes in India: Their Mechanism, Genesis and Development” (1916) and his fiery later text “Annihilation of Caste” (1936).

Caste as graded inequality 🔗

The most powerful idea in Ambedkar’s analysis is that caste is a system of graded inequality. This is not a simple two-way split between the privileged and the oppressed. Instead, every caste is ranked in a hierarchy, with Brahmins at the top and Dalits at the bottom. Each group considers itself superior to those below and accepts subordination to those above.

This gradation has a sinister effect. Because almost every group has someone beneath it to feel superior to, the system manufactures consent. The oppressed do not unite against the oppressors, because each layer is busy guarding its own small advantage over the layer below. This is what makes caste so difficult to overthrow-it divides the very people who should be allies in resisting it.

The principle of birth 🔗

Caste status is fixed at birth and cannot be escaped. A person born into a particular caste carries that identity regardless of their wealth, education, or ability. A Brahmin remains a Brahmin even in poverty, while a Dalit cannot shed their assigned position even after achieving success. This is fundamentally different from class systems built on economic standing, where movement up and down is at least possible. In caste, the door is locked from the moment of birth.

The three mechanisms that keep caste alive 🔗

Ambedkar wanted to know not just what caste was, but how it survived for centuries. He identified the machinery that allows it to reproduce itself generation after generation.

Endogamy: the lock on the door 🔗

For Ambedkar, the single most important mechanism was endogamy-the rule that people must marry only within their own caste. In his 1916 paper, he argued that this was the one feature without which caste simply could not exist. As he put it, the creation of caste meant “the superposition of endogamy on exogamy”.

His argument here was striking. India, he pointed out, was originally an exogamous society where marrying within one’s own clan or gotra was actually forbidden. Endogamy was foreign to its people. Caste was therefore created when certain groups-he traced this to the priestly Brahmin class-closed themselves off by enforcing marriage within the group, and other groups imitated this practice to claim similar status. Control whom people marry, Ambedkar reasoned, and you can control everything else.

Maintaining strict endogamy created a practical problem: surplus men and women left unmarried when a spouse died. To keep the caste numerically balanced and sealed off, society developed harsh customs such as child marriage, enforced widowhood, and even sati. Ambedkar noted that these burdens fell most heavily on women, who paid the steepest price for the preservation of caste boundaries.

Division of labourers, not division of labour 🔗

Defenders of caste often argued that it was simply a sensible division of labour, with different groups doing different jobs. Ambedkar dismantled this defence with one of his sharpest distinctions. Caste, he insisted, is not merely a division of labour but a division of labourers.

The difference matters enormously. A healthy society does need different people doing different work. But caste does not just sort tasks-it sorts and grades the people themselves into watertight compartments, ranked one above another. Worse, this division is not based on choice or natural aptitude. As Ambedkar argued, occupations are assigned in advance based on the social status of one’s parents rather than on individual capacity or preference. A person may be forced to starve rather than take up work outside their hereditary occupation. This rigidity, he warned, makes caste a direct cause of inefficiency and unemployment, because workers cannot freely move to where they are needed.

Caste as embedded in religion 🔗

Ambedkar’s most controversial argument was that caste is not an external corruption of Hinduism but is woven into its very fabric. He came to see caste as reinforced by Hindu scriptures and religious belief, which gave inequality a sacred justification. Texts such as the Manusmriti, he argued, legitimised the hierarchy and made the oppression of lower castes appear divinely ordained.

This is why he believed reform from within was hopeless. As long as people genuinely believed the scriptures were holy, they would treat inter-dining and inter-marriage as violations of sacred law. Ambedkar memorably described caste as a notion, a “state of the mind”. It was not a wall of bricks that could be physically pulled down. It lived in people’s beliefs, which meant the fight against it had to be a fight against the ideas that sanctified it.

Ambedkar also catalogued caste’s damage to public life. He argued that each caste behaved like an “anti-social group,” guarding its own interests while shutting others out. The result was a society incapable of fellow-feeling, where charity, public spirit, and shared morality became impossible because virtue itself was caste-bound.

The case for annihilation 🔗

Given all this, Ambedkar refused to settle for gradual reform. If caste was woven into religion, propped up by endogamy, and dressed up as a division of labour, then tinkering at the edges would change nothing. The whole system had to go. This is the meaning of annihilation-not improvement, but complete destruction of the foundations on which caste rests.

Breaking endogamy through inter-caste marriage 🔗

Since endogamy was the lock holding caste in place, Ambedkar saw inter-caste marriage as the key to breaking it. When people from different castes marry and raise children together, the rigid boundaries between groups begin to dissolve. He argued that the fusion of blood across caste lines was the real solvent that could create a sense of kinship strong enough to override caste loyalty. Inter-dining-sharing meals across caste lines-was a step, but Ambedkar believed marriage struck at the root.

Rejecting the scriptures 🔗

Ambedkar concluded that breaking marriage rules alone would not be enough as long as people still revered the texts that justified caste. He therefore called on Hindus to discard the Vedas and Shastras that, in his view, taught neither reason nor morality. This was a demand so radical that the reformist organisation which had invited him to deliver the speech, the Jat-Pat-Todak Mandal, found his views unbearable and cancelled the event. Ambedkar then published the undelivered speech himself, and it became one of the most important political texts of modern India.

Why this still matters 🔗

Ambedkar’s analysis remains strikingly relevant. While overt caste discrimination is illegal today, subtler forms of graded inequality persist through informal networks, social connections, and cultural capital that quietly favour some groups over others. Contemporary debates around the caste census and the sub-categorisation of reservations show that the questions Ambedkar raised about who is ranked where, and why, have never gone away. His insistence that genuine democracy requires social equality-not just political voting rights-continues to shape how India thinks about justice.

His deeper point was about the kind of society worth building. Ambedkar wanted India to be founded on liberty, equality, and fraternity-and he was clear that fraternity, the sense of belonging to one shared community, was impossible as long as caste divided people into ranked and sealed compartments. Annihilating caste, for him, was not an act of destruction for its own sake. It was the precondition for unity.

What do you think? If caste is, as Ambedkar argued, primarily a “state of mind” sustained by belief, can laws and reservations alone dismantle it, or does real change require a transformation in how people think? And in a society where caste identity is still tied to marriage, religion, and social networks, what would the “annihilation of caste” realistically look like today?
