Who Were the Shudras? The Short Answer

In his 1946 book Who Were the Shudras?, Dr. B.R. Ambedkar argued that the Shudras were originally an Aryan people who ranked as Kshatriyas, the warrior-ruler class. After a long conflict with Brahmins, they were denied Upanayana, the sacred-thread initiation, and pushed down to the fourth and lowest varna. The book rejects the older idea that Shudras were a separate race, or the original inhabitants of India conquered by Aryan invaders.

Why Ambedkar Wrote the Book

Ambedkar says plainly who the book is for: “the ignorant and the uninformed Shudras, who do not know how they came to be what they are.” He believed only the Shudras themselves could end the four-varna system, writing that “only the Shudras can destroy the Chaturvarnya.”

He gives a scale to the problem too. Leaving out the Untouchables, he writes that Shudras make up “about 75 to 80 per cent of the population of Hindus.” This is not a story about a small group. It is about most of Hindu society.

In the preface he sorts Hindu readers into five types: the orthodox, who accept the old order; Arya Samajists, who want to reform it from inside; those who think caste is already dying out on its own; the politically minded, who argue independence from British rule matters more than social reform; and rationalist reformers, who want change now. He calls this last group his “mainstay.”

He also describes the backlash he faced. After a speech in Madras, he says he received “a shower of letters… full of dire threats to my life.” He answers this with a line from the Sanskrit poet Bhavabhuti: “Time is infinite and earth is vast, some day there will be born a man who will appreciate what I have said.”

Ambedkar’s theory in six points

The preface states his argument as six numbered points:

The Shudras were one of the Aryan communities of the Solar race.
Aryan society once had only three varnas: Brahmins, Kshatriyas and Vaishyas.
The Shudras did not form a separate varna. They were part of the Kshatriya varna.
There was a long-running feud between Shudra kings and Brahmins, in which Brahmins suffered various insults and mistreatment.
Out of the hatred this feud created, Brahmins refused to perform Upanayana for the Shudras.
Without Upanayana, the Shudras who had been Kshatriyas lost social standing, fell below the Vaishyas, and became the fourth varna.

One detail many summaries miss: Ambedkar does not say today’s OBC castes are “really Kshatriyas.” He is careful to say that present-day Shudras are not descended from the original Shudra tribe. He writes that they “are a collection of castes drawn from heterogeneous stocks and are racially different from the original Shudras.” Over time, he argues, “Shudra” stopped naming one community and became a general label for low-ranked people, so a penal code written for one ancient group ended up applied to many others later, what he calls “this massacre of the innocents.”

The Brahmanic Theory of Shudra Origin

Before giving his own answer, Ambedkar lays out the traditional explanation for where Shudras came from, then shows why he thinks it fails.

The most quoted source is the Purusha Sukta, a hymn in the Rig Veda (10.90). It describes the gods sacrificing a cosmic being, Purusha, to create the world. Four social groups come out of four body parts: the Brahmin from the mouth, the Rajanya (later called Kshatriya) from the arms, the Vaishya from the thighs, and the Shudra from the feet.

Ambedkar does not treat this as a harmless creation story. He argues it did five things at once: it took an existing social order and made it look sacred; it gave that order the force of religious law; it made class itself a matter of divine design; it fixed the number of classes at four, when Romans had only two and the old Indo-Iranians had three; and it set a fixed ranking, which he describes as running from top to bottom in “an ascending scale of reverence and a descending scale of contempt.”

He then checks this story against other Brahmanical texts, the Yajur Veda, the Atharva Veda, the Shatapatha Brahmana, the Taittiriya Brahmana, and later the epics and Puranas, and finds they disagree with each other. Some credit the varnas to Purusha, some to Prajapati, some to Brahma, and the number of varnas shifts between two, three and four depending on the text. His verdict is blunt: these accounts are “imagination running riot. There is in them neither history nor sense.” He borrows a harsher line from the scholar Max Muller to describe some of this material as “twaddles of idiots and ravings of madmen.”

This is the theory Ambedkar spends the first half of the book taking apart, before building his own explanation in the second half.

Chapter-wise Summary: Part I (Chapters 1-6)

Who were the shudras chapter wise summary.

Part I states the problem and clears away the existing theories before Ambedkar gives his own.

Chapter I: The Riddle of the Shudras. Ambedkar opens with the Purusha Sukta and argues it turned a social order into sacred law. The real puzzle, he says, is this: Shudras are counted inside the four-varna system, yet treated like outsiders because they are denied Upanayana, the same way Untouchables are. Why does a group that is formally “in” the system get treated like it is “out”?

Chapter II: The Brahmanic Theory of the Origin of the Shudras. He collects every Brahmanical creation story for the varnas and shows they contradict each other on basic points, including how many varnas there originally were.

Chapter III: The Brahmanic Theory of the Status of the Shudras. He lists the legal and social restrictions later lawbooks placed on Shudras: barred from studying the Vedas, from holding property or office, given harsher punishments, and treated as permanently impure and last in rank.

Chapter IV: Shudras Versus Aryans. He takes on the old “Western theory” that fair-skinned Aryan invaders conquered dark-skinned natives and turned them into Shudras. He argues the Vedas show no evidence of a race called “Aryan” or of any invasion, and that the Rig Veda’s Aryan-versus-Dasa distinction was not about race at all.

Chapter V: Aryans Against Aryans. He argues the real conflict in Vedic texts was between two different Aryan groups, not between an invading race and a native one. He points to verses where the god Indra fights against both Dasas and Aryas on the same side of a battle.

Chapter VI: Shudras and Dasas. He separates the Shudras from the Dasas and Dasyus, arguing the Aryan-Dasa divide was about religion and ritual practice, not ethnicity. This removes the last support for the idea that Dasas became Shudras through conquest.

Chapter-wise Summary: Part II (Chapters 7-12)

Part II builds Ambedkar’s own theory, piece by piece.

Chapter VII: The Shudras Were Kshatriyas. This is the core chapter. Ambedkar makes three claims: the Shudras were Aryans, they were Kshatriyas, and some of the most powerful ancient kings were Shudras. His main evidence is a passage in the Mahabharata’s Shanti Parva describing “the Shudra Paijavana” performing a grand sacrifice with Brahmin priests. Using the ancient dictionary Nirukta, he links “Paijavana” to Sudas, the well-known Rig Vedic king who won the Battle of the Ten Kings. He also points out how unstable varna labels could be in practice, noting that one branch of Kayasthas was ranked as Kshatriya while another, in Bengal, was ranked as Shudra.

Chapter VIII: The Number of Varnas, Three or Four? He argues that the earliest Vedic texts describe only three varnas. The Purusha Sukta, which introduces the fourth, is missing from some early Vedic collections, which suggests it was added later. If so, the fourth varna was carved out of part of the existing Kshatriya group.

Chapter IX: Brahmins Versus Shudras. He gathers stories of conflict between kings and Brahmin priests, especially the rivalry between the sages Vasishtha and Vishvamitra around King Sudas, and reads these as episodes in a longer feud between Brahmins and the Shudra line of Kshatriyas.

Chapter X: The Degradation of the Shudras. He asks directly: what method did Brahmins use to push the Shudras down from second rank to fourth? His answer is the denial of Upanayana. Since only Brahmins could perform this rite, refusing it cut the Shudras off from Vedic learning, sacrifice, and the social standing that came with “twice-born” status.

Chapter XI: The Story of Reconciliation. He answers an obvious objection: how could conflicts between individual kings and priests degrade an entire class? His answer is that the feud was not really personal. The whole Brahmin community and an entire line of kings were involved over time, so the punishment, once applied, stuck to the whole group.

Chapter XII: The Theory in the Crucible. He tests his theory against the evidence one more time: Shudras appear inside the varna system yet barred from Upanayana; some texts describe Shudras as kings and wealthy men; a few texts even hint at a right to Upanayana for some Shudras. He concludes his theory explains these contradictions better than any rival account.

Were the Shudras Kshatriyas? The Evidence and the Debate

The Paijavana-Sudas evidence

Ambedkar’s case rests heavily on one passage. In the Mahabharata’s Shanti Parva, around verses 38-40 of Adhyaya 60, “the Shudra Paijavana” is described performing a major sacrifice and giving large gifts to Brahmin priests. On its own, this is a strange detail: a Shudra acting like a powerful, wealthy king.

Ambedkar connects this figure to a name familiar from the Rig Veda. The ancient Sanskrit dictionary Nirukta, by Yaska, states that “Vishvamitra was the purohita of Sudas, the son of Pijavana.” “Paijavana” simply means “son of Pijavana,” so Paijavana and Sudas are the same person. Sudas is a well-known figure in the Rig Veda: the king who won the Battle of the Ten Kings with help from the sage Vasishtha. Ambedkar also traces a genealogy connecting Sudas to Ikshvaku, placing him in the Solar line of kings. He thanks the unknown author of this Mahabharata chapter directly, writing that “without it, this book could not have been written.”

How Upanayana denial explains the fourth varna

If Shudras were Kshatriyas, how did they end up ranked below even the Vaishyas? Ambedkar’s answer is Upanayana, the sacred-thread ceremony that marked a boy’s formal entry into Vedic learning and “twice-born” status. Only Brahmins could perform this rite. He argues that once Brahmins refused to perform it for the Shudra line, out of anger built up over a long conflict, that group lost access to education, ritual and the status that came with them, and sank below the Vaishyas over time.

Ambedkar and the Aryan invasion theory

Separately from the Kshatriya argument, Ambedkar takes on a different and once-popular idea: that a fair-skinned “Aryan race” invaded India and turned the darker native population into Shudras. He argues the Vedas give no evidence of any such invasion and no evidence of “Aryan” as a race at all. One example he uses is a Rig Vedic word, “anas,” which earlier Western scholars such as Max Muller read as “noseless,” taken as a racial description. Ambedkar follows the older commentator Sayana instead, who reads it as “without speech,” meaning a different language rather than a different face. His conclusion is direct: “the theory of the Aryan race set up by Western writers falls to the ground at every point.”

This part of his argument has aged better than the Kshatriya thesis. Writing decades later, the scholar Arvind Sharma credited Ambedkar with being “far ahead of his times” on reading “Aryan” as a cultural and linguistic label rather than a race, calling it a reading that has since won “approval in modern Indology.” Keep this distinction in mind: rejecting the race theory of “Aryan” and the Shudras-were-Kshatriyas claim are two separate arguments in the book, and later scholars have not judged them the same way (more in the Criticism section below).

The Primary Texts, Explained Simply

Ambedkar builds his case out of short Sanskrit passages, most of them centuries old and carrying unfamiliar names. Here is what the key ones actually say, and what he does with each.

Text	What it says	What it means	How Ambedkar uses it
Rig Veda 10.90 (Purusha Sukta)	The Brahmin comes from the mouth of the cosmic being Purusha, the Rajanya (Kshatriya) from the arms, the Vaishya from the thighs, the Shudra from the feet.	A hymn turns four social ranks into a story of divine creation.	He argues this is the only Rig Vedic verse naming the Shudra, that it is missing from some early Vedic texts, and that it was likely added later to make an existing order look sacred.
Taittiriya Samhita 7.1.1.4	The Shudra and the horse both come from the feet of Prajapati; the Shudra cannot take part in sacrifice.	A different, even less flattering, origin story pairing Shudras with animals.	One more example of how these creation stories disagree with each other.
Taittiriya Brahmana	The Brahmin caste comes from the gods; the Shudra comes from the demons, or from nothing at all.	Shudras are given the worst possible origin, worse even than the Vaishyas.	Further proof the stories are hostile and inconsistent rather than historical.
Aitareya Brahmana 7.29.4	The Shudra is “a servant of another.”	His entire identity, in this text, is service to others.	Shows where the later legal restrictions on Shudras began.
Apastamba and Vasishtha Dharma Sutras	Each caste outranks the one below it by birth; Upanayana and Vedic study are for the three upper castes only, not Shudras; the upper three are “twice-born.”	Rank is fixed by birth, and Shudras are shut out of education and formal religious life.	This is the legal source of the “riddle” Ambedkar opens the book with: Shudras are inside the varna system but treated as outsiders.
Manusmriti 1.31, 10.4, 1.91	Restates the Purusha Sukta as law; says the Shudra “has only one birth”; says a Shudra’s only duty is “ungrudging service” to the other three castes.	The most famous lawbook turns the old hymn into formal, detailed rules.	Ambedkar calls Manu the figure who gave the four-varna system “divinity and infallibility.”
Manusmriti 8.413-417, 10.129	A Brahmin may take a Shudra’s property; a Shudra “possesses nothing as his own”; a wealthy Shudra “gives pain to Brahmins.”	Shudras are denied the right to build wealth or hold property securely.	Shows the restrictions were economic, not only religious.
Manusmriti 10.43-44	Lists several known Kshatriya peoples who “gradually sank to the state of Shudras” after losing contact with Brahmin priests and neglecting Vedic rites.	Even this lawbook admits Kshatriyas could fall to Shudra rank over time.	Ambedkar treats this as support for his own theory: rank could change, and a group could fall from Kshatriya to Shudra status.
Mahabharata, Shanti Parva 60	Describes “the Shudra Paijavana” holding a great sacrifice and giving rich gifts to Brahmin priests.	A Shudra acting exactly like a powerful, wealthy king.	The single most important piece of evidence in the whole book.
Yaska’s Nirukta 2.24	States that the sage Vishvamitra served as priest to “Sudas, the son of Pijavana.”	Confirms that “Paijavana” and “Sudas” refer to the same person.	The link that lets Ambedkar connect the Mahabharata’s Shudra Paijavana to the famous Rig Vedic king Sudas.

A short glossary: Varna is one of the four ranked classes described in these texts. Jati is an actual, real-world caste group, a different and more local idea than varna. Chaturvarnya means the whole four-varna system together. Upanayana is the sacred-thread ceremony marking entry into Vedic learning. Savarna means inside the four-varna system; avarna means outside it, such as the Untouchables. Rajanya is the older Vedic word for the warrior-ruler class, later replaced by “Kshatriya.”

Common Misconceptions About the Book

A few claims about Who Were the Shudras? show up often online, and they do not match what Ambedkar actually wrote.

Misconception: Ambedkar said Shudras were India’s original, indigenous population, later conquered and enslaved. This is close to the opposite of his argument. That “indigenous population” idea belongs to the older Western invasion theory he spends several chapters rejecting. His own claim is that Shudras were Aryans, not a conquered native people.

Misconception: Shudras are described as “descendants of Sudas.” Ambedkar never makes this claim. His argument is that the Rig Vedic king Sudas was himself a member of the Shudra group of Kshatriyas, which is a different point. He is not proposing Sudas as an ancestor of all later Shudra castes.

Misconception: the book claims today’s OBC or Shudra castes are literally descended from the ancient Kshatriya Shudras Ambedkar describes. Ambedkar is explicit that present-day Shudra castes are not the direct descendants of that original group. He describes them instead as “a collection of castes drawn from heterogeneous stocks,” explaining that the word “Shudra” later became a general label applied to many different low-ranked groups, not the name of one surviving bloodline.

Misconception: this is mainly a book about the Aryan invasion theory. The Aryan-race argument is a real part of the book, Chapters IV to VI, but it supports a larger and more specific claim: that the Shudras were originally Kshatriyas who were pushed down through the denial of Upanayana. Reducing the book to just the Aryan-invasion argument misses its central thesis.

Criticism and Scholarly Reception

Ambedkar’s book has drawn both praise and serious pushback from historians. A fair page should show both.

R.S. Sharma, a major Marxist historian, wrote the next big academic study on the subject, Shudras in Ancient India (1958). He was sharply critical of Ambedkar’s method, writing that Ambedkar worked “entirely dependent for his source material on translations” of Sanskrit texts, and that he “seems to have worked with the fixed purpose of proving a high origin for the Shudras.” Sharma also pointed out that the whole Kshatriya argument leans on a single passage from the Shanti Parva.

This criticism has real weight. Ambedkar himself admits in the preface that he does not have mastery of Sanskrit and relied on English translations for about 15 years of study, though he did have a Sanskrit scholar, Prof. Kangle, check his work. It is also worth noting that Sharma’s own book was, by his telling, the first full academic study to follow Ambedkar’s, so even a critical scholar treated Ambedkar’s 1946 book as the starting point for later research on the topic.

A.P. Karmarkar, reviewing the book in 1949, disagreed in a more measured tone. He noted the book did not discuss the Indus Valley civilisation and suggested Shudras were more likely indigenous tribes absorbed into Aryan society over time, closer to the older theory Ambedkar had rejected.

Arvind Sharma, writing in 2005, gave a more mixed and detailed assessment, but focused specifically on the Aryan-race argument rather than the Kshatriya claim. He called Ambedkar’s critique “one of the earliest coherent” challenges to the old Aryan-invasion model, and said Western scholarship had “sedulously ignored” it. He judged Ambedkar “far ahead of his times” in treating “Aryan” as a cultural label rather than a race. But he also concluded that Ambedkar’s full rejection of any Aryan migration into India “does not pass scrutiny in light of current scholarship.” His summary is useful: Ambedkar’s rejection of a “racial” Aryan invasion is now widely accepted; his rejection of any Aryan migration at all is not.

Sharad Patil, a Marxist and Ambedkarite thinker, accepted Ambedkar’s general method but reached a different conclusion, treating Dasas and Shudras as the same group and accepting an Aryan conquest model.

Outside academic circles, the book is also quoted by very different, often opposed groups. Some Hindu-nationalist writers cite Ambedkar’s rejection of the Aryan invasion theory to support their own arguments, while leaving out his harsh criticism of the Vedas themselves, including his description of the Purusha Sukta as a Brahmin “fabrication.” Scholars such as Arvind Sharma have pointed out that Ambedkar’s own motive was equality between castes, a different goal from nationalist uses of the same argument.

A fair way to read the debate: Ambedkar’s rejection of a racial “Aryan race” has aged well and is now closer to the mainstream view. His specific claim that Shudras were originally Kshatriyas rests on a single, debated textual link and has not been widely accepted by historians. Both things can be true about the same book.

Who Were the Shudras? vs Annihilation of Caste vs The Untouchables

These works form a connected set. Here is how they relate.

Work	Year	Core argument	How it connects
Annihilation of Caste	1936	Caste is not a division of labour but a “division of labourers.” Real reform is impossible as long as the Shastras, the religious law books, keep their authority, because caste is backed by religion, not just custom.	Sets up the programme that Who Were the Shudras? carries out: going through the sacred texts “chapter and verse” to strip them of their authority.
Who Were the Shudras?	1946	Shudras were originally Kshatriyas, pushed down to the fourth varna after Brahmins denied them Upanayana during a long conflict.	Puts the Annihilation of Caste programme into practice against one specific varna’s origin story.
The Untouchables: Who Were They and Why They Became Untouchables?	1948	Untouchables were originally “Broken Men,” members of defeated tribes who lived outside villages. Untouchability came from Brahmin contempt for them as Buddhists, and from their continuing to eat beef after others stopped.	Ambedkar calls this book “a sequel” to Who Were the Shudras? in its own preface. Together, the two books explain how both the fourth varna and the group below it, the Untouchables, were created.
Riddles in Hinduism	Written c. 1954-55, published 1987	Questions the origins of the Vedas, the varnas and the Hindu gods, including a section asking whether Brahmins are even sure of their own origin.	Continues the same textual criticism of the Purusha Sukta that opens Who Were the Shudras?

Why the Book Matters Today

The 2027 caste census. India’s next Census will count individual castes directly, the first count of its kind since 1931. House-listing is scheduled to run from April to September 2026, with population enumeration beginning in February 2027. The current 27% OBC reservation quota still rests on 1931 census data, extended through estimates by the Mandal Commission in 1980. Writers arguing for stronger OBC representation often quote Ambedkar’s 1946 figure that Shudras made up “75 to 80 per cent” of the Hindu population, though his estimate likely included dominant land-owning Shudra groups, such as Marathas, Jats and Patels, who are not on today’s central OBC lists.

The debate over reclaiming the “Shudra” label. Some modern Bahujan writers and scholars, such as Kancha Ilaiah Shepherd, openly use “Shudra” as a positive identity, directly building on Ambedkar’s question. Others push back, arguing that returning to the word “Shudra” pulls people back inside the same religious caste order Ambedkar wanted to dismantle. This is an active, unresolved disagreement within Bahujan politics, not a settled question.

Dalit-OBC coalition politics. The book’s dedication to Jotiba Phule as “the Greatest Shudra of Modern India,” and Ambedkar’s direct appeal to Shudra readers, “only the Shudras can destroy the Chaturvarnya,” are often cited as an early foundation for Dalit-OBC political unity, an idea that runs from Phule and Ambedkar through to Kanshi Ram’s later “Bahujan” framing.

Selective quoting by Hindu-nationalist writers. Some writers use Ambedkar’s rejection of the Aryan invasion theory to support unrelated nationalist arguments, while leaving out his equally strong rejection of the Vedas’ religious authority. Reading the whole book, rather than isolated chapters, makes this selective use easy to spot.

Kshatriya-status claims today. Many castes still classed as Shudra or OBC continue to claim Kshatriya ancestry in everyday life. Ambedkar’s own examples, different branches of the same Kayastha community ranked differently in different regions, show how unstable and locally decided these labels have always been, which is closer to his real point than any claim of “Kshatriya pride.”

Famous Quotes from Who Were the Shudras?

On the scale of the issue: “Excluding the Untouchables the Shudras form about 75 to 80 per cent of the population of Hindus.”

On who the book is written for: “The book is written for the ignorant and the uninformed Shudras, who do not know how they came to be what they are.”

On the four-varna system: “Chaturvarnya… makes the principle of graded inequality the basis for determining the terms of associated life.”

On his main method: a historian must treat all literature “to be examined and tested by accepted rules of evidence without recognizing any distinction between the sacred and the profane.”

On the Purusha Sukta: parts of the Vedas “are fabrications by Brahmins intended to serve their own purposes.”

On his key piece of evidence, the Mahabharata passage about Paijavana: “Without it, this book could not have been written.”

On the Aryan race theory: “The theory of the Aryan race set up by Western writers falls to the ground at every point.”

On persisting despite threats to his life, quoting the poet Bhavabhuti: “Time is infinite and earth is vast, some day there will be born a man who will appreciate what I have said.”

Frequently Asked Questions

Who were the Shudras, according to Ambedkar? He argued they were an Aryan people who originally ranked as Kshatriyas. After a long feud with Brahmins, they were denied Upanayana and pushed down to the fourth and lowest varna.

When was Who Were the Shudras? published, and who is it dedicated to? It was published in 1946 by Thacker & Co., Bombay. The preface is dated 10 October 1946. Ambedkar dedicated the book to Mahatma Jotiba Phule, calling him “the Greatest Shudra of Modern India.”

Were the Shudras really Kshatriyas? That is Ambedkar’s central claim, resting mainly on a Mahabharata passage describing “the Shudra Paijavana,” whom he identifies with the Rig Vedic king Sudas. Historians such as R.S. Sharma have questioned this, pointing out that it leans on a single textual reference.

What is the Brahmanic theory of Shudra origin that Ambedkar argued against? The traditional view, based mainly on the Purusha Sukta hymn and later the Manusmriti, that Shudras were created from the feet of a cosmic being and were meant, from the start, to serve the other three varnas. Ambedkar called the various versions of this story contradictory and lacking real history.

How did the Shudras become the fourth varna, in Ambedkar’s account? By losing access to Upanayana, the sacred-thread ceremony. Only Brahmins could perform it, and once they refused to perform it for the Shudra line, that group lost access to Vedic learning and the status that came with it, and fell below the Vaishyas.

Did Ambedkar accept the Aryan invasion theory? No. He argued there is no evidence in the Vedas of an “Aryan race” or of any invasion. Most scholars now agree with his rejection of a racial reading of “Aryan,” though his stronger claim, that no Aryan migration into India happened at all, is less widely accepted.

What is the sequel to Who Were the Shudras? The Untouchables: Who Were They and Why They Became Untouchables? (1948). Ambedkar calls it a direct sequel in its own preface. It argues Untouchables descended from “Broken Men,” tribal groups who became outcasts after Brahmins held them in contempt for staying Buddhist and continuing to eat beef.

Is the book free to read and share legally? Yes. It has been in the public domain in India since 1 January 2017, 60 years after Ambedkar’s death. It is reprinted in Writings and Speeches, Volume 7, and available online through ambedkar.org and archive.org.
