Hinduism
The tradition the word "religion" doesn't fit
Description
Hinduism is the third-largest religion in the world by adherent count, with around 1.2 billion practitioners, almost all of them in India and the South Asian diaspora. It is also the religion that fits the Western category of religion least well. There is no founder. There is no single sacred book. There is no agreed-upon creed, no central authority, no equivalent of the pope, no equivalent of the Quran, no equivalent of the Apostles' Creed. The tradition includes monotheists and polytheists, theists who believe in many gods and atheists who do not believe in any, ascetics who renounce the world and householders who fully participate in it. Asking whether all of these people are practicing the same religion is a question the religion itself does not entirely settle.
This is partly because the term Hinduism was coined by outsiders. The word Hindu originally meant simply someone living east of the Indus River, used by Persians and later by Arabs and Europeans as a geographic and ethnic descriptor. Hinduism, as a noun naming a religion, came into use in English in the early nineteenth century and was a British colonial-administrative category an attempt to map onto India the same kind of bounded, comparable thing the colonizers had at home. The peoples thus labeled used different terms for what they were doing sanatana dharma, the eternal way, was one and would not have recognized themselves as belonging to a single religion in the European sense before they were told they did.
None of this is to say Hinduism is fictional. The traditions, texts, practices, and communities the term gathers are real, ancient, and continuous. What is contestable is whether they form a single religion or a family of related traditions the colonial administrative habit has been trying to package since the eighteenth century. The argument matters because the contemporary politics of India turn on it. Hindu nationalism, the dominant ideological force in Indian public life today, treats Hinduism as a coherent civilizational identity. Many practitioners argue the actual tradition is more plural than any nationalism can hold.
The question we're asking: what is gathered under the name Hinduism, where the name came from, and what is contested about it now.
What we'll see: the colonial origin of the category, the structure of dharma, caste and reform, and contemporary politics.

01The colonial category
The traditions that the word Hinduism now names had been developing on the Indian subcontinent for at least three thousand years before the British arrived. The Vedas, the oldest layer, were composed orally between roughly 1500 and 500 BCE, in a Sanskrit that even most Indians no longer speak. The Upanishads, philosophical reflections that developed out of the Vedic tradition, appeared around 800 to 200 BCE and contain some of the most sophisticated metaphysical thinking produced anywhere in the ancient world. The two great epics, the Mahabharata and the Ramayana, took shape over centuries between roughly 400 BCE and 400 CE, and the various puranic traditions, devotional movements, and philosophical schools developed across the next thousand years.
None of this happened under a single label. The people composing and reading these texts called themselves by their lineage, their region, their philosophical school, their devotional sect, their caste, their family deity. The category that gathered them was the loose civilizational notion of dharma a word that translates poorly because it covers law, duty, righteousness, the natural order of things, and what one is supposed to do given who one is and where one stands. The diversity within this frame was substantial. Buddhism and Jainism, which would later be classified as separate religions, originally emerged inside the same intellectual ecosystem and shared much of its vocabulary.
02The structure of dharma
What the category gathers, despite its colonial origin, has real internal structure. The Vedas remain the foundational textual layer, regarded by most traditions within Hinduism as revealed scripture, although their actual content hymns to early Indo-Aryan deities, ritual instructions, philosophical speculation is studied by relatively few practitioners. The Upanishads are the philosophical heart. Their central insight, articulated in many ways across different texts, is that the inner self, atman, is identical with the underlying ground of reality, brahman. This identity, when truly recognized, dissolves the illusion of separate selfhood and produces liberation.
Around this metaphysical core a range of paths developed. The Bhagavad Gita, composed around the second century BCE, identifies three primary yogas the path of action without attachment to results (karma yoga), the path of devotion to a personal god (bhakti yoga), and the path of knowledge (jnana yoga). Later traditions added raja yoga, the meditative path systematized by Patanjali. Hatha yoga, the postural discipline that became contemporary Western yoga, was originally a small subset of a much larger contemplative system.
03Caste and reform
Caste is the part of the Hindu inheritance that has been most controversial, both inside and outside the tradition. The classical texts that describe the four varnas, like the Manusmriti, present a hierarchical social order with brahmins at the top and the lowest castes including those once called untouchables, now Dalits outside the system entirely. How seriously these texts were taken as prescriptive law, how the system actually operated across two thousand years, and what relationship caste has to the religion's metaphysical core are all genuinely contested questions among historians and practitioners.
What is not contested is that caste discrimination was a real and often brutal feature of South Asian social life, and that reform movements have been challenging it for centuries. The bhakti devotional movements of the medieval period, from figures like Kabir, Mirabai, and the Tamil Alvars, often explicitly rejected caste hierarchy on theological grounds if every soul is one with brahman, the social ranking cannot reflect any deeper truth. The modern reform movements of the nineteenth century, like the Brahmo Samaj founded by Ram Mohan Roy in 1828, pushed against caste, sati, and other practices that the British and the reformers themselves found indefensible.
04Independence and Hindutva
Indian independence in 1947 was framed as a secular project. Nehru, the first prime minister, was committed to a state that did not privilege any religion, and the constitution drafted under Ambedkar enshrined that principle. The country was partitioned along religious lines into India and Pakistan, with massive violence and population displacement, but the surviving Indian state was explicitly multi-religious, with substantial Muslim, Christian, Sikh, Buddhist, Jain, and Parsi minorities alongside the Hindu majority.
Running alongside the Nehruvian secular project was a different vision, articulated since the 1920s by figures like V.D. Savarkar and the Rashtriya Swayamsevak Sangh, which held that India was essentially a Hindu civilization and that its political identity should reflect that. Hindutva, the term Savarkar coined in 1923, has been the long-developing alternative to the secular vision. For most of the twentieth century it was a minority position. Since the 1980s it has become increasingly central, and since the Bharatiya Janata Party came to dominant national power in 2014, it has become the governing ideology of the world's largest democracy.
05Conclusion
Hinduism, taken seriously, is a category that strains its own boundaries. The traditions it gathers are old, internally diverse, philosophically rich, and resistant to the kind of single-religion framing the European category implies. The colonial administrative habit produced a unified label, and the label has had real effects, both in shaping how the tradition presents itself and in producing the political movement that now claims to speak for it. None of this means the practices and texts the label gathers are anything other than real, lived, and consequential.
