Fundamentalism is the assertion that a religious tradition rests on an inerrant foundation — a scripture, a law, a body of doctrine held to be without error and beyond negotiation — coupled with the demand that personal conduct and public institutions be brought into conformity with it. Two elements must be present together. The first is epistemic: the foundational text is treated as self-sufficient, its meaning plain, its authority immune to historical criticism. The second is political: the fundamentalist is not content with private devotion but seeks to reshape law, education, family and the state.
The crucial sociological claim is that fundamentalism is modern, not archaic. It is not a leftover from a pre-scientific age but a reaction against secular modernity that uses modernity's own instruments. Ancient believers did not need to insist on the inerrancy of scripture because no one had subjected it to textual criticism, Darwinism or comparative religion. Fundamentalism is the answer to those challenges — which is why Martin Riesebrodt could treat American Protestant militancy and Iranian clerical mobilisation as variants of a single modern form.
Origins of the term
The word derives from The Fundamentals, a series of pamphlets published in the United States between 1910 and 1915 defending doctrines held to be non-negotiable: the inerrancy of the Bible, the virgin birth, substitutionary atonement, bodily resurrection and the authenticity of miracles. The label fundamentalist was coined in 1920 for Protestants willing to do battle for these points, and the Scopes trial of 1925 fixed the image of a religion at war with science.
Its extension beyond Protestantism was the work of the Fundamentalism Project directed by Martin Marty and R. Scott Appleby, whose comparative volumes traced analogous movements in Judaism, Islam, Hinduism, Sikhism and Buddhism. The extension is contested. Critics object that a term rooted in Protestant bibliolatry travels badly to traditions where scripture is recited rather than interpreted, where authority is diffused among schools of law, or where — as in Hinduism — there is no single canonical text to be read literally.
Distinguishing the neighbours
Precision here separates a good answer from a vague one. Orthodoxy is the settled maintenance of received doctrine and practice; it may be conservative but it is untroubled, and it does not need to mobilise. Fundamentalism is orthodoxy made militant by the perception of threat. Revivalism is the renewal of fervour and observance within a tradition — it may be emotional, devotional and politically quiet. Communalism organises a religious population as a political interest group against another; its content is antagonism between communities, not doctrinal purity, and it can be led by people of little personal piety. Terrorism is a tactic, available to secular nationalists and left revolutionaries alike; some fundamentalists adopt it, most do not, and to equate the two is analytically useless.
Features
Five recurring features are worth naming. Literalism or scriptural inerrancy — although in practice selective, since every movement reads some passages as binding and others as figurative. Boundary-setting: sharp distinctions between the faithful and the world, expressed in dress, diet, schooling and marriage, so that the group maintains what Steve Bruce calls a plausibility structure of its own. Moral absolutism and a dualistic reading of history as a struggle between truth and error. A charismatic and usually male leadership, often outside the established clerical hierarchy. And, paradoxically, the selective embrace of modern technique — cassette sermons, satellite television, digital platforms, modern accounting, professional cadres and schools — while modern values of pluralism and doubt are rejected. Almond, Appleby and Sivan add the characteristic reactivity: the movement is defined by what it opposes.
The Indian debate
India offers material across communities, and also the strongest case for handling the term carefully. Assertive movements have appeared among Hindus seeking a unified religious nation, among Muslims defending personal law and seminary orthodoxy, among Sikhs demanding a purified panth in the Punjab of the 1980s, and among Christian groups insisting on biblical inerrancy. Yet the fit is uneven. Hindu mobilisation has been political and symbolic rather than scripturalist — it is more accurately read as communalism or religious nationalism than as literalism about a text. Movements to purify practice by removing accretions, or to codify what was diffuse, look more like the pursuit of a bounded, textual religion of the modern kind than a return to any past.
T. N. Madan argued in Modern Myths, Locked Minds that Indian secularism, by declaring religion a private matter for people whose lives are lived religiously, left the field of public religious meaning open to the least generous voices. On this reading, fundamentalism in India is not the failure of modernity to arrive but a product of the way it arrived — through a state that managed religion without understanding it.
For the UPSC answer
Lead with the definition — inerrant foundation plus the demand that public life conform — and immediately state the sociological point that fundamentalism is a modern reaction to secular modernity, not a survival from the past. Spend a paragraph separating it from orthodoxy, revivalism, communalism and terrorism, because most weak answers collapse all four. Give the Protestant American origin of the term and the Fundamentalism Project's extension, then note the South Asian difficulty: without a single canonical text, Hindu mobilisation is better analysed as communalism or religious nationalism. Close with Madan's argument that the Indian variety grew from the way secularism was institutionalised.
