Enlightenment

Story hook

In 1685, a 53-year-old English physician was living in exile in the Dutch Republic, having fled England under suspicion of plotting against King Charles II. His name was John Locke. In Holland — Europe's one island of relative free press — he finished a short book arguing something close to treason: that government is not a gift from God to kings, but a trust granted by free men, which they may revoke if the ruler breaks faith. When the Glorious Revolution of 1688 chased the Catholic James II off the throne, Locke sailed home and published his Two Treatises of Government (1689) — almost a manifesto for the bloodless coup that had just happened.

Thirty-eight years earlier and on the other side of the English Civil War, a frightened mathematician named Thomas Hobbes had reached the opposite conclusion. Watching England tear itself apart, Hobbes wrote Leviathan (1651) to argue that the only escape from a "war of all against all" was to surrender every freedom to one all-powerful sovereign. Two Englishmen, one generation apart, looking at the same chaos — and one prescribed absolute power while the other prescribed limited, accountable government.

The argument they began was not academic. A century later a 26-year-old named Thomas Jefferson sat in a Philadelphia boarding house and wrote that all men are "endowed by their Creator with certain unalienable Rights" — lifting Locke almost verbatim. In a Paris hall in 1789, French deputies passed the Declaration of the Rights of Man and of the Citizen, echoing Montesquieu on the separation of powers. The Enlightenment was the laboratory in which Europe rebuilt the idea of legitimate authority from scratch — and the blueprint it drew up still governs you today.

Why this matters for UPSC

The Enlightenment sits in GS-I "World History" as the intellectual engine of every revolution that follows it — American (1776), French (1789), and the wider rise of liberalism. Prelims has asked which thinker influenced the US Constitution (Montesquieu, Locke), who wrote Leviathan, and matching-pairs of thinker-to-text. Mains and the Essay paper lean on it heavily: any question on liberalism, liberal democracy, natural rights, secularism, or the social contract needs Enlightenment scaffolding.
