# American & French Revolutions

The American and French Revolutions in UPSC GS-1 framing: causes, ideological roots, key documents, phases, and their global legacy.

## The American Revolution (1765–1783)

The American Revolution transformed thirteen British colonies into a sovereign republic and supplied the first working model of a written constitution founded on popular sovereignty. UPSC treats it as the political application of Enlightenment thought—John Locke's *Two Treatises of Government* (1689), with its doctrine of natural rights (life, liberty, property) and government by consent.

### Causes

The immediate trigger was Britain's post-1763 fiscal policy after the Seven Years' War. Parliament imposed the Sugar Act (1764), the Stamp Act (1765) and the Townshend Acts (1767) to tax the colonies, provoking the rallying cry "No taxation without representation." The Boston Massacre (March 1770) and the Boston Tea Party (16 December 1773) escalated the conflict; Britain retaliated with the Coercive ('Intolerable') Acts of 1774. The First Continental Congress convened that year.

### Course and documents

Armed conflict began at Lexington and Concord (April 1775). The Second Continental Congress adopted the **Declaration of Independence on 4 July 1776**, drafted principally by Thomas Jefferson, asserting that "all men are created equal" and endowed with "unalienable Rights." Thomas Paine's pamphlet *Common Sense* (January 1776) had earlier galvanised public opinion for separation. The decisive military turn came at Saratoga (1777), which brought France into the war as an ally (Treaty of Alliance, 1778). The British surrender at Yorktown (1781) ended the fighting; the **Treaty of Paris (1783)** recognised American independence.

### Constitutional legacy

The weak Articles of Confederation (ratified 1781) gave way to the **United States Constitution (1787)**, which institutionalised federalism, separation of powers and checks and balances—ideas drawn from Montesquieu's *The Spirit of the Laws* (1748). The **Bill of Rights (1791)**, the first ten amendments, entrenched individual liberties. The revolution exported republicanism and inspired the French revolutionaries, Latin American liberators such as Simón Bolívar, and later anti-colonial movements. For UPSC, note the contradiction the exam frequently probes: a republic proclaiming equality while preserving slavery (abolished only by the Thirteenth Amendment, 1865) and excluding women and indigenous peoples from citizenship. The revolution's significance lies less in social upheaval than in constitutional innovation—it was a political revolution that left the social order largely intact, a contrast UPSC routinely sets against the French experience.
