Inter-war period

Story hook

Thursday, 24 October 1929. New York Stock Exchange, 11 Wall Street. At 11 a.m. trading opened in chaos. By noon, US Steel had dropped from 205 to 193, General Motors from 73 to 65, Radio Corporation of America from 68 ½ to 44 ½. Bankers gathered at J.P. Morgan & Co. to stage a confidence-restoring buy-in. Friday brought a brief recovery. Then came Black Monday 28 October (Dow down 12.8 %) and Black Tuesday 29 October (Dow down 11.7 % on a record 16.4 million shares traded — a volume that wasn't surpassed until 1968). In seven trading sessions, $30 billion in market value had vanished — roughly the same dollar amount the US had spent on the entire First World War. Within three years, the Dow Jones Industrial Average would fall from a peak of 381 (3 September 1929) to a trough of 41 (8 July 1932) — an 89 % collapse.

By 1932 there were 13 million Americans unemployed (25 % of the workforce), one-third of US banks had failed, and global trade had shrunk by two-thirds. In Germany, 6 million were unemployed, and a 43-year-old Austrian failed-painter named Adolf Hitler — whose Nazi Party had won 2.6 % of the vote in 1928 — was about to win 37.3 % in July 1932 to become the largest party in the Reichstag. In Italy, Benito Mussolini had been Prime Minister since 1922 and dictator since 1925. In Tokyo, junior army officers were murdering moderate politicians in coup attempts. In just twelve years — between the Treaty of Versailles signed in 1919 and the Japanese invasion of Manchuria in 1931 — the post-war order was breaking down. By 1939, the world would be back at war.

Why this matters for UPSC

UPSC's GS-I "Significant events" syllabus treats the inter-war period as the bridge between the two World Wars — and as a laboratory for understanding how democracies fail under economic and ideological stress. Prelims has asked about the Great Depression, New Deal, Beer Hall Putsch, March on Rome, Munich Agreement (1938). Mains framings ask about Versailles → Nazism, the failure of collective security, and fascism vs democracy. Weight: medium for Prelims, high for Mains.
