What happened
In late 1929, women across the Owerri and Calabar provinces of southeastern Nigeria launched a mass protest against the British-appointed warrant chiefs and against the fear that colonial authorities were about to extend taxation to women. The spark came on the morning of November 18, when a woman named Nwanyeruwa clashed with a census taker counting her household, which she understood as preparation for taxing her. Word spread through women's networks and a protest of ten thousand women grew into an uprising of tens of thousands across a region of thousands of square miles, using the traditional practice of sitting on a man to shame and pressure the warrant chiefs. Over a two-month period colonial forces killed at least fifty women. The uprising, known in Igbo as Ogu Umunwanyi, forced Britain to drop the plan to tax women and to curb, and eventually dismantle, the warrant-chief system.
Why it matters
The Women's War is remembered as the first major organized challenge to British colonial rule in Nigeria and one of the most significant anti-colonial protests in the history of the British Empire, led entirely by rural women. It exposed how indirect rule through appointed warrant chiefs had broken existing structures in which Igbo women held real authority, and it won concrete reversals of colonial policy that few later protests matched.
How we know
The events, casualties, and outcomes are documented in British colonial commission-of-inquiry records from 1929 to 1930 and synthesized in university-hosted scholarship at Swarthmore College and the Open University.
