The rise of Irish nationalism, and disputes within Ireland over the terms of Irish Home Rule, led eventually to the partition of the island in 1921. The Irish Free State became independent, initially with Dominion status in 1922, and unambiguously independent in 1931. Northern Ireland remained part of the United Kingdom. The 1928 Act widened suffrage by giving women electoral equality with men. A wave of strikes in the mid-1920s culminated in the General Strike of 1926. Britain had still not recovered from the effects of the war when the Great Depression (1929–1932) occurred. This led to considerable unemployment and hardship in the old industrial areas, as well as political and social unrest in the 1930s, with rising membership in communist and socialist parties. A coalition government was formed in 1931.
