In the United Kingdom, the interwar period (1918–1939) was a period of relative stability after the division of Ireland, though of economic stagnation. In politics, the Liberal Party collapsed and the Labour Party became the main challenger to the dominant Conservative Party throughout the period. The Great Depression affected Britain less severely economically and politically than other major nations, although some areas still suffered from severe long-term unemployment and hardship, especially mining districts and in Scotland and North West England.
