The 1926 general strike in the United Kingdom was a general strike that lasted nine days, from 4 to 12 May 1926. It was called by the General Council of the Trades Union Congress (TUC) in an unsuccessful attempt to force the British government to act to prevent wage reductions and worsening conditions for 1.2 million locked-out coal miners. Some 1.7 million workers went out, especially in transport and heavy industry.
It was a sympathy strike, with many of those who were not miners and not directly affected striking to support the locked-out miners. The government was well prepared, and enlisted middle class volunteers to maintain essential services. There was little violence and the TUC gave up in defeat.
From 1914 to 1918, the United Kingdom participated in World War I. Heavy domestic use of coal during the war depleted once-rich seams. Britain exported less coal during the war than it would have in peacetime, allowing other countries to fill the gap. This particularly benefited the strong coal industries of the United States, Poland, and Germany. In the early 1880s, coal production was at a peak of 310 tons per man annually, but in the four years preceding the war, this amount had fallen to 247 tons. By the 1920–1924 period, this had fallen further to just 199 tons. Total coal output had been in decline since 1914 as well.
In 1924, the Dawes Plan was implemented. It allowed Germany to re-enter the international coal market by exporting "free coal" to France and Italy, as part of their reparations for the war. This extra supply reduced coal prices. In 1925, Winston Churchill, the chancellor of the Exchequer, reintroduced the gold standard. This made the British pound too strong for effective exporting to take place from Britain. Furthermore, because of the economic processes involved in maintaining a strong currency, interest rates were raised, which hurt some businesses.
Mine owners wanted to maintain profits even during times of economic instability, which often took the form of wage reductions for miners in their employment.
