On this day, 19 June 1937, after employers failed to agree to oil workers’ pay demands, workers at one of Trinidad’s oilfields went on strike. British colonial authorities attempted to arrest Uriah Butler, a former oil worker-turned preacher, who was helping to lead the dispute. But he was defended by a crowd of workers, who killed two policemen – soaking one of them with paraffin and burning them. Butler (pictured) then went into hiding. The strike quickly spread across all oilfields, then to the rest of the economy. A state of emergency was declared and two British warships rushed to the island, arriving on 22 and 23 June, bringing marines and additional police from England and Ireland. Two local military units were also mobilised against the workers, and after numerous arrests and imprisonments the rebellion was quashed. Butler was captured in September and jailed for 2 years for sedition.
