British rule led to an influx of settlers from the United Kingdom and the British colonies of the Eastern Caribbean. English, Scots, Irish, German and Italian families arrived, as well as some free blacks known as "Merikins" who had fought for Britain in the War of 1812 and were granted land in southern Trinidad. Under British rule, new states were created and the importation of slaves increased, however by this time support for abolitionism had vastly increased and in England the slave trade was under attack. Slavery was abolished in 1833, after which former slaves served an "apprenticeship" period.  In 1837 Daaga, a West African slave trader who had been captured by Portuguese slavers and later rescued by the British navy, was conscripted into the local regiment. Daaga and a group of his compatriots mutinied at the barracks in St Joseph and set out eastward in an attempt to return to their homeland. The mutineers were ambushed by a militia unit just outside the town of Arima. The revolt was crushed at the cost of some 40 dead, and Daaga and his party were later executed at St Joseph. The apprenticeship system ended on 1 August 1838 with full emancipation. An overview of the populations statistics in 1838, however, clearly reveals the contrast between Trinidad and its neighbouring islands: upon emancipation of the slaves in 1838, Trinidad had only 17,439 slaves, with 80% of slave owners having enslaved fewer than 10 people each. In contrast, at twice the size of Trinidad, Jamaica had roughly 360,000 slaves.
