The parish has a population of 94,410. During the nineteenth century, the parish was an area of sugar cane plantations, with a majority of black enslave descendant after the abolition of slavery. The Morant Bay Rebellion started on October 11, 1865, with a march by hundreds of people from the parish to the court house to protest poor conditions in the parish. After seven men were shot and killed by volunteer militia, the people burned the court house and other nearby buildings; a total of 25 people died on both sides in this confrontation.
