Afro-Caribbeans are Caribbean people who trace their heritage to Sub-Saharan Africa in the period since Christopher Columbus's arrival in the region in 1492. Other names for the group include African-Caribbean (especially in the UK branch of the diaspora), Afro-Antillean or Afro-West Indian. Between the 16th and 19th centuries, European-led triangular trade brought African people to work as slaves in the Caribbean on various plantations. Many Afro-Caribbeans also have non-African ancestry, such as European, South Asian, East Asian, Middle Eastern and Native American, as there has been intermarriage over the centuries.
