When slavery ended in the British Empire in 1833,
plantation owners turned to indentured servitude for
inexpensive labor. These servants arrived from across the
globe; the majority came from India where many indentured
laborers came from to work in colonies requiring manual
labor. As a result, today Indo-Caribbeans form a majority
in Guyana, a plurality in Trinidad and Tobago and
Suriname, and a substantial minority in Jamaica, Grenada,
Barbados, St Lucia and other Caribbean islands.[11][84]
The British government finally ended indentures in the
Caribbean in 1917 by prohibiting the further
transportation of persons from India for purposes of
servitude for debt.[12]
