The records of the slave registries are among the most important and comprehensive for slave research in the British West Indies for the period 1812 to 1834. The slave registers provide a census of all slaves and slave holders until the abolition of slavery on 1 August 1834.
Between 1812 and 1834 the British government and Anglo-Caribbean colonial governments registered the enslaved population to help manage the illegal movement of slaves following the abolition of the slave trade. See my article on slave registers for more information.
Original returns may survive in the local Caribbean archive, though none have been found for Barbados. From 1819 copies (including the Barbados returns) were sent to the London Registry and these are held by The National Archives under the reference T 71
The registers were later used as evidence of slave ownership for the compensation awards following the abolition of slavery in 1834. A brief description of the awards and a database of the Barbados awards is on the Caribbean Family History website. A more extensive database for the all countries with biographical and other information on slave holders is at Legacies of British Slave-ownership.
