"The West India Committee was formed in the 18th century by a permanent association of London merchants engaged in the West Indian trade, and absentee owners of West Indian estates who lived in London and its environs. ...The Committee acted as a pressure group for West Indian interests, principally in the support of the sugar and rum trades and, in the first decades of its existence, in opposition to the abolition of the slave trade and then slavery. Although the campaign against slavery eventually won the day, the West India Committee did manage to secure improved compensation terms for the planters and merchants it represented. Following the abolition of slavery in 1834, and a short period of virtual inactivity, the Committee shifted its work firstly towards the encouragement of immigrant labour from India, China and Africa (to replace the emancipated slave labour), and then to opposing the removal of preferential sugar duties for West Indian sugar."
