As crown colonies, St. Lucia and Trinidad were denied legislative assemblies and were instead ruled by metropolitan Orders in Council. In the eyes of British colonial officials, such colonies were therefore ideal sites for reform and experimentation. Despite concerted resistance from resident planters, it was here that policies later extended throughout the empire, such as the compulsory registration of all enslaved people, were first enacted. This paper focuses on how enslaved people in these little-studied colonies experienced and responded to these imperial projects. As abolitionists and members of the planter lobby in London debated the future of slavery, tens of thousands of men and women in the southern Caribbean were subjected to changes in the nature and intensity of labor they performed, where and with whom they resided, and the regime under which they lived. By highlighting the changing realities of slavery during an era usually associated with abolition, this paper calls attention to how enslaved people navigated broader imperial changes.
