Colonial laws maintained the social and physical security of English settlements in the New World. This essay compares those laws that attempted to define and regulate servants and labour in seventeenth-century Virginia and Jamaica.

Earlier laws reflect a greater concern with the economic value of labour. In the last two decades, however, the laws defined new social constructs that would dominate slave laws in the next century.
