Abstract

Between the mid-seventeenth and the late-eighteenth centuries thousands of enslaved people were brought to the British Isles. Many were enslaved, and they were publicly bought and sold, marked by brands, collars and manacles, and some were sent from Britain into plantation slavery. Slavery did not, hoverer, flourish in Britain. By the time of Somerset v Stewart (1772) and Knight v Wedderburn (1778) the large majority of people of color in Britain were free, many of them self-liberated. Despite the best efforts of enslavers to maintain their property rights in people, the enslaved regularly escaped. Newspaper “runaway advertisements” were invented in London during the second half of the seventeenth century, and between the 1650s and 1770s they reveal the development of the freedom seeker in the public sphere. The Somerset and Knight decisions did little to change slavery in the British Isles but rather confirmed a change that was all but complete. The most significant impact of the decisions was in the colonies, where planters interpreted the courts’ actions as evidence of a growing imperial threat to the institution of slavery
