Personal narrative of James Williams, an apprenticed labourer in Jamaica, written when he was about eighteen years old. The Slave Trade Act was passed by the British Parliament on 25 March 1807, making the slave trade illegal throughout the British Empire. Slaves were still held, though not sold, within the British Empire. In the 1820s, the abolitionist movement again became active, this time campaigning against the institution of slavery itself. In 1823 the first Anti-Slavery Society was founded in Britain. Many of the campaigners were those who had previously campaigned against the slave trade. On 28 August 1833, the Slavery Abolition Act was given Royal Assent, which paved the way for the abolition of slavery within the British Empire and its colonies. On 1 August 1834, all slaves in the British Empire were emancipated, but they were indentured to their former owners in an apprenticeship system which was abolished in two stages; the first set of apprenticeships came to an end on 1 August 1838, while the final apprenticeships ended two years later on 1 August 1840.
