Ryden challenges conventional wisdom regarding the political and economic motivations behind the final decision to abolish the British slave trade in 1807. His research illustrates that a faltering sugar economy after 1799 tipped the scales in favour of the abolitionist argument and helped secure the passage of abolition.

Elizabeth Heyrick (1769-1831) and Alexander McDonnell (1794-1875) held opposing views on slavery in the British colonies at the beginning of the nineteenth century. Published in 1824 and 1827 respectively, these pamphlets remain key documents in the context of post-colonial debates.

In Slavery, Abolitionism and Empire in India, 1772–1843, Andrea Major asks why, at a time when the East India Company's expansion in India, British abolitionism, and the missionary movement were all at their height, was the existence of slavery in India so often ignored, denied, or excused? By exploring Britain's ambivalent relationship with both real and imagined slaveries in India and the official, evangelical, and popular discourses that surrounded them, she seeks to uncover the various political, economic, and ideological agendas that allowed East Indian slavery to be represented as qualitatively different from its transatlantic counterpart.

The lawyer and leading abolitionist James Stephen (1758-1832) published Volume 2 of The Slavery of the British West India Colonies Delineated in 1830. The volume is an exposure of the cruel and oppressive practice of slavery in the British West Indies. It investigates the living conditions, feeding and clothing of slave populations; the brutal practices, such as 'slave driving', involved in forcing labour; and, by comparisons of forced and free labour, argues for the complete abolition of slavery. Stephen had been the legal mastermind of the Slave Trade Act of 1807, which abolished the slave trade in the British Empire but not slavery itself. This important work was influential in directing public opinion against slavery and helped lead towards the 1833 Slavery Abolition Act. It is a key text of the nineteenth-century abolitionist movement and is vital for understanding the arguments and debates that led to abolition.
