James was born in Liverpool, to a family enriched by his grandfather
William James (1735–1798), a slave trader, plantation owner and slave owner. He was baptised at a
Paradise Street Unitarian Chapel in Liverpool, but later practised as an
Anglican. He was educated at
Eton and
Jesus College, Cambridge, then
Trinity College, Cambridge. When his grandfather died in 1798, the Clifton Hill Plantation at
Saint Thomas-in-the-East, Jamaica was placed in a trust which passed to young William in 1817. The
Slavery Abolition Act 1833 abolished slavery throughout the
British Empire, but paid compensation to slave-owners for the loss of their property. The £20 million total cost amounted to 40% of the United Kingdom's annual budget. James was awarded £4,713 14 shillings and 9 pennies (equivalent to £ in ). == Career ==
