When did William Wilberforce and the abolitionists began their fight against the slave trade in Britain how much of Britain and economy was dependent upon the slave trade?

William Wilberforce and the abolitionists began their campaign against the slave trade in Britain in the late 18th century, gaining significant momentum in the 1780s. By the early 19th century, it is estimated that around 15% of Britain's economy was directly or indirectly dependent on the slave trade and the profits generated from slave-produced goods, particularly sugar and tobacco. This economic reliance made the abolitionist movement a complex and challenging struggle against entrenched interests. Wilberforce's tireless efforts culminated in the passing of the Abolition of the Slave Trade Act in 1807.
