After an admirable speech, Wilberforce laid on the table twelve resolutions which were intended as the basis of a future motion for the abolition of the trade.
On the 2nd of April 1792 Wilberforce again moved that the trade ought to be abolished; an amendment in favour of gradual abolition was carried, and it was finally resolved that the trade should cease on the 1st of January 1796.
An appeal was made by Wilberforce in 1821 to Thomas Fowell Buxton to undertake the conduct of this new question in parliament.
An anti-slavery society was established in 1823, the principal members of which, besides Wilberforce and Buxton, were Zachary Macaulay, Dr Lushington and Lord Suffield.
He preached his last sermon in Mr Belson's house at Leatherhead on Wednesday, the 23rd of February 1791; wrote next day his last letter to Wilberforce, urging him to carry on his crusade against the slave trade; and died in his house at City Road on the 2nd of March 1791, in his eighty-eighth year.
