Besides travelling through many states of the United States to deliver anti-slavery lectures, Lundy visited Haiti twice - in 1825 and 1829, the Wilberforce colony of freedmen and refugee slaves in Canada in 1830-1831, and in 1832 and again in 1833 Texas, all these visits being made, in part, to find a suitable place outside the United States to which emancipated slaves might be sent.
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.
