Working indefatigably, he researched and found the murky truths about the trade in human beings that brought so much wealth to so many and so much suffering to many more. He raised awareness up and down the country, covering some thirty five thousand miles on horseback in seven years from 1787 when the Committee for the Abolition of the Slave Trade was formed. He worked in effective partnership with William Wilberforce, who became the voice of the Abolitionists in parliament.
They were the little and large of the campaign. While Wilberforce barely scraped the five foot bar, Clarkson was over six foot tall with flaming red hair, which made him an obvious target for some who were pro-slavery. He was an eloquent man, highly intelligent, educated.
Which makes it quite odd that in the film, Amazing Grace, Clarkson was prtrayed by Rufus Sewell as a mumbling yokel in a bad wig.
On Saturday morning, I shall be leading a guided walk around the City of London about the campaign for the abolition of slavery, and taking about some of the key figures, ncluding Clarkson and Wilberforce.
Join me outside the Monument tube at 10.45 for a walk that lasts about two hours.
