Wilberforce, born to a prosperous family, chose a life of public service and adherence to Evangelical values over the comfortable merchant existence that was laid out for him. Of a conservative bent, Wilberforce was actively hostile to radicals and revolutionaries, but championed one of the great liberal causes of all time--the abolition of slavery--and was an invaluable contributor to its ultimate success. When Parliament finally outlawed the slave trade in 1807, Wilberforce did not rest on his laurels but took part in the campaign for the abolition of slavery itself. He never held or desired a cabinet post, but became an expert in any subject he addressed as a member of Parliament. And although his convictions were informed by deep religious fervor, he never hesitated to change his mind upon reflection. Hague captures all of these nuances and complexities in this clear-eyed, humane, and moving biography.
