Between 1812 and 1821 Goulburn worked in the War and Colonial Office, where he effectively administered Britain's far-flung possessions. Appointed chief secretary for Ireland in 1821 -- a Protestant to offset a "Catholic" viceroy -- Goulburn was at the heart of the final rearguard action by the opponents of Catholic emancipation. As chancellor of the exchequer for the Duke of Wellington (1828-30) and Sir Robert Peel (1841-46) he participated in such momentous decisions as Catholic emancipation and the repeal of the Corn Laws. An opponent of parliamentary reform, he worked closely with Peel, his lifelong friend, to build the Conservative Party and served as a parliamentary champion of the Established Church. Jenkins examines the conservative values Goulburn held, and the moral dilemma of an essentially good man who depended on the institution of slavery for his private income.
