Example Input: Question: Who preceded Henry Goulburn as Chief Secretary for Ireland? Passage:In 1808, Goulburn became Member of Parliament for Horsham. In 1810, he was appointed Under-Secretary of State for Home Affairs, and two and a half years later, he was made Under-Secretary of State for War and the Colonies. It was in this capacity that James Meehan named Goulburn, New South Wales after him, a naming that was ratified by Governor Lachlan Macquarie. Still retaining office in the Tory government, he became a Privy Counsellor in 1821, and shortly afterwards was appointed Chief Secretary for Ireland, a position which he held until April 1827. Here, although he was frequently denounced as he was considered an Orangeman, he had a successful period of office on the whole, and in 1823 he managed to pass the Composition for Tithes (Ireland) Act 1823. In January 1828, he was made Chancellor of the Exchequer under the Duke of Wellington; like his leader, he disliked Roman Catholic emancipation, which he voted against in 1828.
