How many times was Arthur Wellesley, 1st Duke of Wellington, British prime minister?

Field Marshal Arthur Wellesley, 1st Duke of Wellington, KG, GCB, GCH, PC, FRS (1 May 1769 – 14 September 1852) was an Anglo-Irish soldier and statesman, and one of the leading military and political figures of 19th-century Britain. His defeat of Napoleon at the Battle of Waterloo in 1815 put him in the top rank of Britain's military heroes. In 2002, he was number 14 in the BBC's poll of the 100 Greatest Britons.

After ending his active military career, Wellesley returned to politics. He was twice British prime minister as part of the Tory party: from 1828 to 1830, and for a little less than a month in 1834. He oversaw the passage of the Catholic Relief Act 1829, but opposed the Reform Act 1832. He continued as one of the leading figures in the House of Lords until his retirement and remained Commander-in-Chief of the British Army until his death.
