Arthur Wellesley, 1st Duke of Wellington,  (1 May 1769 - 14 September 1852), was an Anglo-Irish soldier and statesman who was one of the leading military and political figures of 19th-century Britain, serving twice as Prime Minister. His defeat of Napoleon at the Battle of Waterloo in 1815 puts him in the first rank of Britain's military heroes. Wellesley was born in Dublin, into the Protestant Ascendancy in Ireland. He was commissioned as an ensign in the British Army in 1787, serving in Ireland as aide-de-camp to two successive Lords Lieutenant of Ireland.

Despite his new promise, he had yet to find a job and his family was still short of money, so upon the advice of his mother, his brother Richard asked his friend the Duke of Rutland (then Lord Lieutenant of Ireland) to consider Arthur for a commission in the Army. Soon afterward, on 7 March 1787, he was gazetted ensign in the 73rd Regiment of Foot. In October, with the assistance of his brother, he was assigned as aide-de-camp, on ten shillings a day (twice his pay as an ensign), to the new Lord Lieutenant of Ireland, Lord Buckingham. He was also transferred to the new 76th Regiment forming in Ireland and on Christmas Day, 1787, was promoted to lieutenant. During his time in Dublin his duties were mainly social; attending balls, entertaining guests and providing advice to Buckingham. While in Ireland, he overextended himself in borrowing due to his occasional gambling, but in his defence stated that "I have often known what it was to be in want of money, but I have never got helplessly into debt".  On 23 January 1788, he transferred into the 41st Regiment of Foot, then again on 25 June 1789, still a lieutenant, he transferred to the 12th (Prince of Wales's) Regiment of (Light) Dragoons and, according to military historian Richard Holmes, he also dipped a reluctant toe into politics. Shortly before the general election of 1789, he went to the rotten borough of Trim to speak against the granting of the title "Freeman" of Dublin to the parliamentary leader of the Irish Patriot Party, Henry Grattan. Succeeding, he was later nominated and duly elected as a Member of Parliament (MP) for Trim in the Irish House of Commons. Because of the limited suffrage at the time, he sat in a parliament where at least two-thirds of the members owed their election to the landowners of fewer than a hundred boroughs. Wellesley continued to serve at Dublin Castle, voting with the government in the Irish parliament over the next two years. He became a captain on 30 January 1791, and was transferred to the 58th Regiment of Foot.  On 31 October, he transferred to the 18th Light Dragoons and it was during this period that he grew increasingly attracted to Kitty Pakenham, the daughter of Edward Pakenham, 2nd Baron Longford. She was described as being full of 'gaiety and charm'. In 1793, he sought her hand, but was turned down by her brother Thomas, Earl of Longford, who considered Wellesley to be a young man, in debt, with very poor prospects. An aspiring amateur musician, Wellesley, devastated by the rejection, burnt his violins in anger, and resolved to pursue a military career in earnest. He became a major by purchase in the 33rd Regiment in 1793. A few months later, in September, his brother lent him more money and with it he purchased a lieutenant-colonelcy in the 33rd.
