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.

Wellesley was born into an aristocratic Anglo-Irish family in Ireland as The Hon. Arthur Wesley, the third of five surviving sons (fourth otherwise) to Anne and Garret Wesley, 1st Earl of Mornington. His mother was the eldest daughter of The 1st Viscount Dungannon. As such, he belonged to the Protestant Ascendancy. His biographers mostly follow the same contemporary newspaper evidence in saying that he was born on 1 May 1769, the day before he was baptised. His birthplace is uncertain. He was most likely born at his parents' townhouse, 24 Upper Merrion Street, Dublin, now the Merrion Hotel. But his mother Anne, Countess of Mornington, recalled in 1815 that he had been born at 6 Merrion Street, Dublin. Other places have been put forward as the location of his birth, including Mornington House (the house next door on Upper Merrion), as his father had asserted; the Dublin packet boat; and the mansion in the family estate of Athy (consumed in the fires of 1916), as the Duke apparently put on his 1851 census return.  He spent most of his childhood at his family's two homes, the first a large house in Dublin and the second Dangan Castle, 3 miles (5 km) north of Summerhill on the Trim Road (now the R158) in County Meath. In 1781, Arthur's father died and his eldest brother Richard inherited his father's earldom.  He went to the diocesan school in Trim when at Dangan, Mr Whyte's Academy when in Dublin, and Brown's School in Chelsea when in London. He then enrolled at Eton College, where he studied from 1781 to 1784. His loneliness there caused him to hate it, and makes it highly unlikely that he actually said "The Battle of Waterloo was won on the playing fields of Eton", a quotation which is often attributed to him. Moreover, Eton had no playing fields at the time. In 1785, a lack of success at Eton, combined with a shortage of family funds due to his father's death, forced the young Wellesley and his mother to move to Brussels. Until his early twenties, Arthur showed little sign of distinction and his mother grew increasingly concerned at his idleness, stating, "I don't know what I shall do with my awkward son Arthur."  A year later, Arthur enrolled in the French Royal Academy of Equitation in Angers, where he progressed significantly, becoming a good horseman and learning French, which later proved very useful. Upon returning to England in late 1786, he astonished his mother with his improvement.
