Member of Parliament, 1804–1812 Robinson entered politics through a family connection. His mother's cousin, the
third Earl of Hardwicke,
Lord Lieutenant of Ireland, appointed him as his private secretary in 1804. Two years later Hardwicke secured for him the parliamentary seat of
Carlow, a
pocket borough near Dublin. In 1807 Robinson gave up the seat and was elected as MP for
Ripon, close to his family home in Yorkshire.
First political appointments: 1807–1812 In his first years in Parliament Robinson declined offers of junior ministerial posts, out of deference to his patron Hardwicke, who was an opponent of the Prime Minister, the
Duke of Portland. The mission was unsuccessful, but Robinson's reputation was not damaged, and, as his biographer E Royston Pike puts it, "as a good Tory [he was] given several small appointments in successive ministries." His political thinking was greatly influenced by Canning, but he became the protégé of Canning's rival
Lord Castlereagh, who appointed him his under-secretary at the
War Office in May 1809. When Castlereagh resigned from the government in October, unwilling to serve under the new Prime Minister,
Spencer Perceval, Robinson resigned with him.
Marriage In 1814 Robinson married
Lady Sarah Hobart (1793–1867), daughter of the
4th Earl of Buckinghamshire, and first cousin to
Castlereagh's wife. There were three children of the marriage, only one of whom survived to adulthood: • Eleanor Henrietta Robinson (22 May 1815 – 31 October 1826) • Hobart Frederick Robinson (baptised 8 September 1816 – 14 September 1816) •
George Frederick Samuel Robinson, 1st Marquess of Ripon (24 October 1827 – 9 July 1909) == Senior Minister: 1812–1822==
