Baron Rankeillour, of Buxted in the County of Sussex, is a title in the Peerage of the United Kingdom.^[1] It was created in 1932 for the Conservative politician James Fitzalan Hope. He was the grandson of General Sir Alexander Hope, fourth son of John Hope, 2nd Earl of Hopetoun (from whom the Marquesses of Linlithgow descend; see this title for earlier history of the family). His eldest son, Arthur Hope (from 1949, the second Baron), was also a Conservative politician and held junior ministerial office. From 1940 to 1946 he served as Governor of Madras. He was succeeded by his younger brother, the third Baron, Henry John Hope. After the death of Henry John Hope's only son, Peter St Thomas More Hope in 2005, (the fourth Baron), who was unmarried, succession went to his first cousin, the fifth Baron, Michael Richard Hope, who is (As of 2020^[update]) the present holder of the title, and is the eldest son of the Hon. Richard Frederick Hope, who was the youngest son of the first Baron.^{[citation needed]}
