Labour government, 1974–1979
In March 1976, having just turned sixty years old, Wilson resigned as Prime Minister, ending his leadership of the Labour Party after thirteen years, and a total of nearly eight years as Prime Minister. He was replaced by James Callaghan, who had held senior government positions during both of Wilson's ministries, and had served as a Shadow Cabinet member in the early-1960s.
Wilson Shannon
Shannon was commissioned by President Pierce on August 10, 1855. He took the oath of office on September 7, 1855, and served until June 24, 1856, having been sworn into office a second time on June 13, 1856. He then served from July 7 through August 18, 1856, when he was removed from office by the President. Shannon was known for his Southern sympathies, so much so that he was described by a contemporary as "an extreme Southern man in politics, of the border ruffian type." Shannon frequently utilized federal troops to bring peace to areas of the territory where violence was commonplace. However, the problems of government administration he experienced while Minister to Mexico plagued him in Kansas, and he stumbled into one political crisis after another.
