Overview
Terence Marne O'Neill, Baron O'Neill of the Maine, PC (NI) (10 September 1914 – 12 June 1990), was the fourth prime minister of Northern Ireland and leader (1963–1969) of the Ulster Unionist Party (UUP). A moderate unionist, who sought to reconcile the sectarian divisions in Northern Ireland society, he was a member of the Parliament of Northern Ireland for the Bannside constituency from 1946 until his resignation in January 1970; his successor in the House of Commons of Northern Ireland was Ian Paisley, while control of the UUP also passed to more hard-line elements.
Background
Terence O'Neill was born on 10 September 1914 at 29 Ennismore Gardens, Hyde Park, London.
O'Neill grew up in London and was educated at West Downs School, Winchester and Eton College. He spent summer holidays in Ulster. Following school he spent a year in France and Germany and then worked in the City of London and Australia. In May 1940 he received a commission at the Royal Military College, Sandhurst, and went on to serve in the 6th Guards Tank Brigade during the Second World War, in which both of his brothers died. Like many other unionist politicians, the rank he held during the war followed him into his political career, hence "Captain" Terence O'Neill.
