James Craig, 1st Viscount Craigavon, Irish captain and politician, 1st Prime Minister of Northern Ireland (died 1940)

James Craig, 1st Viscount Craigavon, PC, PC (NI), DL, was a leading Irish unionist and a key architect of Northern Ireland as a devolved region within the United Kingdom. During the Home Rule Crisis of 1912–14, he defied the British government in preparing an armed resistance in Ulster to an all-Ireland parliament. He accepted partition as a final settlement, securing the opt out of six Ulster counties from the dominion statehood accorded Ireland under the terms of the 1921 Anglo-Irish Treaty. From then until his death in 1940, he led the Ulster Unionist Party and served Northern Ireland as its first Prime Minister. He publicly characterised his administration as a "Protestant" counterpart to the "Catholic state" nationalists had established in the south. Craig was created a baronet in 1918 and raised to the Peerage in 1927.

The prime minister of Northern Ireland was the head of the Government of Northern Ireland between 1921 and 1972. No such office was provided for in the Government of Ireland Act 1920; however, the Lord Lieutenant of Ireland, as with governors-general in other Westminster systems such as in Canada, chose to appoint someone to head the executive even though no such post existed in statute law. The office-holder assumed the title prime minister to draw parallels with the prime minister of the United Kingdom. On the advice of the new prime minister, the lord lieutenant then created the Department of the Prime Minister. The office of Prime Minister of Northern Ireland was suspended in 1972 and then abolished in 1973, along with the contemporary government, when direct rule of Northern Ireland was transferred to London.
