Ian Paisley, Northern Irish evangelical pastor (Free Presbyterian Church) and politician, 2nd First Minister of Northern Ireland (born 1926)

Ian Richard Kyle Paisley, Baron Bannside, was a loyalist politician and Protestant religious leader from Northern Ireland who served as leader of the Democratic Unionist Party (DUP) from 1971 to 2008 and First Minister of Northern Ireland from 2007 to 2008.

The Free Presbyterian Church of Ulster is a Calvinist denomination founded by Ian Paisley in 1951. Doctrinally, the church describes itself as fundamentalist, evangelical, and separatist, and is part of the reformed fundamentalist movement. Most of its members live in Northern Ireland, where the church is headquartered, and in County Donegal. The church has additional congregations in the Republic of Ireland, Great Britain and Australia, and a sister denomination in North America, the Free Presbyterian Church of North America, which has congregations in Canada and the United States. It also has a sister denomination in Nepal which was formed from the Nepal mission to the Unreached in November 2013.

The First Minister and Deputy First Minister of Northern Ireland are the joint heads of government of Northern Ireland, leading the Northern Ireland Executive and with overall responsibility for the running of the Executive Office. Despite the titles of the two offices, the two positions have the same governmental power, resulting in a duumvirate; the deputy first minister is not subordinate to the first minister. Created under the terms of the 1998 Good Friday Agreement, both were initially nominated and appointed by members of the Northern Ireland Assembly on a joint ticket by a cross-community vote, under consociational principles. That process was changed following the 2006 St Andrews Agreement, such that the first minister now is nominated by the largest party overall, and the deputy first minister is nominated by the largest party from the next largest community block.
