Founded in 1971 by Ian Paisley, the Democratic Unionist Party (DUP) is a staunchly unionist political party in Northern Ireland. The party advocates for the maintenance of Northern Ireland's status as part of the United Kingdom, opposing Irish reunification. Known for its strong religious and social conservatism, the DUP has played a significant role in Northern Irish politics, particularly in the context of the region's complex political and religious divisions.
