The DUP opposed the Sunningdale Agreement of 1973. The Agreement was an attempt to resolve the conflict by setting up a new assembly and government for Northern Ireland in which unionists and Irish nationalists would share power. The Agreement also proposed the creation of a Council of Ireland, which would facilitate co-operation between the governments of Northern Ireland and the Republic of Ireland. The DUP won eight seats in the 1973 election to the Assembly. Along with other anti-Agreement unionists, the DUP formed the United Ulster Unionist Council (UUUC) to oppose the Agreement. In the February 1974 UK election, the UUUC won 11 out of 12 Northern Ireland seats, while the pro-Agreement unionists failed to win any. On 15 May 1974, anti-Agreement unionists called a general strike aimed at bringing down the Agreement. The strike coordinating committee included DUP leader Paisley, the other UUUC leaders, and the leaders of the loyalist paramilitary groups. The strike lasted fourteen days and brought Northern Ireland to a standstill. Loyalist paramilitaries helped enforce the strike by blocking roads and intimidating workers. On the third day of the strike, loyalists detonated four car bombs in Dublin and Monaghan, killing 33 civilians. The strike led to the downfall of the Agreement on 28 May.
