Since the Belfast Agreement (sometimes called the Good Friday Agreement) of Friday, 10 April 1998, there has been mainly peace between the two communities in Northern Ireland, the Protestants and Catholics. This agreement was agreed by most of the people in Northern Ireland and the Republic of Ireland, as well as the Irish and British governments. It allows for the self-government of Northern Ireland and greater North-South co-operation and co-operation between Britain and the Republic of Ireland. Additionally, it makes clear the right of the people of Northern Ireland to decide their constitutional future and select whether they are British citizens, Irish citizens or both.
