Northern Ireland is situated on the northeast of Ireland and is one of the four countries that make up the United Kingdom. It shares a border with the Republic of Ireland to the south and west. The population of Northern Ireland was 1.685 million at the 2001 census and is predominantly white and Christian. The history of Northern Ireland has been complex, with conflict and violence between 1969-2004 resulting in over 3,000 deaths. While religion separated the two communities, the underlying cause of the conflict was power and control over the region.
