With the partition of Ireland, Northern Ireland received home rule in 1920, though civil unrest meant direct rule was restored in 1972. Support for nationalist parties in Scotland and Wales led to proposals for devolution in the 1970s, though only in the 1990s did devolution happen. Today, Scotland, Wales and Northern Ireland each possess a legislature and executive, with devolution in Northern Ireland being conditional on participation in certain all-Ireland institutions. The British government remains responsible for non-devolved matters and, in the case of Northern Ireland, co-operates with the government of the Republic of Ireland.
