In depth
The Good Friday Agreement (1998), formally the Belfast Good Friday Agreement, is the peace accord that ended the Troubles in Northern Ireland. Among its provisions, the Agreement confirms the right of people in Northern Ireland to identify as Irish, British, or both, and to hold citizenship accordingly.
For CBD purposes, this means an ancestor born in Belfast, Derry, or anywhere in Northern Ireland qualifies you for the Irish Foreign Births Register, with the same rights as an ancestor born in Dublin or Cork.
The Good Friday Agreement is recognized in both Irish and British law, and is protected by an international treaty between the UK and Ireland.
