Northern Ireland law
Northern Ireland law refers to the legal system of statute and common law operating in Northern Ireland since the partition of Ireland established Northern Ireland as a separate jurisdiction within the United Kingdom in 1921.
For the purposes of private international law the United Kingdom is divided into three distinct legal jurisdictions:Northern Ireland is a common law jurisdiction. Although its common law is similar to that in England and Wales, and partially derives from the same sources, there are some important differences in law and procedure between Northern Ireland and England and Wales. While influenced by English law, the Northern Ireland legal system is distinctive for a number of reasons: it has roots in Irish common law prior to Irish independence in 1921; following Irish independence, Northern Ireland became a devolved jurisdiction within the United Kingdom.
Ireland–United States relations
The Irish War of Independence ultimately ended with the Anglo-Irish Treaty, which confirmed the partition of Ireland into the Irish Free State and Northern Ireland, the latter of which opted to remain a part of the United Kingdom. The Irish Free State quickly fell into the Irish Civil War between Pro-Treaty Forces who supported independence via partition and Anti-Treaty Forces who opposed partition and wanted independence for the entire island of Ireland. Pro-Treaty Forces won the Irish Civil War in 1923, and the following year the United States recognized the Irish Free State and established diplomatic relations with it. The Irish Free State was succeeded by the new state of Ireland in 1937, and formally declared itself a republic in 1949.
