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.
Military history of Ireland
Until 1922 secret societies, popular risings and guerilla warfare came in sporadic outbreaks in attempts to end the 1801 union of Ireland and Great Britain. Between 1919–1922 the War of Independence brought the negotiation of the Anglo-Irish Treaty and the majority of Ireland seceded from the United Kingdom to form an independent state, which immediately fell into a civil war between opposing republican factions. The northern portion of the country would form Northern Ireland becoming an autonomous part of the United Kingdom.
