Partition of Ireland
The partition of Ireland () divided the island of Ireland into two distinct jurisdictions, Northern Ireland and Southern Ireland. It took place on 3 May 1921 under the Government of Ireland Act 1920. Today the former is still known as Northern Ireland and forms part of the United Kingdom, while the latter is now a sovereign state also named Ireland and sometimes called the Republic of Ireland.
Privy Council of Northern Ireland
The Council was created in 1922 as a result of the division of Ireland into the Irish Free State and Northern Ireland. The latter remained part of the United Kingdom albeit with its own parliament. The previous Privy Council of Ireland was obsolete although never formally abolished in British law.
