On 7 December 1921 the Irish Free State Treaty was signed between Ireland and Britain, awarding Ireland home rule following decades of fighting and insurrection.

On the day it was signed the treaty referred to Ireland in its entirety, but Northern Ireland soon opted out of the new state and stayed under British control.

The treaty came into effect exactly a year after it was signed and the British military withdrew.
