March 20th , 1914
The Curragh incident of 20 March 1914, sometimes known as the Curragh mutiny, occurred in the Curragh, County Kildare, Ireland. The Curragh Camp was then the main base for the British Army in Ireland, which at the time still formed part of the United Kingdom of Great Britain and Ireland. Ireland was scheduled to receive a measure of devolved government, which included Ulster, later in the year. The incident is important in 20th-century Irish history, and is notable for being one of the few occasions since the English Civil War in which elements of the British military openly intervened in politics. It is widely thought of as a mutiny, though no orders actually given were disobeyed.
