Flight of the Earls
The Flight of the Earls (Irish: Imeacht na nIarlaí) took place on 14 September [O.S. 4 September] 1607, when Irish earls Hugh O'Neill, Earl of Tyrone, and Rory O'Donnell, Earl of Tyrconnell, permanently departed Rathmullan in Ireland for Catholic Europe during a period of extreme political tension with the English Crown. The Flight's exact motivation is unclear and the subject of debate.
