O'Doherty's Rebellion took place in 1608 when the landowner Sir Cahir O'Doherty began an uprising against the authorities in the north-west of Ireland. O'Doherty had been a long-standing supporter of the Crown, but having been angered at his treatment by local officials he launched an attack on Derry, burning the town. O'Doherty may have hoped to negotiate a settlement with the government, but after his death in a skirmish at Kilmacrennan the rebellion collapsed with the last survivors being besieged on Tory Island.
