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.
