Mountjoy's long-term successor in Ireland was Sir Arthur Chichester. Ireland remained in a state of some tension, with a number of disgruntled Gaelic Irish allies of the Crown angered by Mountjoy's generous terms to the Earls of Tyrone and Tyrconnell which meant land that had been promised to them had now been restored to the earls. In 1607, a year after Mountjoy's death, the flight of the Earls took place. The following year a former government ally Sir Cahir O'Doherty attacked and burned Derry, launching O'Doherty's Rebellion. The flight and the rebellion led to the Plantation of Ulster, something that had not been envisaged by Mountjoy when he had made peace in 1603.
