A colonization of Ulster had been proposed since the end of the Nine Years' War. The original proposals were smaller, involving planting settlers around key military posts and on church land, and would have included large land grants to native Irish lords who sided with the English during the war, such as Niall Garve O'Donnell. However, in 1608 Sir Cahir O'Doherty of Inishowen launched a rebellion, capturing and burning the town of Derry. The brief rebellion was ended by Sir Richard Wingfield at the Battle of Kilmacrennan. The rebellion prompted Arthur Chichester, the Lord Deputy of Ireland, to plan a much bigger plantation and to expropriate the legal titles of all native landowners in the province. John Davies, the Attorney-General for Ireland, used the law as a tool of conquest and colonization. Before the Flight of the Earls, the English administration had sought to minimize the personal estates of the chieftains, but now they treated the chieftains as sole owners of their whole territories, so that all the land could be confiscated. Most of this land was deemed to be forfeited (or escheated) to the Crown because the chieftains were declared to be attainted. English judges had also declared that titles to land held under gavelkind, the native Irish custom of inheriting land, had no standing under English law. Davies used this as a means to confiscate land, when other means failed.
