In 1569, Warham St Leger had proposed establishing a small colony in the barony of Kerrycurrihy near Cork Harbour. This soon became a plan to colonize most of Gaelic Munster, but it was rejected by the English privy council. The Munster Plantation of the 1580s was the first mass plantation in Ireland. It was instituted as punishment for the Desmond Rebellions, when the Geraldine Earl of Desmond had rebelled against English interference in Munster. The Desmond dynasty was annihilated in the aftermath of the Second Desmond Rebellion (1579–83) and their estates were confiscated by the Crown. The English authorities took the opportunity to settle the province with colonists from England and Wales, who, it was hoped, would be a bulwark against further rebellions. In 1584, the Surveyor General of Ireland, Sir Valentine Browne and a commission surveyed Munster, to allocate confiscated lands to English Undertakers (wealthy colonists who "undertook" to import tenants from England to work their new lands). The English Undertakers were obligated to develop new towns and provide for the defence of planted districts from attack.
