County Cork is the largest and southernmost county in Ireland. Located in the province of Munster, it is named after the city of Cork. It borders four other counties: Kerry to the west, Limerick to the north, Tipperary to the north-east and Waterford to the east. Cork is the largest county in the state by land area.
In 1491 Cork played a part in the English Wars of the Roses when Perkin Warbeck, a pretender to the English throne, landed in the city and tried to recruit support for a plot to overthrow Henry VII of England. The Cork people fought with Perkin because he was French and not English, they were the only county in Ireland to join the fight. The mayor of Cork and several important citizens went with Warbeck to England but when the rebellion collapsed they were all captured and executed. Cork's nickname of the 'rebel city' originates in these events.
