Sligo’s French Siege Gun
Archived: 18 October 2026
Abstract
In 1516, Ireland was governed through overlapping royal, Gaelic and urban powers. As Henry VIII’s deputy, Kildare led a coalition that captured Leap Castle, secured hostages and imposed authority in the midlands. In the north-west, Manus O’Donnell obtained French-linked artillery after a pilgrim’s visit to Lough Derg, used it to take Sligo Castle, and later negotiated peace with O’Neill under Dublin’s mediation. Kildare’s Dublin parliament addressed markets, ports, taxation and defence. Religious life, travel and scholarship remained vital: friars drowned on Lough Erne, the Book of Fenagh was completed, and Desmond’s Gaelic lord died amid continuing regional warfare and connections.
