Baldwin III, Count of Guînes

Baldwin (French: Baudouin) was the son of Arnoul II, Count of Guînes and Beatrix of Bourbourg, born at Ardres about 1198.

The period saw multiple invasions of the County, in particular from Renaud I, Count of Dammartin, and heavy damage from Philip II of France, to whom Arnoul was allied.

[3] He was attacked by Ferdinand, Count of Flanders on his release from prison, where he had been for twelve years confined to the Louvre, since 1214 and the Battle of Bouvines where he had opposed Philip II.

[8] Baldwin resented the treatment of his manor of Newington near Hythe in Kent by Hubert de Burgh, who had appropriated it.

[9][10] Baldwin acted as castellan of Monmouth Castle, in the name of Henry III of England, with a force of Flemish mercenaries.

[13] Baldwin's sister Mahaut married Hugo V, count of Saint-Pol, as his second wife, in 1241, having most of the fief of Tourcoing as dowry.
