Former kingdom comprising the Spanish province of Navarre and part of what is now the French departement of Basses-Pyrenees. It resisted the conquest of the Moors and was independent until it became French 1284 on the marriage of Philip IV to the heiress of Navarre. In 1479 Ferdinand of Aragon annexed Spanish Navarre, with French Navarre going to Catherine of Foix (1483-1512), who kept the royal title. Her grandson became Henry IV of France, and Navarre was absorbed in the French crown lands 1620.
