The Kingdom of Pamplona, a central Basque realm, later known as Navarre, underwent a process of feudalization and was subject to the influence of its much larger Aragonese, Castilian and French neighbours. Castile deprived Navarre of its coastline by conquering key western territories (1199–1201), leaving the kingdom landlocked. The Basques were ravaged by the War of the Bands, bitter partisan wars between local ruling families. Weakened by the Navarrese civil war, the bulk of the realm eventually fell before the onslaught of the Spanish armies (1512–1524). However, the Navarrese territory north of the Pyrenees remained beyond the reach of an increasingly powerful Spain. Lower Navarre became a province of France in 1620.
