List of Viscounts of Béarn
House of Gascony
Until 1251, probably all counts of Gascony descended from the House Gascony, head of the Duchy of Gascony.
Sister of the predecessor, married the Catalan Guilhem de Montcada. During their joint rule, other rulers appeared contesting their rule, or were merely legendary:
1412–1436 : John I (son of, also count of Foix, viscount of Villemur and count of Bigorre)
1436–1472 : Gaston XI (son of, also count of Foix, viscount of Nébouzan and count of Bigorre, married Eleanor of Navarre, queen of Navarre) (References to "Gaston of Bearn" in history texts often refer to him)
In 1512 Ferdinand II of Aragon conquered the better part of the kingdom of Navarre, leaving the kingdom with only the small section it held north of the Pyrenees.
