Spanish conquest of Iberian Navarre
The Spanish conquest of the Iberian part of Navarre was initiated by Ferdinand II of Aragon and completed by his grandson and successor Charles V in a series of military campaigns lasting from 1512 to 1524. Ferdinand was both the king of Aragon and regent of Castile in 1512. When Pope Julius II declared a Holy League against France in late 1511, Navarre attempted to remain neutral. Ferdinand used this as an excuse to attack Navarre, conquering it while its potential protector, France, was beset by England, Venice, and Ferdinand's own Italian armies.
