In 1512, the Crown of Castile and Crown of Aragon invaded and occupied the Kingdom of Navarre. A Franco-Navarrese coalition repeatedly attempted to reclaim it; in 1521 they succeeded in capturing the strategically vital border fortress of Fuenterrabía, prompting Spain to respond militarily.
A Spanish army besieged Fuenterrabía from 1523 to 1524 with the aim of retaking the town and fortress, which sat at the mouth of the Bidasoa River on a hill fortified by thick walls, mountains, and the sea, and had been held by Franco-Navarrese forces since their 1521 incursion.
The siege formed part of the broader contest between Charles V and Francis I over the Pyrenean borderlands. By 1517 the territorial rights of the region had been partially defined by treaty between Spain and France, leaving Navarre divided, and the control of Fuenterrabía remained a focal point of their rivalry.
