 This changed in 1076, when Sancho IV of Navarre was murdered by his own siblings, thus prompting a succession crisis in this neighboring kingdom that represented Aragon's nominal overlord.At first, the murdered king's young son, García, who had fled to Castile, was recognized as titular king by Alfonso VI, while Sancho Ramírez recruited to his side noblemen of Navarre who resented their kingdom falling under Alfonso's influence.The crisis was resolved by partition.
