 With the assassination of Sancho IV, Navarre was partitioned by his cousins Alfonso VI of Castile and Sancho Ramírez of Aragón, and the latter made king, leading to more than half a century of Aragonese control.The death of Alfonso led to a succession crisis in Aragón and the nobles of Navarre took advantage to reestablish an independent monarchy, crowning a grandnephew (through an illegitimate brother) of the assassinated Sancho IV.The death of Sancho VII, the last of the Jiménez kings, led to the crown of Navarre being inherited by the son of his sister Blanche, Countess of Champagne, she having been regent during much of her brother's reign.
