 The violent death of Sancho II, who had no descendants, allowed Alfonso VI to reclaim his throne as well as Sancho's and Garcia's original inheritances of Castile and Galicia, respectively.Although Rodrigo Díaz de Vivar (El Cid), the standard-bearer and confidant of King Sancho II, was present at the siege of Zamora, the role he played in this event is not known.Neither can Sancho II's death be blamed on Alfonso VI, who, when his brother was killed, was in exile far from the events.
