Step-by-step explanation:
The push for the Crusades came when the Byzantine emperor asked for aid.
The Crusades were a series of holy wars fought between Christians and Muslims during the medieval period. The push for the Crusades began when the Byzantine emperor Alexios I Comnenus asked for aid from Pope Urban II to help defend against the Seljuk Turks. This ultimately led to the First Crusade in 1096. The Byzantine emperor's request for assistance was a significant factor in motivating European Christians to participate in the Crusades.
