Answer:
The pope strengthened his power over the monarchs of Europe.
Step-by-step explanation:
The Crusades was above all a political action. When the Pope orders the Christian to "free the Holy Land from the cursed race", as he named the Muslim, he intended to recover the Church's influence on the East, and overspread the papacy strength over Europe (and far away, why not?). The kingdoms that took part in the Crusades were majority Christians such as France, England, and the states of the Holy Roman Empire.
