‘pope leo ix’s desire to have more control over the church led to a permanent split in the christian church.

The statement is true. The Pope Leo IX led the Western Church (Roma), and the theological calmness of the West, in contrast to the often violent theological disputes that troubled the Eastern patriarchates, strengthened the position of the Roman popes, who made increasing claims to preeminence. The Eastern Church was led by the patriarch of Constantinople, Michael Cerularius. And both were the responsible of the Schism of 1054, where the Pope Leo IX struck at Michael Cerularius and his followers with an excommunication and the patriarch retaliated with a similar excommunication.

In short, both churches were separated by the desire of Pope Leo IX that Rome should envision the eastern church.

This is true.
