How did the power of the catholic church expand in the middle ages? europe was unified under the idea that people must convert to christianity. the church assumed governmental duties and created a church hierarchy. the pope had the same power the roman emperor once had. the people began to elect their priests, bishops, and cardinals.

The Catholic Church became a powerful political and social establishment just after fall of the Western Roman Empire in 476, and its impact gradually extended.

Explanation:

•During the collapse and fall of the Western Roman Empire, and throughout the Middle Ages, the office of papal not only grew in power over the entire Christian Church, but also rivalled that of Europe's secular rulers. During the early centuries of Christianity, Rome grew in importance as a spiritual centre, giving the bishop of Rome (the pope) increased influence over the entire church and ushering in the era of papal dominance.

•When Catholicism became the official religion of the Roman Empire in 380, the power of the pope increased, although he was still subordinate to the emperor.

The church assumed governmental duties and created a church hierarchy.

After the collapse of the Roman Empire, most social institutions were lost. The only European institution to rise from this was the Catholic Church, and because of this, it was able to exert its power over most of Europe unchallenged.

During the High Middle Ages, the Catholic Church became organized into an elaborate hierarchy. It established the supreme power of its leader, the Pope. It also adopted most of the duties that we now associate with government. This model was not challenged until the late medieval period.
