Answer:
In Europe, during the Middle Ages, most Europeans followed Christianity. Western Europeans belonged to the Roman Catholic Church that was centered in Rome and led by a person called the Pope. People who lived in Eastern Europe during the Middle Ages were also Christian, but they were a part of the Eastern orthodox Church, which was led by someone called a patriarch and the headquarters of this church was located in Constantinople. People who belonged to that church did not follow papel policy because they did not follow the pope.
