I have supreme authority I choose bishops I can remove emperors
Charlemagne worked together with the Pope, and in return, the Pope crowned him as emperor. The two lasting effects of this coronations were that it strengthened the power of the Church in Western Europe. Also, it provoked a disagreement which, worsened the growing division between the Eastern and Western churches.
Wait... Are his new rules a direct attack on my power?
Charlemagne believed that god made him emperor in order to do God’s work on Earth and it was the duty of the pope to assist him in that work. The Pope believed that the church had made Charlemagne emperor, and it was the duty of the emperor to assist the Church in doing God’s work. 200 years later, these different views led to a dramatic clash between an emperor and the pope.
HAHAHA... These rules make no sense!
Supreme authority Choose Bishops Remove Emperors
In 1073, Pope Gregory, issued a list of rules declaring his supreme authority over both Church and secular leaders. He also declared that the Pope alone had the power to choose bishops and remove emperors from the throne.
Concordat of Worms
King Henry IV reacted to Gregory’s new list of rules by thinking that this was a direct attack on his own power and rights and the stage was set for a clash of wills between the two men.
The conflict between Pope Gregory and King Henry began when Henry ignored the pope’s rules and named his own bishop. In response, Pope Gregory appointed a rival bishop. Next, Henry tried to remove Gregory as pope. Then Pope Gregory, excommunicated Henry and freed Henry’s subjects form their feudal oaths of loyalty to the emperor. The people across Europe reacted by taking sides.
The conflict ended for Pope Gregory and King Henry, by reaching an agreement called the Concordat of Worms. The Concordat of Worms was an agreement that gave the Church the sole authority to appoint bishops, but it also allowed emperors to give fiefs to bishops in order to win their loyalty. This really wasn’t a success, because emperors and popes continued having conflicts.
