I want to make the church better! I would like to order priests, monks, and nuns please.
I now declare Charlemagne as emperor!
The Pope will crown the emperor!
No they shouldn't!
Charlemagne was a dedicated Christian ruler. His goal was to improve the church to thank God for the blessings he provided Charlemagne. He ordered priests, monks, and nuns to live strictly by Church rules. He tried to rule in a very Christian way.
I feel so threatened by the Pope!
Charlemagne traveled to Rome to support the pope and in return, Pope Leo crowned Charlemagne an emperor. Becoming an emperor had strengthened the power of the western church. In addition, the emperor declared that only the pope can only crown an emperor.
Do I care? I am the king and I shall make the decisions myself!
Didn't the Pope declare that only popes can appoint bishops?
However, Eastern Europe disagreed with this. They argued that the pope shouldn't be held with that authority. This turned into a huge clash between who should crown the emperor. These differences led to the great schism where the two churches split.
Okay, fine deal!
Stop being the pope!
Over 200 years have passed and the conflict still continued. A powerful Pope named Pope Gregory declared popes alone can hold supreme authority over everyone, choose bishops, and have the power to remove rulers from their throne. King Henry felt threatened that his authority and power will be lost forever.
Conflict soon arose as Henry disobeyed the rules of the pope as he names his own bishop. Pope Gregory responded as appointing a rival bishop. More conflicts occurred when Henry attempted to remove Gregory as pope. However, in return, King Henry was excommunicated. People all over Europe took sides and wondered who would overtake the clash between the two.
The conflict between King Henry and Pope Gregory ended as King Henry marched his army to Rome to force the Pope from office. From preventing the clashes again, the Concordat of Worm. It was an agreement that the Church was the sole authority to appoint bishops and had many more rights. Despite the agreement, the popes and rulers still fought.
