All i want to do is create a successful Christian Empire!
Hey Charlemagne, lets make a deal.
The church made Charlemagne emperor.
God made me emperor in order to go God's work on Earth.
Once upon a time, there was a large kingdom ruled by Charlemagne. Charlemagne wanted to create a successful Christian Empire. For this to happen, he had to work together with Pope Leo.
I am Pope Gregory. I am kicking you out of the throne, because I can!
While working with Charlemagne, the Pope had to reward him. In 799 Pope Leo asked Charlemagne for protection. Charlemagne agreed and was rewarded by being crowned Holy Roman Emperor by Pope Leo. As a result the Pope won power to crown the emperor which angered the Byzantine emperor.
Listen to me!
No. I am ignoring you!
Even though Charlemagne and the Pope had a deal that benefited both of them, they still disagreed over something. Charlemagne believed that God had made him emperor in order to do God's work on Earth. On the other hand, Pope Leo believed that the church made Charlemagne emperor. But around 200 years later, after Charlemagnes coronation, these different views led to a dramatic clash between an emperor and Pope.
Please, forgive me!
In 1073 Pope Gregory became Pope. Pope Gregory declared the Pope had the power to choose bishops. He also stated he had the power to remove emperors from the thrown. The new rules were a attack at Henry IV's rules and rights. The fight was set between the two clash of men. Henry IV ignored the Popes new rules and named his own bishop for the city of Milan. Then Henry tried to remove Gregory from the thrown.
Pope Gregory and King Henrys conflict started when Henry ignored the Popes new rules, and assigned a bishop to the city of Milan. After that, Pope Gregory appointed a rival bishop. Because of that, Henry tried to remove Gregory as Pope. In response, Gregory then excommunicated Henry. Members of the clergy across Europe took sides. In order to end this excommunication, Henry stood in the snow outside the castle for three days begging for forgiveness.
The conflict between Gregory and Henry ended with Henry standing outside the castle for three days begging for forgiveness. Later, in 1122, the church and Holy Roman empire came to a agreement called Concordat of Worms. The Concordat of Worms was a agreement that gave the church all authority to assign bishops. But it also let emperors give fiefs to bishops in order to win loyalty. This agreement although sounding successful, but popes and rulers continued to have conflict.
