YOU ARE NOW OFFICIALLY EXCOMMUNICATED FROM THE CHURCH!!!
In 1073, a new pope came around. He was pope Gregory VII, and he had lots of plans for he would head the church. The current emperor at the time was King Henry IV, who was also hungry for power.
You are officially forgiven and allowed back at church.
Pope Gregory VII made a set of rules, one stating that he could remove anyone from their position in government, including the Emperor. King Henry IV was stunned and outraged. This started the conflict between popes and rulers.
We have come to an agreement!
We call it the Concordat of Worms!
Since King Henry refused the Pope's rules, the Pope decided to excommunicate him from the church. This means he could not go to church. King Henry was very upset because he would not only be banned from church, but he would lose the support of his people.
I SHOULD BE ABLE TO APPOINT BISHOPS!!!
NO YOU SHOULD NOT!!!
A few years later, the Pope officially forgave King Henry and let him back in the church. Only a year later, he was excommunicated again. He once again disobeyed the Pope's rules.
Long after Henry and Gregory died, the two sides made an agreement called the Concordat of Worms. It states that only the Pope can appoint bishops. However, the King can approve or disapprove of his decision.
The agreement was not a success in the long run. It may have worked for a little while, but conflicts continued after this agreement. The emperors and Popes continued to argue over who should appoint bishops.
