I alone have the power to remove whom ever I want from the throne, choose bishops, and have the authority over both Church and secular.
Who does Pope Gregory think he is making new rules assuming that he's the ruler.
You have been excommunicated from the church for ever.
That's fine Pope I will be back to take my revenge.
Pope Gregory VII issuing a list of rules in which he believes that the Pope should have. First, he claimed his supreme authority over both the Church and the secular. Next, he declared that the Pope alone had the power to choose bishops and even declared to have the power to remove emperors from the throne.
Forgive me Pope for my sins. I hope that you can undo my excommunication.
Humm... I forgive you Henry
King IV the Roman emperor had his own opinion over Pope Gregory's new rules. He found his statement an insult or attack towards his ruling. The clash between who had authority over what had finally started.
Does the Church agree to have a truce and respect each others decisions.
We will respect emperors decisions as long as they respect ours.
Henry, first, ignored the Pope's rules and named his own bishop in Italy. The Pope decided he would do the same by electing his own bishop and excommunicating Henry. Next, Henry tried to remove Gregory as Pope. Finally, the Pope freed Henry's subjects from their feudal oaths of loyalty towards the emperor.
I can not believe that after all of these years of back and forth disagreements the emperor and the church can't seem to get along.
Henry went to go visit the Pope in an Italian castle to end his excommunication. He stood outside in the snow for three days before the Pope saw him. Although the Pope forgave him, their conflict continued. In fact, Henry took revenge by marching his army to Rome and forcing the Pope from office.
Long after Henry and the Pope died the power struggle continued. Until about 1122, the Church and the Holy Roman Empire reached an agreement called the Concordat of Worms which would help them end this battle.
The Concordat of Worms gave the Church the authority to appoint bishops. Although, it allowed emperors to grief to bishops in order to win their loyalty. Popes and rulers continued to have conflict despite their agreement.
