My name is Charalamagne and I must rule in a Christian manner.
I pronounce you as "emperor!"
God made me emperor in order to do his work on Earth.
No, the church made you emperor!
Charlemagne was a devout Christian who viewed his victories as proof of God’s blessing. His goal was to improve the Church as a way of thanking God. Charlamagne worked with the pope by giving the pope the safety of his court when people were trying to blind the pope.
NO! That is not fair. I deserve more rights!
I have all the power, for I can elect my own bishops and remove you.
In return, the pope crowned Charlemagne with the title “emperor”. The two lasting effects of this coronation were that it strengthened the Chruch in Western Europe. However, in Eastern Europe, this seemed like an insult to the emperor that the pope could crown an emperor.
I don't care what you say, I can elect my own bishops.
Well I have already elected a bishop.
Charlemagne believed that God had made him emperor in order to do God’s work on Earth. The pope believed the Church had made Charlemagne emperor. 200 years later, these different views led to a dramatic clash between the emperor and the pope. After Charlemagne's empire collapsed, the German lands to the east were divided among a number of dukes.
How about only the church alone can elect a bishop.
In 1073, Pope Gregory issued a list of rules declaring his supreme authority over both Church and secular leaders. He said the pope alone had the power to choose bishops and could remove emperors. Henry IV felt the new rules were a direct attack on his own power and rights. The stage was set for a clash of wills between the two men.
King Henry ignored the pope’s rules and named his own bishop for the city of Milan, Italy. Pope Gregory then appointed a rival bishop. After that, Henry tried to remove Pope Gregory as pope. Then Pope Gregory excommunicated Henry. The people of the clergy and secular rulers took sides as a result.
This conflict finally ended long after both Henry and Gregory died. In 1122, the Church and the Holy Roman Empire reached an agreement called the Concordat of Worms. This gave the Church the sole authority to appoint bishops. This also allowed emperors to give fiefs, or grants of land, to bishops in order to win loyalty. However, popes and rulers continued to have conflicts.
