Question: why were the pope and the emperor willing to accept the terms of the concordat of worms

title: Concordat of Worms
text: In the period immediately after 1000 , two figures appeared to lead Western Christendom , the pope and the Holy Roman Emperor . Antagonism between the two dominated the next century . After the death of Pope Sylvester II in 1003 , the papacy fell under the influence of the nobility in Latium , and then after 1046 , under the influence of the German emperors . The reality for the west in the Middle Ages was not only the fact that government was split up into small particles but also the fact that vertical and horizontal powers were entangled . People in the Middle Ages did not always know to which of the many lords , the Church and the individual churches , the towns , princes , and kings , they were subordinate . This can be observed in the complexity even at the administrative and judicial level in the jurisdictional conflicts that fill mediaeval history .
