He is most famous for the role he played in the Investiture Controversy with Henry IV.
Emperor Henry IV called a meeting with the bishops and with their approval he sent Pope Gregory VII a letter ordering him to step down. Gregory sent a letter back excommunicating Henry IV. Henry asked for forgiveness to no avail. In January 1077, Henry went to Canossa where Gregory was visiting still trying to get forgiveness. After making Henry wait three days out in the snow, Pope Gregory finally ended his excommunication.
It's because Henry's nobles supported Gregory, and the reason why Henry begged the Pope was because he said the Pope had no real authority.
Roman Catholic AnswerOne of the biggest things to happen during the reign of Pope Gregory VII was the investiture controversy. The issue was who had the right to appoint bishops, and the Popes have always held that as their right. King Henry IV, the Holy Roman Emperor, was the primary target of Pope St. Gregory VII, but the popes have always said that it was their right, alone, to appoint new bishops, Henry disagree. In short, Pope St. Gregory VII said that kings could no longer appoint bishops.
