The High Point of Papal Claims to Be Emperor of the World

A pope by the name of Boniface the 8th, known as a very political man who likely engineered the abdication of the prior pope. Some people say this incidence that I'm going to talk about now is not the high point, but the low point of papal claims to be emperor of the world. So again, this is a battle royal, like Gregory VII and Henry IV, and it has to do with ultimate authority,. Not unlike the Investiture of Controversy, Temporal Power, and Spiritual Power.
