The quarrel between the Popes and the Emperors was never settled, but after a while the two enemies learned to leave each other alone.
In the year 1278, Rudolph of Hapsburg was elected Emperor. He did not take the trouble to go to Rome to be crowned. The Popes did not object and in turn they kept away from Germany. This meant peace but two entire centuries which might have been used for the purpose of internal organisation had been wasted in useless warfare.
