Hayes promptly made good on the secret pledges made during the electoral dispute to withdraw federal troops from states still under military occupation
The holy roman emperor (Henry IV) wanted to make the church independent from secular rulers so he banned the practice of Lay Investiture. The pope (Gregory VII) excommunicated him and went to find a new emperor when Henry IV confessed to him he was a sinner and Gregory forgave him. But Henry was so butt hurt about it that he sent to roman military to kill the pope.
