The Investiture Controversy
The Investiture Controversy was started by the rivalry of Gregory VII (the king) and Henry IV (the pope), about the authority of who can appoint bishops in 1876, Gregory tried to invade the Henry but died in the process, at the end the king did not get to choose who gets to be bishop, the church was still under the rule of the king, Thomas Bucket was a friend of the king of England(Henry II ) , so when the Archbishop died he was given the title of Archbishop, the only thing is that Thomas was very connected to his role, so when the king(Henry II) invaded he protected the church no matter what, Thomas didn’t die and that that the church and the king got into a peaceful agreement, unfortunately Henry II called some guards to assassinate him, later he admitted that he did it
