The king's attempts to discard the constitution led to another military revolt (1862) and to his deposition. In 1863 the Greeks chose a Danish prince to become their king as George I.

Otto hastened back to Rome (963), deposed John, and installed a new pope, Leo VIII. The Romans, seeing all independence lost, rose in 964 and restored John, but John died the same year and Otto reinstated Leo.
