Rome.

In the course of dispute with Pope Gregory VII, who had refused to recognize him as emperor, Henry III of Germany laid siege to Rome in 1082. After two interruptions to the siege, the city was finally surrendered to him by the Roman nobles, March, 1084. Gregory was deposed, and the anti-Pope Clement III set upon the pontifical throne, Henry at the same time assuming the Imperial purple.
