Henry IV. (10501106)

Henry IV., Emperor of the Holy Roman Empire, son of preceding; his reign is memorable as witnessing the first open claim on the part of the Papal power to have dominion over the crowned heads of Europe; Henry's attempt to depose Gregory VII. was boldly met by a declaration of excommunication; Henry was forced to do penance and to receive his crown afresh from the Pope; but the struggle broke out anew; Clement III. was put up in opposition, and the contest raged with varying success till the deposition of Henry by his ungrateful son (10501106).
