Investiture Controversy

Ruler Otto ruled the church during his reign by dedicating to his bishop and monastery prince and his agent (425). However, the resurrection of the church began with the weakness of the German empire in the 11th century (425). During this period, the Church proclaimed independence from the government by adopting the reform movement "Clooney Reform Movement" (425). The reform established at the Cluny monastery in France is aimed at "releasing the church from secular political influence and control" (425).

Investment controversy or general investment controversy is the most serious confrontation between secular power and religious power in medieval Europe. It came from a controversy about who appointed a bishop (appointment) between the Holy Roman Emperor Henry IV and Pope Gregory VII in the eleventh century. The conclusion of a non professional mission may weaken the nobility's ambitions which will benefit the empire's power and the reform of the Church. Bishop gained income from the property that came with his bishop. The nobility who owns the land (territory) inherits the land in the family. However, since the bishop does not have legitimate children, when the bishop dies, the king has the right to appoint a successor. Therefore, the King can hardly prevent aristocrats from acquiring a strong field by inheritance and dynasty marriage, but the king can carefully rule the land in the field of bishop.

Certified disputes are one of the most important conflicts between the church and the state. In addition to seeking the bishop's appointment, the pope also sought the elimination of the emperor. The Pope said, "He can either abolish or restore the bishop alone" and "He can make him abolish the emperor." Pope Gregory VIII influenced the influence of the Church clergy's emperor's choice I hope to end it. Pope Gregory, in response to his order for non-expert permission, tried to establish the hegemony of the Pope at the expense of King Henry VI. Historian Brian Tierney says, "To ban non-professional permission is the essence of Gregory's plan, which is not a requirement that the king can accept at that time." The essence of Gregory Its procedure can be said that continuation of authorization by non-experts is the essence of the Otto system. (Article 267)
