What resulted the relationship between pope Gregory vii and Henry iv of Germany?

The relationship between Pope Gregory VII and Henry IV of Germany was marked by intense conflict over the authority of the church versus the monarchy, culminating in the Investiture Controversy. Gregory VII's assertion of papal supremacy and his excommunication of Henry IV in 1076 led to a significant power struggle. Henry's subsequent penance at Canossa in 1077 temporarily reconciled them, but tensions persisted, ultimately resulting in a weakening of royal authority in Germany and reinforcing papal power. This conflict laid the groundwork for ongoing disputes between church and state in medieval Europe.
