It reflects the struggle for control between church authorities and temporal rulers during a time when religion played a central role in societal governance.
Christendom: Christendom refers to the collective body of Christians and Christian institutions in Europe during the Middle Ages, particularly as they related to the political and cultural landscape. This term embodies the unity of the church and state, where Christianity was not just a faith but a defining element of European identity, influencing laws, governance, and social norms throughout medieval society.
Concordat of Worms: The Concordat of Worms was a pivotal agreement reached in 1122 that resolved the Investiture Controversy between the Pope and the Holy Roman Emperor.
