The Catholic Church played a significant role in medieval European politics, serving as a central authority amid the feudal system. It wielded considerable power, influencing kings and rulers through spiritual and temporal means. The Church owned vast lands, collected taxes, and provided social services, reinforcing its wealth and authority. Moreover, it often intervened in political matters, such as excommunications, which could destabilize monarchies. The Church also fostered the spread of Christianity, shaping the moral and ethical frameworks of medieval society and establishing itself as an essential player in European governance.
