Medieval Europe saw a complex dance between Church and state power. The Church filled the void left by Rome's fall, assuming governance roles and developing doctrines to justify its authority. This set the stage for centuries of tension with secular rulers.

The struggle played out in battles over appointing bishops, taxing church lands, and defining the limits of papal power. Key conflicts like the Investiture Controversy reshaped European politics, weakening emperors and strengthening popes. The Church's influence touched all aspects of medieval life.
