How are monarchs church and crusades related?

Monarchs, the church, and the Crusades were intertwined in medieval Europe. Monarchs often worked closely with the church to validate their rule and gain divine support. The Crusades were military campaigns sanctioned by the church, led by monarchs, with the goal of reclaiming the Holy Land from Muslim control. This collaboration between all three entities shaped the power dynamics and religious landscape of Europe during this period.
