Question

what tools did the medieval church use to enforce its authority over european rulers? (1 point)
royal marriage alliances
military campaigns
interdict
economic sanctions

Explanation:

The medieval Church used the interdict as a powerful tool. An interdict was a form of ecclesiastical censure that could be placed on a region or ruler. It restricted the administration of sacraments and other religious services in the affected area, putting pressure on rulers to comply with the Church's demands due to the strong religious beliefs of the people. Royal marriage alliances were more about political - family connections, military campaigns were not a typical Church - used tool for this purpose, and economic sanctions were not a main tool of the medieval Church in this context.

Answer:

C. Interdict
