One method the Church used to increase its secular authority was by establishing a close alliance with secular rulers. This allowed the Church to wield political power and influence over important decisions. Additionally, the Church claimed divine authority, asserting that it held sway over the spiritual and temporal affairs of individuals. Lastly, the Church used its vast wealth, acquired through tithes and donations, to build grand cathedrals and offer financial support to secular rulers, further solidifying its authority.
