Explanation:

IN medieval Europe, all of the kings and queens from the different monarchies needed approval from the Vatican, this empowered the Vatican and the pope, and gave the Catholic church a sphere of influence over all Europe that made them a unifying force, all monarchs had interests invested in the Vatican, with bishops and archbishops from their families around the political sphere of power at the Vatican. This helped unify Europe under the influence of the catholic church, and since Kings were monarchs sent by God to rule their people, they gained validation from the church by accepting it and embracing it.
