Answer: The creation of the Protestant movement.
Explanation: The first attempt to reform within the Catholic Church was made by Martin Luther, who resented many of the irregularities, among other things, the possibility of forgiving sins for a certain amount of money. His attempts were severely repressed and a counter-reform of the Catholic Church was instituted, after which Luther was excommunicated from the Church, initiated a Protestant movement and, consequently, the formation of the Lutheran Protestant Church. His work also influenced John Calvin, who also formed his own Church. That all had an impact on political life, the redistribution of political power, because many kings relied on religious leaders to realize this power. With the change in the structure of the population positively determined to the new Protestant Churches, the possibility of exercising political power was also changed. This all again caused many conflicts, wars, etc.
