Holy Roman Empire Ferdinand II of Bohemia tried to restrict his subject’s religious activities, which caused the Protestants to revolt.
The people thought that the King had to much power and wanted him out of power.
One of the other reasons as to why there was a 30 year war was because of money. Money= Power too. Everyone wanted more money.
WE DON'T WANT YOU CATHOLICS!
THe war had different phases. They were the (not in order in the picture sorry) Bohemian, than the Danish, the Swedish, and finally the French.
During the last years of the war, they were just fighting, and hadn’t even remembered why! They all gathered up and made a treaty: The Peace of Westphalia. This treaty weakened the Holy Roman Empire, and left France as the most powerful country in Western Europe. The Protestants one this one!
After the war, the influence and power of the Catholics became very little. People did not want the Catholics.
