Explanation:

Now it would only take a spark to set off the war. The spark came in 1618. The future holy roman emperor Ferdinand II, was head of the Hapsburg family. He ruled the Czech kingdom of Bohemia but was not trusted by his people. The protestants didn't trust him because he was a catholic and a foreigner. He closed some protestant churches which caused a revolt and when he tried to crush the revolt several German protestant princes challenged him, beginning the thirty years war. The thirty years war was a conflict over religion and territory and for power among European ruling families. The war ca be divided into two main phases: the phase of the Hapsburg triumphs and the phase of the Hapsburg defeats. The war lasted from 1618 to1648
