What was the thirty years war and how did it change how people viewed different religions?

The Thirty Years War was a 17th century religious conflict initially in Central Europe. The war lasted from 1618 to 1648, starting as a battle among the catholics and the Protestants that formed the Holy Roman Empire. The war brought famine and disease in Europe.
