Matthias played a significant role in the familial opposition of the Habsburgs against his brother Emperor Rudolf II. After gaining power, he showed little political initiative of his own. The course of his politics was determined by Cardinal Melchior Klesl until his fall in 1618. As a consequence of his failed religious and administrative policies, the Bohemian Revolt, the initial theatre of the Thirty Years' War, began during the final year of Matthias' reign.
