Schmalkaldic War
Holy Roman Emperor Charles V had won a victory against Protestant forces in the Schmalkaldic War of 1547. Many Protestant princes were unhappy with the religious terms of the Augsburg Interim imposed after this victory. In January 1552, led by Maurice of Saxony, many formed an alliance with Henry II of France at the Treaty of Chambord. In return for French funding and assistance, Henry was promised lands in western Germany. In the ensuing Princes' Revolt, also known as the Second Schmalkaldic War, Charles was driven out of Germany to his ancestral lands in Austria, Innsbruck by the Protestant alliance, while Henry captured the three Rhine Bishoprics of Metz, Verdun and Toul.
