The European wars of religion were waged in Europe during the 16th, 17th and early 18th centuries. Fought after the Protestant Reformation began in 1517, the wars disrupted the religious and political order in the Catholic countries of Europe. Other motives during the wars involved revolt, territorial ambitions and great power conflicts. By the end of the Thirty Years' War (1618–1648), Catholic France had allied with the Protestant forces against the Catholic Habsburg monarchy. The wars were largely ended by the Peace of Westphalia (1648), which established a new political order that is now known as Westphalian sovereignty.
