Charles V tried to stop the spread of [[Lutheranism]]. In 1544, Charles V sent armies against the German princes, but the [[Peace of Augsburg]] in 1555 gave each German ruler the right to choose the religion for his state. The princes in southern Germany selected Roman Catholicism, but the princes in northern Germany chose Lutheranism. After [[World War II]], when Germany split into West and East Germany, the West German part contained the predominantly Roman Catholic regions and the East German part consisted of the mostly Lutheran regions. | Charles V tried to stop the spread of [[Lutheranism]].
