History from Germany

Centuries ago, Germany consisted of many kingdoms and principalities but was united by a common church. The Reformation, led among others by Martin Luther, resulted in schisms within Western Christianity and ultimately in wars between Catholic and Protestant forces. The Peace of Augsburg (1555) temporarily put an end to these conflicts by stipulating that the people of a kingdom or principality were to adhere to the faith of their ruler. Those who believed differently were forced to convert or move to a different region. These provisions applied to Lutherans and Catholics, but not to the followers of Calvin and the Anabaptists, who were thus subject to persecution. The Peace of Augsburg held for over six decades until the outbreak of the Thirty Years War (1618–1648). Peace was regained again by the Peace of Westphalia which affirmed the Peace of Augsburg, this time, however, including the Calvinists. As a result, the German people lived in regional denominational isolation. Confessional diversity within a sovereign land was unthinkable and, driven by the horrors of war, mistrust and loathing between the denominations were rampant. The 19th century saw the advent of other churches and denominations in Germany, among them the Baptist and Methodist as well as old-confessional churches. Their rise was often due to inner church protest movements. As a result, these churches were relatively small in number and mostly disinclined to ecumenical relations.
