Augsburg Religion Day, celebrated annually on June 25, is set in memory of an important historical event. On this day, Lutheranism received the status of an official religion in Germany, and Protestantism won the right to exist in it.
Augsburg confession ( Confessio Augustana ) – the earliest of official Protestant symbols of faith, still being a religious norm for Lutherans, these are the main points of faith of the first Lutheran, which in 1530 was composed of Lutheran theologians Philip Melanchton ( Philipp Melanchton, 1497 — 1560 ), the closest associate of Martin Luther. They were presented on June 25, 1530 to the Augsburg Reichstag. However, the princes, who remained faithful to Catholicism, refused to accept a new confession. Taking advantage of this, the Emperor of the Holy Roman Empire, Charles V, by his power suspended the work of the Reichstag and declared war on the new movement.
In response, the Protestants formed the Shmalkalden League — a kind of defensive union. After several attempts to find a compromise between Catholics and Protestants, the tragic Shmalkalden war broke out in 1546.
In the end, on September 25, 1555, between the head of the Holy Roman Empire of the German nation, Charles V, and the rulers of the Protestant lands, who achieved equal rights with the Catholic princes, the Augsburg religious world was concluded, who legitimized Protestantism. The contract was confirmed by a papal decision.
Thus, Lutheranism received the status of a state religion.
