"In 1530, Charles V, Emperor of the Holy Roman Empire, called together the princes and cities of his german territories in a Diet at Augsburg. He sought unity among them to fend off the attacks of Turkish armies in Eastern Austria. He called upon the Lutheran nobility to explain their religious convictions, with the hope that the controversy swirling around the challange of the Reformation might be resolved. To this end, Philip Melanchthon, a close friend of Martin Luther and a Professor of New Testament at Wittenberg University, was called upon to draft a common confession for the Lutheran Lords and Free Territories. The resulting document, the Augsburg Confession was presented to the emperor on June 25, 1530."
