 Together with the formation of the Schmalkaldic League in 1531, this struggle with the Ottomans caused Ferdinand to grant the Nuremberg Religious Peace.As long as he hoped for a favorable response from his humiliating overtures to Suleiman, Ferdinand was not inclined to grant the peace which the Protestants demanded at the Diet of Regensburg which met in April 1532.But as the army of Suleiman drew nearer he yielded and on July 23, 1532 the peace was concluded at Nuremberg where the final deliberations took place.
