start. George von Carlowitz, one of the new confidants of the Duke, advised Maurice (in order to prevent a war with Emperor Charles V and his brother Ferdinand, at the same time King of the Romans and his neighbour as King of Bohemia) not to endanger the survival of the Protestant Movement. Thus he participated in the emperor's army in the war against the forces of the Sultan Suleiman the Magnificent of the Ottoman Empire (1542), Duke William of Jülich-Cleves-Berg (1543), and King Francis I of France (1544). However, on the other hand, the Duke confiscated the properties of the Catholic Church in his lands. From the wealth of dissolved monasteries in his country Maurice founded the princes' schools (Fürstenschulen) of Schulpforta (100 places), Meissen (60 places) and Grimma (70 places). The legal basis for this was the "New National Order" (Neue Landesordnung) of 1543. Later, Maurice refused to join the Protestant Schmalkaldic League, although the Landgrave Philip of Hesse, his friend and father-in-law, was its leader. The principal reason for his refusal to do so is generally regarded as his hate for his Ernestine cousin John Frederick I and the Imperial promise of the Saxon electorship, then held by John Frederick. In the Holy Week of 1542, in the process of the Wurzener Feud (Wurzener Fehde) it nearly came to a fratricidal war, because John Frederick occupied the jointly administered "Wurzener Country". There had previously been a controversy between Maurice and John Frederick over the use of tax funds from this area. The intervention of the Landgrave Philip of Hesse and Martin Luther prevented the war. Due to the energetic persistence of the Elector John Frederick in establishing the Protestant Faith, the Emperor Charles V, on 20 July 1546, imposed the Imperial Ban (Reichsacht) on him, with the agreement of the Catholic Imperial Estates, the enforcement of which was laid on Maurice after the Wurzener Feud. The emperor tried in this way to drive a still deeper wedge into the Protestant camp in order to prevent a further propagation of the Protestant Faith. In the case of a successful enforcement, Maurice hoped to be invested by the emperor with the Electorship. Maurice hesitated for a long time, since by this punitive action his father-in-law Philip of Hesse would have been affected also. But when the brother of the emperor, Ferdinand I, himself wanted to initiate a campaign against the
