Suleiman the Magnificent led one final campaign in 1566, ending at the siege of Szigetvár. The Siege was meant to be only a temporary stop before taking on Vienna. However, the fortress withstood against the Sultan's armies. Eventually the Sultan, already an old man at 72 years (ironically campaigning to restore his health), died. The Royal Physician was strangled to prevent news from reaching the troops and the unaware Ottomans took the fort, ending the campaign shortly afterward without making a move against Vienna.
