Transformation of the Ottoman Empire
Sultan Suleiman I (r. 1520–1566) was the longest-reigning sultan in Ottoman history, but the last years of his reign were characterized by uncertainty over who would be his successor. Suleiman had three sons who could hope to succeed, Mustafa, Bayezid, and Selim. While the latter two were the children of Suleiman's wife Hurrem Sultan, the first was the son of an earlier concubine. Mustafa may have felt that his half-brothers possessed an unfair advantage over him, and thus worked to secure the favor of the military. Perhaps suspecting that Mustafa planned to dethrone him just as his own father had done to his grandfather, Suleiman acted first and in 1553 ordered that Mustafa be executed. The death of Hurrem Sultan in 1558 triggered open conflict between the two remaining candidates, and Selim ultimately emerged victorious. Suleiman further strengthened his son's position by arranging a marriage between Selim's daughter and the influential Sokollu Mehmed Pasha (Grand Vizier 1565–1579). Suleiman died in 1566, while besieging the fortress of Szigetvar in Hungary, bringing Selim to the throne.
Sultans Trail
Sultans Trail ("recte" Sultan's) takes its name from sultan Süleyman Kanuni, Suleiman the Magnificent, of the Ottoman Empire who led Ottoman armies to conquer Belgrade and most of Hungary before his invasion was checked at the Siege of Vienna. The main path follows the route of sultan Suleiman the Magnificent on his way to Vienna. He started on 10 May 1529 from Istanbul and arrived 23 September 1529 in Vienna (141 days). It was to be the Ottoman Empire's most ambitious expedition to the west, but the Austrian garrison inflicted upon Suleiman his first defeat. A second attempt to conquer Vienna failed in 1532. In 1566, at the age of 60, the sultan led his army for the last time; he died close to Szigetvár in Hungary.
