be one of crisis and adaptation rather than simple decline, the end of Suleiman's reign was a watershed in Ottoman history. In the decades after Suleiman, the empire began to experience significant political, institutional, and economic changes, a phenomenon often referred to as the Transformation of the Ottoman Empire. Alternative names and titles Suleiman the Magnificent ( Muḥteşem Süleymān), as he was known in the West, was also called Suleiman the First ( Sulṭān Süleymān-ı Evvel), and Suleiman the Lawgiver ( Ḳānūnī Sulṭān Süleymān) for his reform of the Ottoman legal system. It is unclear when exactly the term Kanunî (the Lawgiver) first came to be used as an epithet for Suleiman. It is entirely absent from sixteenth and seventeenth-century Ottoman sources and may date from the early 18th century. There is a tradition of western origin, according to which Suleiman the Magnificent was "Suleiman II", but that tradition has been based on an erroneous assumption that Süleyman Çelebi was to be recognised as a legitimate sultan. Early life Suleiman was born in Trabzon on the southern coast of the Black Sea to Şehzade Selim (later Selim I), probably on 6 November 1494, although this date is not known with absolute certainty or evidence. His mother was Hafsa Sultan, a convert to Islam of unknown origins, who died in 1534. At the age of seven, Suleiman began studies of science, history, literature, theology and military tactics in the schools of the imperial Topkapı Palace in Constantinople. As a young man, he befriended Pargalı Ibrahim, a Greek slave who later became one of his most trusted advisers (but who was later executed on Suleiman's orders). At age seventeen, he was appointed as the governor of first Kaffa (Theodosia), then Manisa, with a brief tenure at Edirne. Accession Upon the death of his father, Selim I (r. 1512–1520), Suleiman entered Constantinople and ascended to the throne as the tenth Ottoman Sultan. An early description of Suleiman, a few weeks following his accession, was provided by the Venetian envoy Bartolomeo Contarini: Military campaigns Conquests in Europe Upon succeeding his father, Suleiman began a series of military conquests, eventually leading to a revolt led by the Ottoman-appointed governor of Damascus in 1521. Suleiman soon made preparations for the conquest of Belgrade from the Kingdom of Hungary—something his great-grandfather Mehmed II had failed to achieve because of John Hunyadi's strong defense in the region.
