Who was called "Suleiman the Magnificent"?

Suleiman I (6 November 1494 – 6 September 1566), commonly known as Suleiman the Magnificent in the West and Kanunî Sultan Süleyman ("The Lawgiver Suleiman") in his realm, was the tenth and longest-reigning Sultan of the Ottoman Empire from 1520 until his death in 1566.

Suleiman became a prominent monarch of 16th-century Europe, presiding over the apex of the Ottoman Empire's economic, military and political power. He personally led Ottoman armies in conquering the Christian strongholds of Belgrade and Rhodes as well as most of Hungary before his conquests were checked at the Siege of Vienna in 1529. Under his rule, the Ottoman fleet dominated the seas from the Mediterranean to the Red Sea and through the Persian Gulf.

He personally instituted major legislative changes relating to society, education, taxation and criminal law. His reforms, carried out in conjunction with the empire's chief judicial official Ebussuud Efendi, harmonized the relationship between the two forms of Ottoman law; sultanic (Kanun) and religious (Sharia). He was a distinguished poet and goldsmith; he also became a great patron of culture, overseeing the "Golden" age of the Ottoman Empire in its artistic, literary and architectural development.

He married Hürrem Sultan, a woman from his harem, a Christian of Ruthenian origin who converted to Islam, and who became famous in the West by the name Roxelana. Their son Selim II succeeded Suleiman following his death in 1566 after 46 years of rule.
