Which sultan of the Ottoman Empire was called 'the Magnificent'?

Suleiman I (6 November 1494 – 6 September 1566), commonly known as Suleiman the Magnificent in the West and Suleiman the Lawgiver in his realm, was the tenth and longest-reigning Sultan of the Ottoman Empire from 1520 until his death in 1566. Under his administration, the Ottoman caliphate ruled over at least 25 million people.

Suleiman succeeded his father, Selim I, as sultan in September 1520 and began his reign with campaigns against the Christian powers in central Europe and the Mediterranean. Belgrade fell to him in 1521 and the island of Rhodes in 1522–23. At Mohács, in August 1526, Suleiman broke the military strength of Hungary.

Breaking with Ottoman tradition, Suleiman married Hürrem Sultan, a woman from his harem, an Orthodox Christian of Ruthenian origin who converted to Islam, and who became famous in the West by the name Roxelana, due to her red hair. Their son, Selim II, succeeded Suleiman following his death in 1566 after 46 years of rule.
