Suleiman the Magnificent
Suleiman I ( '; or '; 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. Under his administration, the Ottoman state ruled over 15 to 25 million people.
Ottoman dynasty
The first Ottoman ruler to actually claim the title of "Sultan" was Murad I, who ruled from 1362 to 1389. The holder of the title Sultan (سلطان in Arabic) was in Arabic-Islamic dynasties originally the power behind the throne of the Caliph in Bagdad and it was later used for various independent Muslim Monarchs. This title was senior to and more prestigious than that of Amir; it was not comparable to the title of Malik 'King', a secular title not yet common among Muslim rulers, or the Persian title of Shah, which was used mostly among Persian or Iranian related rulers.
