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.
Selim I
Selim was one of the Empire's most successful and respected rulers, being energetic and hardworking. During his short eight years of ruling, he accomplished momentous success. Despite the length of his reign, many historians agree that Selim prepared the Ottoman Empire to reach its zenith under the reign of his son and successor, Suleiman the Magnificent.
