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.
Suleiman of Persia
Diplomatic activity had already started decreasing since the reign of Shah Abbas I (r. 1587–1629), but it decreased even more under Suleiman. Although Suleiman had requested King William III of England for adept artisans in 1668/69, he is not known to have been involved in an operating foreign diplomacy.
