Suleiman I, commonly known as Suleiman the Magnificent in Western Europe and Suleiman the Lawgiver in his Ottoman realm, was the longest-reigning sultan of the Ottoman Empire from 1520 until his death in 1566. Under his administration, the Ottoman Empire ruled over at least 25 million people.

The Ottoman Empire, historically and colloquially known as the Turkish Empire, was an imperial realm that spanned much of Southeast Europe, West Asia, and North Africa from the 14th to early 20th centuries; it also controlled parts of southeastern Central Europe between the early 16th and early 18th centuries.
