Suleiman the Magnificent (محتشم سليمان Muḥteşem Süleymān), as he was known in the West, was also called Suleiman the First (سلطان سليمان أول Sulṭān Süleymān-ı Evvel), and Suleiman the Lawgiver (قانونی سلطان سليمان Ḳānūnī Sulṭān Süleymān) for his reform of the Ottoman legal system.

It is unclear when exactly the term Kanunî (the Lawgiver) first came to be used as an epithet for Suleiman. It is entirely absent from sixteenth and seventeenth-century Ottoman sources and may date from the early 18th century.

There is a tradition of western origin, according to which Suleiman the Magnificent was "Suleiman II", but that tradition has been based on an erroneous assumption that Süleyman Çelebi was to be recognised as a legitimate sultan.
