Final answer:
Suleiman's treatment of non-Muslims can be described as respectful.
Step-by-step explanation:
The word that best describes Suleiman’s treatment of non-Muslims is respectful.
Suleiman the Magnificent, who ruled the Ottoman Empire from 1520 to 1566, implemented a policy of religious tolerance towards non-Muslims. He allowed his non-Muslim and European subjects to remain in Istanbul and treated them with respect. This can be seen in his invitation to scholars and artists from Asia and Europe to Istanbul, as well as his reforms that ensured fair treatment and legal rights for all Ottoman subjects.
