The Ottoman Empire was a large and powerful empire that spanned from the 14th to the 20th century. During this time, the empire was ruled by a series of governors known as Beys and Deys. Beys were appointed by the Sultan and were responsible for the administration of the provinces, while Deys were elected by the local population and were responsible for the day-to-day governance of the cities. Both Beys and Deys had significant power and influence in the Ottoman Empire.
