The term "Bey" is commonly associated with various regions, particularly in the Ottoman Empire, where it was used as a title for leaders or governors of provinces. Beys were often in charge of territories and held significant authority.
One notable example of a country where rule by Beys was significant is Tunisia, which was governed by a series of Beys before becoming a French protectorate in the late 19th century. The term can also apply to other regions in North Africa or the Middle East influenced by Ottoman governance.
