What are the Governorates of Tunisia?

Tunisia is divided into 24 governorates (wilayat), each headed by a governor appointed by the president and divided into delegations and municipalities. The governorates were created in 1956, the year Tunisia won independence from France, replacing the colonial-era system of caidats. There were originally 14, and several were later split off as the population grew. Many were carved out of the area around the capital: Ben Arous and Ariana were created from Tunis, and Manouba from Ariana in 2000. Most governorates are named after their capital city, such as Sfax, Sousse, Bizerte and Kairouan.
