Kurdistan can be divided historically, and on a socio-economic, cultural, and political basis, into five major subdivisions: southern Kurdistan centered historically on the city of Kirmanshâh, central Kurdistan centered on Arbil, eastern Kurdistan centered on Mahabad, northern Kurdistan centered on Bâyazid, and western Kurdistan centered on Diyârbakir. The two large, detached Kurdish enclaves in Khurdsân and central Anatolia merit separate treatment.
