Tunceli Province (, , ), formerly Dersim Province, is located in the Eastern Anatolia region of Turkey. It has a majority Alevi Zaza  Kurdish population with a minority Sunni Turkish population. The province was originally named Dersim Province (Dersim vilayeti), then demoted to a district (Dersim kazasi) and incorporated into Elâzig Province in 1926. It was finally changed to Tunceli Province on January 4, 1936 by the "Law on Administration of the Tunceli Province" (Tunceli Vilayetinin Idaresi Hakkinda Kanun), no. 2884 of 25 December 1935, but some still call the region by its original name. The name of the provincial capital, Kalan, was then officially changed to Tunceli to match the province's name.
