In light of recent developments, there has been speculation that Moscow might increase its support for the Kurds in Syria and Iraq and might even lend support to the Kurds in Turkey. To what extent is such a scenario possible and what might the implications be? Any understanding of the Kurds is incomplete without an understanding of their diversity. Although united by common aspirations for basic civil rights and self-determination, the Kurds do not form a single monolithic bloc. Twenty-eight-million strong, they straddle the mountainous frontier territories of Turkey, Iraq, Syria and Iran. They comprise various tribes and speak an array of different dialects and languages, including Kurmanji, Sorani, Pehlewani, Zazaki, and Gorani, although Kurmanji is the most widely spoken. There are also Muslim Kurds (both Sunni and Shia) as well as Yazidi Kurds.
