mixture of mostly West Eurasian lineages maternal lineages and minority of East Eurasian lineages. Turkmens also have two unusual mtDNA markers with polymorphic characteristics, only found in Turkmens and southern Siberians. History Turkmens belong to the Oghuz tribes, who originated on the periphery of Central Asia and founded gigantic empires beginning from the 3rd millennium BC. Subsequently, Turkmen tribes founded lasting dynasties in Central Asia, Middle East, Persia and Anatolia that had a profound influence on the course of history of those regions. The most prominent of those dynasties were the Ghaznavids, Seljuks, Ottomans, Safavids, Afsharids and Qajars. Representatives of the Turkmen tribes of Ive and Bayandur were also the founders of the short-lived, but formidable states of Kara Koyunlu and Ak Koyunlu Turkmens respectively. Turkmens that stayed in Central Asia largely survived unaffected by the Mongol period due to their semi-nomadic lifestyle and became traders along the Caspian, which led to contacts with Eastern Europe. Following the decline of the Mongols, Tamerlane conquered the area and his Timurid Empire would rule, until it too fractured, as the Safavids, Khanate of Bukhara, and Khanate of Khiva all contested the area. The expanding Russian Empire took notice of Turkmenistan's extensive cotton industry, during the reign of Peter the Great, and invaded the area. Following the decisive Battle of Geok Tepe in January 1881, the bulk of Turkmen tribes found themselves under the rule of the Russian Emperor, which was formalized in the Akhal Treaty between Russia and Persia. After the Russian Revolution, Soviet control was established by 1921, and in 1924 Turkmenistan became the Turkmen Soviet Socialist Republic. Turkmenistan gained independence in 1991.
