Establishment of the Second Bulgarian Kingdom and Cuman/Kıpchaks in Bulgarian historiography

The Cumans, which have an effective and dynamic aspect within the Turkish tribes, left important traces in a wide geography when the fields of their action and span in history were examined. In a short period of time, they reached the Balkans through the Russian steppes and succeeded in taking important roles in this region's politics. In the last quarter of the 12th century, in the North of Bulgarian geography dominated by Byzantium, there was a rebellion largely based on economical reasons and this upraising were led by two brothers, Asen and Peter, who were Cuman descent. As a result of this rebellion, Cumans, Bulgarians and Vlachs gained their freedoms and the Second Bulgarian State declared its independence. Many studies have shown that without Cumans, this rebellion couldn't succeed. In the XIII- XIVth centuries, the Terter and Sishman Dynasties which governed in the same state, were also descents of Cuman. In the sources of the period, the military and political importance of Cumans is clearly seen. It is also a historical fact that Cumans have a role in the formation of this geography. The approaches of Bulgarian historians on the subject vary according to the political conjuncture.
