Pechenegi
The Pechenegs are Turkic nomadic people who lived in the coastal steppes of Central Asia and the Black Sea north of the 12th century. I used the Pesennegu language belonging to the Turkic language family. The Pechenegs originated in the Turks, lived on the Volga and Urals, and settled on the Crimean Peninsula of Eurasia in the south-west from the 9th to the 10th century. By the mid-10th century Byzantine Emperor Constantinople PROFIROGENITUS describes in his writings that their territory is widespread to the west and the Siret River and is about four days away from Hungary. The Pechenegs, pushed by the Hazar in 889, continued to clash with the Mazar, and the Byzantine empire, from the 9th century, hired them as mercenaries to control the more dangerous tribe of the Ruth and Mazar.
