Itbarak
Itbaraks or just Baraks are Turkic mythological creatures. They were "dog headed, dark coloured manly creatures". According to the Oghuz Khagan Narratives, their country was in the "unknown northwest". It can be assumed that it's around today's Siberia. Oghuz tried to invade them but couldn't succeed, so he had to retreat to a small island.
Dog-headed men
A huge part of Oghuz Khagan Narratives was about "invasions on dog-headed men". Turks called them "Itbaraks". "It" means "dog" and "Barak" means a dark, shaggy dog species. After Oghuz Khagan's invasion on Itbaraks failed, he retreated to a small island, where one of his soldiers' widows gave birth. Oghuz Khagan and his people had no home or tent, so the woman gave birth in a hollow. Oghuz named this child "Kıpçak ", meaning "hollow" in Old Turkic.When Oghuz Khagan had invaded Itbarak lands after 17 years, he gave the lands to Kıpçak to rule. Year after years, Kıpçak's lineage has believed to become the old Turkic tribe Kipchaks.
