The Oguz tribes were a group of Turkish people who traveled through Asia with their king on horses, as horses were the main mode of transportation at the time. They originally lived in northern China but moved west, ending up near the Caspian Sea in Dagestan, possibly due to a conflict with other Oguz tribes over land, gold, jewelry, or food. The Oguz tribes were the ancestors of modern Azerbaijanis and influenced Azerbaijani culture, with foods like kabab originating from the tribes.
