The Onoq Western Turkic Khaganate is a Turkic khaganate formed as a result of the internecine wars in the beginning of the 7th century (593 – 603) after the Göktürk Khaganate (founded in the 6th century in Northern Mongolia by the Ashina clan) had splintered into two polities – Eastern and Western.The Western Turks initially seek friendly relations with the Eastern Roman Empire in order to expand their territory at the expense of their mutual enemy, the Sassanid Persian Empire.

The Western Turks are also known as the Onogurs or Onoghurs, from the proto-Turkic Onoq ("ten arrows").

An "arrow" is a name for one division of the Turkic tribes.

The division now known as the Utigurs or Bulgars eventually migrates southwest and forms the First Bulgarian Empire in Moesia.
