[2] The Bayandur was one of the 7 original tribes that made up the Kimek confederation, along with the Imur[3]/Imi,[4] Imak[3][4] Tatar, Kipchak, Lanikaz and Ajlad.

[5] The Kimek tribes originated in the Central Asian steppes, and had migrated to the territory of present-day Kazakhstan.

The Ak-koyunlu Sultans claimed descent from Bayindir Khan and it is likely, on the face of it, that the Book of Dede Korkut was composed under their patronage.

In default of any better explanation, I therefore incline to the belief that the book was composed before Ak-koyunlu rulers had decided who their ancestors where.

For this reason, the Bayandur tamga is found in Aq Qoyunlu coins, their official documents, inscriptions and flags.
