Köten or Kotyan (variously Kutan, Kuthen, Kuthens, Kotyan, Kotjan, Koteny, Kötöny, Kuethan, Zayhan, or Jonas) (fl. 1223–39) was a Cuman military commander and khan (lord) of the Terteroba clan during the mid–13th century.
He forged the Cuman–Kievan Rus alliance against the Tatars. His son-in-law Mstislav the Bold, the Prince of Halych. Köten was allegedly of the Terteroba clan. He participated in the power struggles between the princes of Kyivan Rus' in 1202, 1225 and 1228. After the defeat by the Mongols in 1222, he convinced the princes of Kyivan Rus' to forge an alliance against the Mongols. He fought in the war against the Mongols (allied with the Russians) in the Battle of Kalka River, where the Rus-Cuman alliance was defeated.
The Cuman–Kipchak confederation under Köten and a Rus army of 80,000 men under his son-in-law Mstislav the Bold fought a battle at the Kalka River (Kalchik, near Mariupol) against a Mongol contingent commanded by Jebe and Sübötäi. The Rus-Cuman army was routed and had to retreat (31 May 1223). Köten was deposed from power in that year, but he remained leader of the Terter tribe.
Here I stand a broken man
Broken dreams slipped trough my hands
What once was is now gone
I can't go on, I am done
Last call
Last change to make things right
Pick up the pieces and mend my life
But how can I heal a broken trust
It feels so hard, it rips my guts
