Yassi Chimen War - The first Ertugrul's Glory !
Moving west, the Kaya tribe temporarily stopped near Sivas, where Ertugrul encountered a battle between the Seljuk state led by Sultan Alaeddin Kaykubat and the Mongol state of Haresmshah.
The Mongols advanced in the war and the Seljuk army was on the verge of defeat, then Ertugrul and his warriors joined the war on the side of the Seljuk army, which changed the situation and the Seljuk army repulsed the Mongol attacks and won the battle.
It was the Yassi Chimen War, in which the Seljuk state allied with the Ayyubid State fought the Mongols in 1230.
In gratitude for taking part in this battle, Sultan Alaeddin Kaykubat gave permission to the Kaya tribe to settle in the territories around Sogut and Domanich, on the borders with the Byzantine Kingdom, and from there to take part in the battles of the Seljuk army.
Ertugrul Gazi became a well-known and respected figure, both in the Seljuk State and among the Turkmen tribes, as well as throughout the Islamic world.
