The Serican established the kingdom in 1250. It became powerful in 1508 conquering much of Asia.
Little Turks or Turculi, Chungans, a member of a Turkic people mixed with Asiatic and nomadic blood. They became a separate people in the early days of conquest and also adopted their own distinct language and culture.

Chungan were absorbed into the Turkic and Mongol population in the 16th and 17th century. They traded with these tribes and this made to their culture and their language became unified in 1855.
