Various regional Tartar dynasties (916-1234 AD)

Smaller Tartar and Mongol tribes, like Xixia and Liao and others, repeatedly carved Kingdoms and Empires for themselves in northern and north-western China. From the 10th to the 13th century, when they were absorbed by the Mongol Yuan dynasty, they controlled a large portion of China. Some of these tribes issued many different coins, extremely popular with the collectors.
