context: The name "China" according to the common version comes from the name "Katay", which, in turn, arose from the name of not the Chinese, but the proto-Mongolian group of nomadic tribes from Manchuria - Khitan (Chinas). In 907, they captured North China and founded their Liao dynasty in it. Their place in the XII-XIII centuries was taken by other nomads - the Jurchen and the Mongols, but the ethnonym of their predecessors was fixed as the toponym of Northern China. Thanks to European merchants, in particular, Marco Polo, this name in the form of Cathay fell into medieval Western Europe. From here it passed into most Slavic languages, where it turned into "China." In the West, Katai is occasionally used as the poetic name of China.
