The name Mongols (Mongolian: Монгол Mongol) explains one or more ethnic groups. A hard definition includes the Mongols proper (self-designation Monggol), which can be split into eastern and western Mongols. In a bigger sense, the Mongol peoples also people who speak a Mongolic language but use other self-designations, such as the Kalmyks of eastern Europe.
The name Monggol has its meaning in the Tungusic languages and usually means "the invincible ones". At first it was applied to a small and still insignificant tribe in the area of the Onon river. In the 13th century it grew into an umbrella term for a large group of tribes united under the rule of Genghis Khan.
