The Gurkhas History

The majority of the early Gurkhas were from the Thakuri/Rajput (which includes the Shah dynasty and Rana dynasty of Nepal), Chetri and Brahmin ethnic groups, whereas the modern Gurkha soldiers are mainly from the Limbu, Rai, Gurung and Magar ethnic groups. They joined the Gurkhas during 17th century expansion of the Gurkha kingdom.[4] However, even today the Thakuris and Chetris make up the majority of Gurkha officers in Nepal, while the backbone of the Gurkha army is mainly Limbu, Rai, Gurung and Magar people, this combination of warriors from different ethnic groups made the Gurkhas a dominant military force in the history of the Indian subcontinent since the 18th century.
