The Bhutanese are the Drukpas meaning the inhabitants of Druk Yul. They are generally categorized into three broad ethnic groups. The Sharchops are people of the East and are held to be the indigenous inhabitants of the country. The dialect spoken by most of the people in the eastern region is called Sharchopkha. The people of Western Bhutan are called Ngalongs whose descendents are traced to neighbouring Tibet. They speak Dzongkha, which is the national language. The Lhotshampas are the people of the south who began settling in southern Bhutan in the beginning of the 20th century. They are of Nepalese origin and speak Nepali.
