Hinduism is the main and largest dharma of Nepal. In 2006, the country declared itself a secular country through democracy, after the abolition of its monarchy. According to the 2021 census, the Hindu population in Nepal is estimated to be around 23,677,744 which accounts for at least 81.19% of the country's population, the highest percentage of Hindus of any country in the world. Vikram Samvat, one of the two official calendars used in Nepal, is a solar Hindu calendar essentially the same to that widespread in North India as a dharmic calendar, and is based on Hindu units of time.

Chhetri, historically called Kshettriya or Kshetriya or Khas are Nepali speaking Rajputs of Khas community, some of whom trace their origin to migration from medieval India. Chhetri was a caste of administrators, governor and military elites in the medieval Khas Kingdom and Gorkha Kingdom. The nobility of the Gorkha Kingdom mainly originated from Chhetri families. They also had a strong presence in civil administration affairs. The bulk of prime ministers of Nepal before the democratization of Nepal belonged to this caste as a result of the old Gorkhali aristocracy. Gorkha-based aristocratic Chhetri families included the Pande dynasty, the Basnyat dynasty, the Kunwar family, and the Thapa dynasty,.
