Gopal Bansa
Gopal Bansa was a dynasty in ancient Nepal, arguably the first, accredited with the discovery of the Pashupatinath volcanic mound in ancient Nepal which is currently the location of the Pashupatinath temple. They habitated the Kathmandu valley before the buffalo herding tribe predominated as well as before first Kirati King Yalamber took control. (This gives a time scale of between 1400 BC and between 700 BC). Dates are based according to a rough estimate of a time after the Kurukshetra war to a time of the 7th documented Kirat King Humati.(see Kalamber) According to legend, the Gopals were brought and setteled by Lord Krishna during dwapara yuga. This dynasty was characterized by small scale subsistence farming and cow husbandry.
