In the sixteenth century Yashobramha Shah gained the ruling title over the principality of Kaski.

The rulers of neighboring Kingdom of Gorkha were Magar people. They had a tradition of choosing a ruler every fall by way of a running match open to everyone. Whoever won the race was to become the ruler for a year.

However, when Dravya Shah tricked his way to the win and eventually gotten away with the tradition of choosing a ruler every fall. He ruled with an iron fist and executed anyone who suggested the reinstatement of the very tradition of choosing a ruler by which he himself became a ruler^{[citation needed]}.

Dravya Shah himself was not a physically robust man. He, however, had the backing of the Bhattarai, Aryal, Adhikari and Acharya clans of Bahun to propel him to the throne by defeating Magar aspirants to the throne by trickery and cheating instead of pure physical perfection as was the norm. Once he became the king, however, he discontinued the race that was essential among the Magar to anoint the ruler for the next year. By the time of his death in 1570, Dravya Shah had managed to erase the memory of the tradition of choosing the ruler by way of running a match open to everyone. He was a shrewd politician, and with the backing of the above mentioned clan of Bahun, he additionally sought the help of the Pant clan of Bahun. He was a totalitarian king who ruled with an iron fist to silence any dissent. He used the power and might of the magar army to increase the size of the kingdom to include some of the neighbouring states. His successors continued to increase the kingdom's territory.
