When India got it's Independence in 1947, all the Nawabs, kings, and Princes were stripped of their royal titles. Henceforth, in democracitc India, If they wanted to come to power, like any common people, they had to stand for election and win it. They were big, powerful kings. The Nizam of Hyderabad was considered the richest man in the world. Many of them controlled areas larger than Nepal's. I think we should also follow the same path that India took back in 1947.
