The Baise Rajya (Nepali: बाइसे राज्यहरू, lit. ‘22 kingdoms’) were sovereign and intermittently allied petty kingdoms in the western hills of what is now Nepal, located around the Karnali–Bheri river basin. They formed after the break up of the Khasa-Malla kingdom.These kingdoms were ruled by local dynasties, of Magar chieftains, depending on the region. Several of these kingdoms, particularly in areas like Rukum, Rolpa, and Pyuthan, had strong Magar leadership and populations. The Baise states maintained varying degrees of independence until they were gradually annexed during the unification of Nepal from 1744 to 1810. Although Prithvi Narayan Shah (r. 1743–1775), the founder of the Gorkha kingdom, initiated the unification, it was completed under his successors by the end of the 18th century.
The 22 principalities were Jumla, Doti, Jajarkot, Bajura, Gajur, Malneta, Thalahara, Dailekh District, Dullu, Duryal, Dang, Sallyana, Chilli, Tulsipur State, Darnar, Atbis Gotam, Majal, Gurnakot, and Rukum. These Baise states were ruled by Khasas and several decentralized tribal polities.
