Budhhi Karna Rai

Buddhi Karna Raya Khebang ("Nepali : बुद्धिकर्ण राय") was the last king(Rai) of Morang Bijypur till his assassination by Gorkhali king Prithvi Narayan Shahs forces in 1774 AD. His Limbuwan kingdom was lands between Saptakoshi River to Kankai River covering present day three districts: Sunsari, Morang and parts of Jhapa.
Rise of Budhhi Karna.
After the assassination of Kama Datta Sen, Buddhi Karna came to Bijaypur and became the last Limbu king of Morang and Dewan of Limbuwan. But on hearing of the death of King Kama Datta Sen, all the states that made up Limbuwan and their allies split up. The kings of Limbuwan no longer had allegiance to Buddhi Karna. He seriously needed able ministers and chiefs to assist him in ruling Morang and all of Limbuwan. He sent people to look for King (Hang) Shamo Hang Chemjong of Miklung Bodhey Kingdom to help him.
Death of Budhhi Karna.
He was tricked into coming to Bijaypur- Dharan (Limbuwan) for a negotiation, then killed by the assassins of Gurkha King Prithvi Narayan Shah in 1773 A.D, Budhhi Karna Khebang's soul is believed to have wandered around the area of his tomb (Budha Subba Temple) around Bijaypur and was said to be a friendly and helpful spirit. Then local Limbu people started worshiping the soul as an old Limbu king (Hang) believing it to bring good luck. In Limbu language Hang means King.
