According to traditions, Keonjhar State was founded during the 12th century rule of the
Eastern Ganga dynasty when the founder Jyoti Bhanja of the
Bhanja dynasty, who was the brother of Adi Bhanja of Mayurbhanj, was enthroned as the Raja of Keonjhar with the help of the dominant local
Bhuyan clans. The influence of the Bhuyans on the enthronement rituals and regnal traditions of Keonjhar suggests a long-standing relationship with the kingdom. Around the 14th century, a prince from Keonjhar named Ananga Bhanja, who was a nephew of the Raja of Keonjhar was named the king of Baudh by the local chieftains under Ganga rule. After the
independence of India in 1947 Keonjhar merged into
Republic of India on 1 January 1948 following which it became the part of
Keonjhar district (now Kendujhar). ==Rulers==
