Pre-independence period In the late medieval period, the elder prince of Dimasa Kachari, Drikpati, and a younger prince, Dakhin, had a conflict. Dakhin and his followers were driven out and built a new capital at the
Barak Valley, declaring themselves as Dibrasa or the Children of the Barak River (
Di means "River", and
Brasa means "Barak"
). The Dibrasa were later known as
Twiprasa and formed the
Twipra Kingdom in the
Barak Valley. In 1562, the
Koch dynasty King
Chilarai invaded and captured the Barak Valley from the Twipra Kingdom. King Chilarai gave his brother, Kamal Narayan, authority over the region. The descendants of Kamal Narayan ruled the region until the 18th century as Khaspur kingdom. Bhima Singha was the last Koch ruler of Khaspur. He had no sons, only a daughter named Kanchani. Kanchani married Laxmichandra, a prince from the Dimasa kingdom of Maibang. After the last Koch king Bhima Singha died, the Dimasas moved to Khaspur. This led to the merging of the two kingdoms, forming the Kachari kingdom under King Gopichandranarayan, and ruled most of the
undivided Cachar district. Raja Shri Krishna Chandra Dwaja Narayan Hasnu Kacharihe was the most powerful king of the Dimasa Kingdom at Khaspur. During Krishna Chandra's rule, the Manipuri king sought help against the
Burmese army. Krishna Chandra defeated the Burmese in battle and was offered the Manipuri Princess Induprabha in thanks. Because Krishna Chandra was already married to Rani Chandraprabha, he asked Princess Induprabha to marry his younger brother, Govinda Chandra Hasnu. During this period, Khaspur was the capital of Cachar. The last king of Cachar was Raja Govindra Chandra Dwaja Narayana Hasnu.
British period The British moved into Assam in 1824 during the
First Anglo-Burmese War, which was then under Burmese occupation. Because he died without a natural heir, his territories were annexed by the British under
doctrine of lapse, adding it as the Cachar district of Assam. == Geography ==
