[2] By the beginning of the 1st millennium CE, the Ningthouja Dynasty began to emerge in Imphal River valley, overrunning the territory of the Khaba clan.

[3] From Kangla they absorbed the surrounding clan principalities of Luwang, Moirang, Khaba-Nganba, Angom, Sarang-Leishangthem and Khuman.

Since 33 CE till the rule of the last King Bodhchandra, Manipur was ruled by seventy-four kings, of whom the hallowed reign of Pakhangba, Naothingkhong, Loiyumba, Kiyamba, Khagemba, Charairongba, Pamheiba, Maharaja Jai Singh, Maharaja Gambhir Singh, Maharaja Nara Singh, Chandrakirti and Churchand are outstanding.

On the inherent title and privilege of the princes Major Maxwell, the then British Political Agent in Manipur and the regent of the young Raja Churchand Singh writes:"Rajkumars, or as they are called in Manipur Ninthou Machas, a Rajas, are very numerous; if, for instance, a Raja had eight sons and these sons were equally well blessed with male issue, the whole 64 grandsons would be Ningthou Machas, and their sons again, and so on."

Rajkumars were a troublesome people, Major Maxwell observed and he gave them little encouragement.
