After coming under British influence, in 1809 they transitioned from feudal monarchs into rulers of a princely state, though the Manikyas maintain control of the region until 1949, when it ascended in union with India.

Tracing a descent from the mythological Lunar dynasty,[1] the Rajmala royal chronicle records an unbroken line of 144 (likely legendary) monarchs of Tripura up to the ascension of one Ratna Fa, who is stated to have become the first Manikya after being granted the cognomen by the Sultan of Bengal.

As monarchs of a Hindu kingdom, the Manikyas developed a rivalry with the successive Muslim rulers of Bengal, coming into conflict with Sultans, governors and Nawabs before being brought under Mughal suzerainty in the early 17th century.

After Tripura was briefly incorporated into the province of Eastern Bengal and Assam at the beginning of the 20th century, the last Manikya monarch, Maharaja Bir Bikram Kishore, chose to come under the jurisdiction of the predominantly Hindu Dominion of India in 1947.

The final ascension of Tripura into the modern Indian nation was signed by his widow, Kanchan Prava Devi, in place of the minor Kirit Bikram Kishore, bringing to an end five centuries of Manikya rule.
