They are the Arakanese descendants who live in the Indian state of Tripura since the Arakan kingdom's control over Tripura in the 16th centuries. Arakanese descendants living in present-day Bangladesh are known as Magh or Marma people.
The Mog Buddhists  have close affinity with Burmese Buddhism in all socio-cultural and religious aspects. Though they live in Tripura, almost all Dhamma books (Tipiíaka, Aííhakathâ, Burmese Myanmar Translationss etc.) are brought from Myanmar and Dharma teaching is done in Burmese Myanmar script. The dialect that the Mog people speak is similar to that of Burmese/Myanmar and Arakanese/Rakhine language with little variation in pronunciation, but the script is the same (Burmese/Myanmar script).
There is a controversy over the origin of the word 'MOG' or 'MOGH'. In a periodical magazine of the Burmese Research Society, this 'word' has been desired to originate from Bengali. But in the model Bengali Dictionary of Bangiya Sahitya Parishad, the origin of this word is 'unknown'. In another Dictionary this word is claimed to have originated from a Burmese word 'Mogh' which is generally used as an epithet before the name of a gentleman. Some others of course referred to the ancient Mogadha Empire for its origination. But it is said that when the domination of Hindu religion began to thrive in this ancient center of Buddha religion, a branch of Mogadha dynasty left for Burma and subsequently settled down in Burma. Later they entered Southern Arakan for 1st Budddist settlement by Burmese king Anawratha Minsaw.
Probably the word mongo came from mogadhi (one who hails from Mogadha, or one who is a resident of Mogadha). In English dictionary the words Mog, Mog, Mog have been shown as surnames to the inhabitants of Arakan in 15-th and 16-th centuries. Bengalis of course refer to the inhabitants of Arakan as 'Mog'. The people of 'Mog' community claimed to have come from Arakan and settled down in Tripura in 957 A.D. Almost all the people belonging to the Mog community are the followers of Buddhism. Sangrai (last day of the month of Chaitra, which is the last month of the Bengali Calendar Year) is the occasion of special festival. The people of the Mog community in general and the young boys and girls in particular celebrate the day through cultural programs to invite the new year. Cakes are prepared at every home and people move from house to house to eat cakes. On this day water is carried through auspicious pitchers and respected persons are allowed to take bath with this water. The young boys and girls indulge in aquatics and traditional ‘Khouyang’ is played on bet. Paste of fragrant sandalwood and water of green coconuts are sprinkled in every house. In the midst of pomp and grandeur fragrant water is poured on the root of 'Bodhi Briksha'. The festival continues for three days.The people of Mog community observe austerity from the full moon of Bengali month of ‘Ashadh’ down to the full moon Bengali month of ‘Ashwin’. Generally no auspicious occasion like marriage is celebrated during the period. Even the married women do not go to their parents' house during this time. 'Wa' festival is celebrated on the day of full moon of the Bengali month of ‘Ashwin’. Lamps dedicated to the Lord Buddha are launched on this day. The young boys and girls stand in rows with lamps in hand to worship the Lord Buddha. The youngsters indulge in merriment through songs and dances in the premises of Buddha temple. The traditional dance of the Mog community is known as 'Wa Dance' or 'Lamp Dance'.
Though it is not clear who was the first Buddhist king who ruled Tripura, it is evident from Archeological findings of Pilak and Boxnagar (Buddhist sites) that the earliest rulers of Tripura were Buddhists dated back to the 2nd and 3rd centuries A.D. According to "Rajmala" the historical record of the royal lineage of Tripura, the Mog (Burmese origin) were the powerful Buddhist kings of Tripura. Buddhism flourished in Tripura from 2nd to 9th century A.D. Both Theravada and Mahayana forms of Buddhism were practiced, though Theravada Buddhism seemed to have had stronghold in many parts of Tripura for many centuries. A few months back, the Government of Tripura has excavated a cetiya (pagoda) resembling the Amravati Stupa which is now safe-guarded by the authority of Archeological Survey of India. This excavated pagoda is understood to belong to 2nd or 3rd century A.D. Many Buddha statues have also been excavated at the site. Pilak is another archeological Buddhist site situated in South Tripura District. Statues of Buddha, Avalokiteòvara and Târâ were found at Pilak site dated back to the 7th and 8th centuries A.D. Archeologists and research scholars opined that Mahayana and Theravada Buddhist traditions might have been dominant in this region extending to Pattikera and Mainamati in Bangladesh.
