About the history of the Molsoms, or Halams very little is known. According to the experts, the Molsoms belong to the Indo-Mongolian racial family. Culturally they are closely linked to Tripuri people on general, but due to conversion to foreign religion some sub tribes may have changed their culture to western onslought of conversion. Linguistically, they are closely related to the Kuki sub-family as well as Bodo group of of the Tibeto-Burman family, due to inter mixing of Boro group and Kuki group of Tibeto Burman Languages. It is presumed that they have migrated from somewhere near the Burma-frontier in the east. But none can produce accurate evidence with reference to the above statement till today.

Origin:
It is very difficult to trace the origin of the Molsoms. Because, there is no recorded evidence to show where the Molsoms came from, how they came and when they settled in Tripura. All we know is that they are now son of soil. They are found settled in Udaipur, Amarpur, Sonamura, Sadar, Khowai, Gandachara and Kamalpur Sub-Divisions of the state. Recently, they are also being settled in Kanchanpur Sub-Division of North Tripura District. But they are not found in Sabroom and Belonia Sub-Divisions of South Tripura District.

Undoubtedly, it is a sub-group of Halam community. According to common belief that the Molsoms are known as No. 1 Halam in the long past and is prevailing till today. It is therefore, taken for granted that the culture of the Molsoms must be similar to that of the rest of Halam sub-tribes. On the other hand, it is also reveals that little variation in regard to their traditional food habits, rites and rituals, dialectical pronunciation are worth mentioning today.

 Sub Community:
As we know that the Halam Community consists of some sub-tribes, namely, (1) Molsom, (2) Kaipeng, (3) Hrangkhawl, (4) Kalai, (5) Rupini, (6) Bongcher, (7) Karbong, (8) Langkai, (9) Chorai, (10) Morsophang, (11) Ranglong and (12) Thangachep.

The Koloi  and Rupini subgroups do not fall under the Halam Group pf Tripuri people, infact they are small independent group of Tripuri people. They had been classified in this group during the 1901 census was because their numbers were very small to be classified as an independent group, so the data compilers of census of that year included in the minority group of Halam. Since then these Koloi and Rupini have been illogically classified as Halams by many sociologist and historians. But on the contrary there is nothing both ethnically, linguistically or culturally to classified them as Halams. It is strongly urged that the Koloi and Rupini be classified as separate group llike Jamatia, Riang etc.

 In addition to the above the following sub-tribes also subsequently included into the Halam. They are (1) Natianglong., (2) Nasbang, (3) Saimar, (4) Dab and (5) Sangachep. Actually, these sub-tribes like Bongcher, Karbong, Langkai, Morsophang, Ranglong and Thangachep sub tribes.

  But the folk tale tells that the Molsoms had been originally residing in the village named Arsien Khosak that was situated at Bolpuitang. In this connection, it may be mentioned here that the Molsoms believe that all human being were once under earth. The area of Arisienkhosak was so large that if any one traveled all over the village with a wet wrapper made row cotton that is locally called Ponpui then the wrapper would dry up by the time the walk was completed. In that village all Molsom were under control of the community chief Kamchikao. Along with other activities, the Kamchikao had collect subscriptions for the annual Sengrak worship. Besides, he had to arrange for daily worship of Sengrak.

 Once the Kamchikao was so busy in collecting subscription that for several days he had forgotten to arrange for hens for the daily Sengrak worship. The Sengrak became angry since no hen was offered to Him on all those days and in anger he left the village and went to nearby hill. By that time, an evil spirit named Rurengnu entered the village and started killing one person of the village everyday. But the villagers were unaware of this in the beginning due to the density of the population in the village, the loss of one person every day was almost ignored by them. But they became trance when one day the daughter of the Knchikao was missing. Kamchikao ordered all the villagers to apprehend the person or thing responsible for the missing of his daughter. Every youth of the village than started searching day and night for the abductor. In the mean time Sengrak came to know, by the exercise of his supernatural power, al about the Rurengnu. He then got converted a snake and entered into the village in the form of a snake, the watch party killed it by cutting its head. The Sengrak however could save himself due to his supernatural power. The watch part then distributed the flesh of that snake among the villagers. An old widow got its head as per her share, which she kept above the hearth to dry up for future consumption.

Next day in the early morning the snake-head cried out like a hen and ten in clear human voice told the widow to flee elsewhere because an earthquake would destroy the village. The widow conveyed the forecast to all villagers without delay.

 All people of the Arsienkhosak, accordingly, vacated the village that morning with their belongings. They had to cross a river on their way to another hillock. It was too deep and the water too cold to across. They made a rope-bridge with fibre of a local tree known as ronrui and stared crossing the river. The Kamchikao was supervising the safe movement of the villagers across the rope-bridge.

 After all the villagers had crossed, the Kamchikao started crossing the bridge and as soon as he stepped on to the bridge, it broke down. He cried out for help. The widow then declared that it was because of the sin committed by the Kaamchikao to Sengrak that he failed to cross the river. She advised him to worship Sengrak by sacrificing a hen from the tail part of which no feather is lost, in fact indicates a matured hen. The widow then told the Kamchikao that only after worshiping the Sengrak he would be able to cross the river. After that the widow and other villagers left the place. They then reached a hill named Relhi champhai where they settled for some period.

 The settlement area of Relhi champhai of the Mizoram also scattered over ten hillocks and as per their staying, it was situated near present Mizoram.
