Rajasimla, situated in the north-east corner of
East Garo Hills District, is a significant place for Garo Christians. It is one of the earliest villages to be visited by the American Missionaries.
It is the place where the American Baptist Missionaries laid the foundation of a church on 14th April, 1867. Accordingly, they gained two converts named Omed and Ramke, who opened a school and worked actively to propagate the Christian message.
The place is named after the treaty signed between the Zamindar (the head of the village) of Bijni and the villagers. This treaty marked the particular spot as the boundary between the territory of the Zamindar and Garo villages.
Presently, Rajasimla acts as a base for socio-cultural contacts among the surrounding villages. The people here are talented and art forms such as Kalsin-Sonatchi and Serejing Wal'jan are regularly staged.
