The Nankar system predominantly involved individuals from the lower castes of Hindu society, such as Kiraans, Namasudras, Malis (gardeners), Dhulis, Napits (barbers), and Patnis.

From 1922 to 1949, with the help of the Communist Party and Peasants Association, a Nankar movement against the feudalistic exploitation system was developed and centered in Bahadurpur, Lauta in Beanibazar, and spread to other Nankar-populated areas such as Golapganj, Barlekha, Kulaura, Balaganj and Dharamapasha.

[1] On the 17th of August 1949, there was an important festival day, Makar Sankranti, in reference to deity Surya (sun), for Bengali Hindus.

During the first day of this religious festival, the Nankar Hindus in Saneshwar Uluri began preparing to worship Manasa late at night until they start to feel sleepy.
