Hence it would seem that they were originally one tribe with the Kols, but have been separated for so long a period that their direct connection can no longer be proved.

The disintegrating causes which have split up what was originally one into a number of distinct tribes, are probably no more than distance and settlement in different parts of the country, leading to cessation of intermarriage and social intercourse.

The tribes have then obtained some variation in the original names or been given separate territorial or occupational designations by the Hindus, and their former identity has gradually been forgotten.

Both the Korwas of the Chota Nagpur plateau and the Korkus of the Satpura hills were known as Muasi, a term having the meaning of robber or raider.

The Korwas have also a subtribe called Koraku, and Mr.Crooke thinks that they were originally the same tribe.
