Kol people
The Kols, also known as Kolarians, are the original inhabitants of modern-day West Bengal and North-east India. The term Kol has been corrupted by the Aryan-Sanskritic speakers to the word "kalu", meaning both "black" and "ugly", in almost all of the 16 major languages of the subcontinent. The Kolarians are a Dravidian peoples stock group, whose descendant communities can be found also in West Bengal and elsewhere in the eastern part of the East India.
