Indian Aboriginal Tribes are the ethnic inhabitants of the country, who have been termed as "Scheduled Tribes" in the Indian Constitution and are scattered throughout India. The aboriginal tribes of India have been following their individual series of ancient traditions, cultures and customs since times immemorial.
