Warli

The Warlis or Varlis are an indigenous tribe or Adivasis, living in mountainous as well as coastal areas of Maharashtra-Gujarat border and surrounding areas. They have their own animistic beliefs, life, customs and traditions, as a result of acculturation they have adopted many Hindu beliefs due to Brahminical Sanskritisation. The Warlis speak an unwritten Varli language which belong to the southern zone of the Indo-Aryan languages.

Warlis are found in Jawhar, Dahanu and Talasari talukas of the northern Thane district, parts of Nashik and Dhule districts of Maharashtra, Valsad, Dangs, Navsari and Surat districts of Gujarat, and the union territories of Dadra and Nagar Haveli and Daman and Diu.

The Warli speak in Varli language, classified as Konkani, with some degree of influence from Gujarati.
