The Bias (or Vyas) are a Brahmin community found in the Indian states of Haryana, Punjab, Rajasthan, Uttar Pradesh and Delhi. They trace their origin to Gujarat.
The word bias means a preacher in Sanskrit. The Bias is an umbrella term for the members of the three Gujarati Brahmin communities named Nagar, Audichya and Bardai who migrated from Gujarat centuries ago and got settled in Haryana, Punjab, Uttar Pradesh, Delhi and Rajasthan. These three sub-communities of the group intermarry. They speak Haryanvi, Punjabi, Hindi or other local dialects. In Haryana, the community is found mainly in the districts of Bhiwani, Hisar, Sonepat, Rohtak, Jhajjar and Karnal.
The Bias are strictly endogamous and practice clan exogamy. Their clans are referred to as gotras, and theoretically all gotra claim descent from a respected saint or rishi. Among the larger gotras are the Gautam, Kaushik, Angira, Vashishta, Gargas, Bhargav, Bhardwaj, Parashar, Koshish, Monish, Sandal etc. that are further divided into sub-clans known as shashans. In some respects, they are regarded as the highest class of Brahmins.
