Bhargavas, also called Dhusar Brahmins, had their origin from the area near Dhosi Hill on the banks of Vadhusar river. Dhosi Hill is located in the ancient Vedic state of Brahmavarta, presently on the borders of Indian states Rajasthan and Haryana, area called Shekhawati. Part of 'Brahmavarta' state lies in South Haryana. Dhosi Hill is located 5 km from Narnaul and 60 km from Rewari. Bhargava community owe their lineage to Bhrigu Rishi, and his son Chyavana Rishi, who is better known for his links with creation of Chyawanprash by devas' Vaids, Ashwini Kumars the twin brothers.
Bhargavas are also called Dhusars, because of their origin from the Dhosi Hill area. They follow Vedic Sanskriti and Ayurved in their day to day life and believe in Vedic rituals. Bhargavas are a branch of 'Gaur Brahmins'. They are devout Hindus but in the past some of them have also followed Jainism.
Bhargavas had their descent from the ancient rishis (sages) Bhrigu and Chyavana. Bhrigu Rishi had contributed to many Sanskrit Holy books like Rigved, Taittiriya Upanishad, Manusmriti, Bhrigu Samhita etc. He is a revered saint in Vedic Sanatana Dharma and has several mentions in epic Mahabharat and various Puranas. He was contemporary of veteran Rishi Manu, considered to be a flood figure 10,000 years ago and had lived in the Vedic state of 'Brahmavarta' near Dhosi Hill. As per 'Bhargava Jati Ka Itihas', by religious historian, Dr. P.L.Bhargava, Parashuram was in the 39th generation of Bhrigu and was a contemporary of Bhagwan Ram Chandra and period of epic Ramayana. Parashuram was known as this, because he was carrying a 'farsa' all the time. Parashuram is also known as 'Bhargava Rama'.
The oldest known inscription mentioning the Dhusar community is at the Sakrai Mata temple in Sakrari in district Sikar that is dated by D.C. Sarkar to 879 AD, although it is dated by others to 642 A.D.
After a call from Adi Shankara during 840 AD, many Bhargavas took the appointments of 'Rajpurohits' with different ruling dynasties, mainly of Rajputs. Delhi, ruled by King Kumarpala had his 'Rajpurohit', Shyam Chandra from Qutabpur in Rewari. His descendants continued to be Rajpurohits of Delhi up to the year 1192 AD., the rule of Rajput King Prithvi Raj Chauhan, when his Rajpurohit was Priti Chandra of the same clan. Rule of Prithvi Raj Chauhan ended in 1192 AD when he was defeated by invader Muhammad Ghori.
They have a well established 'community associations', the 'Bhargava Sabhas', in various cities which act as community welfare associations. under an umbrella association 'All India Bhargava Sabha' presently located at Gurgaon in Haryana. There are around 37 of these Bhargava Sabhas[full citation needed] and their umbrella organisation is called the All India Bhargava Sabha, which was established in 1890 and to which all the Sabhas are affiliated.[full citation needed] The AIBS holds an annual conference at different cities in India - most recently at Jodhpur in November 2012 and Bikaner in December 2011 - and also international conferences in various countries to bring the wider community into the social and cultural mainstream.
