Agarwals are the descendants of King Agrasen. The icon of non-violence, messenger of Peace, Emperor Agrasen was the eldest son of King Ballabh of Pratapnagar. King Ballabh was a Suryavamshi ( lineage from the Sun). According to the Mahalakshmi Vrath, the age then was the last stages of Dwapar Yug. The birth of Maharaj Agrasen took place about 5185 years ago according to the current calendar. Even when he was very young, Prince Agrasen was well known for his compassion. He never discriminated against anyone and the subjects were very pleased with the way he conducted himself.
When Agrasen became a young man, he attended the Swyamvara of the daughter of the King Nagaraj, Princess Madhavi. In the Swayamvara, Princess Madhavi selected Prince Agrasen and married him. Agrasen went to the city of Kashi and started penance to propitiate Lord Shiva. Pleased with the severe penance of Agrasen, Lord Shiva appeared in front of him and advised him to propitiate Shri Mahalakshmi. Maharaj Agrasen began meditating on Shri. Mahalakshmi. Goddess Mahalakshmi was pleased with the dedication of Maharaj Agrasen and appeared before him. Goddess Mahalakshmi blessed Agrasen and suggested that he take up the Vaishya tradition of business for the sake of the prosperity of his people and give up his Kshatriya tradition. Additionally, she requested that he establish a new kingdom in return for her eternal presence with with his descendants. With the blessings of Sri Mahalakhmi, King Agrasen toured all of Bharat (India) . During his travels, he found a few tiger cubs and wolf cubs playing together. To King Agrasen and Queen Madhavi, this was an auspicious indication that the area was Veerabhoomi (land of the brave), and they decided to found their new kingdom at that location. The new kingdom was named Agroha. In due course, Agroha became prosperous and the influence of King Agrasen was felt in all neighboring areas as well. Trade, agriculture and industry flourished and the fame of King Agrasen spread far and wide. Maharaj Agrasen proceeded to conduct 18 Maha Yagnas. He divided his kingdom among his 18 children and established the 18 gotras after the guru's of each of his children. These same 18 gotras are like the eighteen chapters of the Bhagavadgita; although they differ, they are still related to each other to form the whole. Under this arrangement, Agroha prospered very well and flourished. In the latter part of his life, Maharaj Agrasen nominated his eldest son Vibhu to the throne and took up the Vanaprasth Ashram. Maharaj Agrasen, was king of great administrative skill. His concepts of kingdom and the duties of the king towards his subjects have evolved him as a centurial man. Equality, Nationalism, Socialism and Non-Violence were the principles which formed the backbone of his kingship.
It was maintained by Maharaj Agrasen that a nupital alliance could not take place in the same Gotra. That is a girl of "Goel" Gotra could not marry a "Goel boy"', but could be married in any of the other 17 Gotra. This rule enunciated by Maharaj Agrasen promoted harmony and brotherhood among all the 18 Gotra represented by state units. This facilitated promotion of unity and nationalism among the state units. Maharaj Agrasen was a doer (a Karmyogi) who conjured prosperity for all. An adherent of Socialism, he devised a unique rule in order to ensure an egalitarian society. He promulgated that any person coming to Agroha to settle down permanently, shall be given one rupee, one brick, by each resident of Agroha.With the bricks he could build a house for living and with the money so collected he could set up his own business. This way through a small help by each a person could attain a equal status in the society of equals.
