According to Mahabharata, Uttar was the crowned prince of Matsya Kingdom and the son of King Virata. Pandavas spent one year in their kingdom during their exile. His sister Uttara was got married to Abhimanyu, son of Arjuna.
When Duryodhana tried to attack the Matsya Kingdom, Uttar takes the help of his sister’s dancing teacher, Brihannala, who was actually Arjuna, who took the form of a dancer, in order to spend his exile period, without disclosing his original identity. He served as the Charioteer of Uttar and then he had shown his true identity in order to disclose his power to Uttar, and fought on behalf of him and succeeded in the war and defeated Duryodhana and drove him out along with the entire Hastinapura army. During the Kurukshetra war, Uttar fought with the Kauravas and supported Pandavas. But the great Uttar was killed in the battle by Shalya.
Prince Uttar was a pious man and after his death, he went to the Swarka Lok and living happily there by enjoying all sorts of comforts and luxuries and become a demi god in the heaven.
Let us worship Sri Uttar and be blessed.
