Son of Radha, a name of Karna, who as a foundling was brought up as a son by Radha, the wife of the Charioteer Adhiratha.
Karna (IAST transliteration: Karṇa), originally known as Vasusena, is one of the central characters in the Hindu epic Mahābhārata, from ancient India. He was the King of Anga (present day Bhagalpur and Munger). Karna was one of the greatest warriors, whose martial exploits are recorded in the Mahābhārata and the only warrior believed to be able to defeat Arjuna in battle, an admiration expressed by Lord Krishna and Bhishma within the body of this work. As per Mahabharata, Karna was the only warrior in that era who conquered the entire world. Karna was the only warrior in the Mahabharata who single-handedly successfully conducted Digvijaya Yatra, conquering all kings in every direction of the world in order to establish Duryodhana as the emperor of the world and to conduct the Vaishnava sacrifice.
Karna was the son of Surya (a solar deity) and Kunti. He was born to Kunti before her marriage with Pandu. Karna was the closest friend of Duryodhana and fought on his behalf against the Pandavas (his brothers) in the famous Kurukshetra war. Karna fought against misfortune throughout his life and kept his word under all circumstances. Many admire him for his courage and generosity. It is believed that Karna founded the city of Karnal, in present Haryana. Karna, Mahabali, Harishchandra are the three most famous personalities in Hinduism based on the merits they earned by giving charity. They are often quoted for their sacrifice, courage, charity, valour and selflessness they exhibited for helping a fellow being.
