Banasura (बाणासुर) or Bana was a thousand-armed Asura and son of Bali. Banasur was a powerful and terrible asura. Non Aryan Kings in that age were termed as Asuras or daityas. All people even the king of earth and Devas of heaven were afraid of him. Bana was a follower of Shiva. Banasura ruled with his capital at Sonitpur. .

Jat Gotras from Banasura
There are several legends associated with Banasura. According to a legend, Banasura had obtained a boon from Lord Shiva that he could be vanquished only by a virgin, unable to bear the harassment of the asura king, Shakti, the supreme Goddess was requested by the Devas to destroy Banasura who was creating havoc on the inhabitants of this world. In Shakti appeared as a young virgin girl at Kanyakumari and commenced penance in answer to their Prayers.
Another legend is that Sthanunatha (a form of Shiva) god of Suchindram, a nearby town located 12 km from Kanya Kumari, desired to marry the virgin goddess. Other gods became apprehensive that the marriage would result into the goddess losing her power. Narada schemed to resolve the problem. The marriage was fixed to be solemnized just before the daybreak. When Shiva's procession reached a site by name Vazhukkumpaarai, a rooster crowed, heralding daybreak, and that Shiva assuming that the auspicious hour was past, returned to Suchindram. All the food prepared for the wedding was laid waste and that it turned into the colored sand seen on the southern shores of the subcontinent.
Meanwhile, Banasura heard about the beauty of the girl and came to request her hand in marriage. When Devi rejected the idea, Banasura decided to win her by force. This led to a fierce battle in which the goddess killed Banasura. 
The ancient Multan city of Punjab is known by different names, but one of its oldest name according to Cunningham, was Kashyappur . It was founded by Kashyapa.

At the same time Krishna killed Banasura and later Krishna's son Samba became the king of Kashyapapur.

Genealogy of Banasura
The genealogy of Banasura is as under:
Usha in love with Aniruddha
Banasura had a beautiful daughter named Usha. When Usha became young, number of proposals came for her marriage but Banasura accepted none. Wary, that Usha might fall in love with men other than his choice, he kept Usha in a formidable fortress called 'Agnigarh 'with her friends. Usha one day saw a young man in her dream and fell in love with him. Chitralekha was a friend of Usha and daughter of Kumbhada, minister of Banasura. She was a talented artist who helped Usha to identify the young man seen in the dream of Usha by painting the portrait. He was Aniruddha, the grandson of Lord Krishna. Chitralekha through supernatural powers abducted Aniruddha from the palace of Krishna and brought him to Usha. Usha and Aniruddha secretly married and lived together as husband and wife in the Agnigarh.
War of Banasura with Krishna
When Banasur came to know about it, He arrested Aniruddha and had him tied with snakes. When Krishna knew it, he came with a huge army and attacked Banasura. This was Krishna's second visit to Assam, the first being when He came to abduct Rukmini, his wife. There was a severe battle. Banasura was a follower of Shiva. In this war Rudra fought with Krishna, Virabhadra with Pradyumna, Kopakarna and Kumbhada with Balarama, Banasur's son with Samba and nandishwar with Garuda. Shiva helped Banasura by spreading bacteria of fever in the army of Krishna, which made his army unable to fight. Krishna in turn created anti-bacteria to kill bacteria spread by Shiva. All soldiers of Krishna’s army got healed up and became ready to fight. The war continued for long without any conclusion. Krishna then approached Shiva and reminded him of his earlier commitment. Shiva advised Krishna to use Jambhastra on him which would lead Shiva to sleep and Krishna could defeat Banasura. This way Banasura was defeated. When Krishna defeated Siva in battle, he spared Bana's life on Shiva's request but cut off all but four of his arms. Shiva got compromised both. Krishna excused Bana. He married Usha with Aniruddha and brought them to dwaraka. Banasura moved to Himalayas and devoted his life in worship of Shiva.

जाटों का विदेशों में जाना
ठाकुर देशराज ने लिखा है .... उत्तरोत्तर संख्या वृद्धि के साथ ही वंश (कुल) वृद्धि भी होती गई और प्राचीन जातियां मे से एक-एक के सैंकड़ों वंश हो गए। साम्राज्य की लपेट से बचने के लिए कृष्ण ने इनके सामने भी यही प्रस्ताव रखा कि कुल राज्यों की बजाए ज्ञाति राज्य कायम का डालो। ....द्वारिका के जाट-राष्ट्र पर हम दो विपत्तियों का आक्रमण एक साथ देख कर प्रभास क्षेत्र में यादवों का आपसी महायुद्ध और द्वारिका का जल में डूब जाना। अतः स्वभावतः शेष बचे जाटों को दूसरी जगह तलाश करने के लिए बढ़ना पड़ा। .... बाना लोगों ने ईरान के देश में जाकर बस्ती आबाद की जहां उनके नाम पर ही उस नदी का नाम मशहूर हो गया जिसके कि किनारे वे जाकर बसे थे। भारत में बाणगंगा के किनारे से उठकर गए थे जहां पर कि आजकल बयाना आबाद है। उषा इन्हीं लोगों की पुत्री थी। कृष्ण से लड़ने के कारण भक्त लोगों ने बान लोगों के सरदार को बाणासुर कहा है किंतु बात ऐसी नहीं है। कंस, बान, दंतवक्र यह सब चंद्रवंशी थे असुर नहीं थे। कुछ लोग मानते हैं कि स्कैंडेनेविया को बान के लड़के स्कंद ने आबाद किया था।
