As the story is told through Thai folklore, during the time of the falling ancient Siamese capital of Ayutthaya Kingdom in 1767, the Burmese King Hsinbyushin(known in Thai as King Mangra), rounded up thousands of Siamese and moved them to Burma as prisoners. Among the taken were a large number of kickboxers. One of those captives was a Muay Thai fighter named, Nai Khanom Tom. At one point, King Hsinbyushin wanted to see how Muay Boran would compare to Burmese Lethwei, or Burmese Boxing.
