The historical origins of Krabi Krabong once accurately recorded for the prosperity and cultural heritage of the Thai people was lost when the plundering Burmese viciously destroyed the capital city of Ayutthaya. This reckless wanton destruction of one of the great cultural and religious centers of Asia included the demolition of temples, great works of art, religious artifacts and the royal archives of its closely guarded annals of medicine, science, art and martial culture. This brutal attacked mirrored the Mongol's own total decimation of the Burmese capital of Pagan, once the crown jewel of Burma's vast cultural center, over 400 years prior.
The origins of any martial culture can be clearly found within the nomadic tribes once called the Ai-Lao, which was a name given to the early Siamese race by the Chinese, who migrated from northern India through eastern Tibet and finally down into the Yunnan Plateau of China over 5,000 years ago. The scattered tribes after much turmoil and environmental evolution divided into three distinct groups: The Shans, The Ahom and the Lao-Tai. Each group spreading out into the regions later known as Burma, Laos, Thailand and Vietnam. The combative pressure of the Chinese, who referred to the Thai's as man (barbarians), was incessant.
The late Master Khetr Sriyabhaya described this difficult period, "They were constantly harassed and their peaceful existence disturbed until about 250 B.C., when they left the rich fertile land they called Muang Thaeng believed to have been the area of today's Szechwan, Hupei, Anwei and Hwang Ho in central China. In order to avoid enslavement, the Thais evacuated and dispersed in all directions. Eventually, and with great difficulty, encountering many hardships and having to cope with starvation, injury, disease and death, they became experts in what is today called traditional medicine. Fending off wild animals and all-too frequent battles with savage warlords who never missed a chance to attack, only strengthened their fighting spirit, and their love of freedom overcame all difficulties. Weakened, suffering severely and exhausted, they escaped."
