Muaythai has been a part of Thai history and heritage for hundreds of years, as with most traditions from ancient times. Many different versions of the history of Muaythai exist, but all sources agree that Muaythai was the primary and most effective method of self defence used by Thai warriors on the battlefields of conflicts and wars that occurred countless times throughout the history of the nation now known as Thailand. During this time, a warfare manual named “Chupasart” was written. This manual emphasised the martial uses of each body part. The underlying philosophy of this manual implied that fighting was more than the use of weapons, but most importantly, should engage total commitment from mind, body and soul.
