Text Box: History of Muay Thai 

Modern Thai Boxing (Muay Thai) originated from Krabi Krabong, a Thai weapons art roughly translated in "stick and sword". When the Thais lost their weapons or fought close quarters with weapons they used knees, elbows, feet, fists and head butting and they became famous for their toughness on the battle field in constant wars with their Burmese rivals.

King Ramkamheng (1275 - 1317) wrote the "Tamrab-Pichei-Songkram "The Book of War Learning" about the Thai war art. The basis of weapon less fighting. 
This art, which was included in military training, was made famous by King Naresuan (1560 A.D.). During one of the many battles between Burma and Siam ,he was captured. The Burmese knew of his name as the best unarmed fighter in the realm and gave him a chance to fight with their champion for his freedom. Naresuen is said to have won and became a national hero. 
The biggest Thai boxing hero of Thailand is the 'Black Prince' Nai Khanom Dtom, who was captured by the Burmese and had to fight against 12 of the best Burmese fighters before he was released. Against all odds the Burmese crowd themselves had forced the King of burma to set him free. Upon his return to Siam he was hailed as a hero and Siamese-style boxing, as it was called then, was soon recognized as a national sport.
The Thais are still having annual Muay Thai tournaments in order to salute him. 
Towards the end of the 18th century, a king named Pra Chao Sua trained religiously in the art of Muay Thai. He was reputed to have trained six hours a day with his soldiers to perfect his art. Every village of that time would have prize matches with everyone competing; young and old, rich and poor. The king would disguise himself as a peasant and sneak out, village to village entering the tournaments and defeating all takers. He would spend hours by himself perfecting his techniques, and then test them in the village tournaments. His nickname became the Tiger King. So great was his legend that even today his techniques still exist and are known as the Tiger King style.

In the old days the fights lasted until one of the fighters was dead or seriously injured. There were no rounds and the fights could have lasted for several hours. No protective gear was used and sometimes they wore rope over their knuckles and glued some broken glass on top of it... 

Before 1929, Thai fighters fought bare-knuckled. In 1929, Muay Thai was slightly reformed with a few rules to help protect the fighters. The Thai government became concerned due to the high number of fatalities in the ring and forced some rules to be used: They gave up groin shots, eye pokes, started using weight classes and boxing gloves, and rounds. The Thais felt that this watered down their sport. As a result, Thais place more emphasis on kicks, particularly to the legs; knee strikes; and grappling. These skills score higher points than hand strikes in Thai matches. 

What exactly is Thai boxing? 
Muay Thai involves boxing techniques, hard kicking, and knee and elbow strikes. Low kicks to the thighs are a very distinguishing technique used frequently in Muay Thai. Stand up grappling is also used and allowed in the ring. Muay Thai practitioners develop a very high level of physical conditioning developed by its practitioners. 

About Training and physical abilities
The training involves rigorous physical training, similar to that practiced by Western boxers. It includes running, shadow-boxing, and heavy bag work. Much emphasis is also placed on various drills with the so-called "Thai pads". These pads weigh five to ten pounds, and cover the wearers forearms. In use, the trainer wears the pads, and may hold them to receive kicks, punches, and knee and elbow strikes, and may also use them to punch at the trainee. This training is vaguely similar to the way boxing trainers use focus mitts. The characteristic Muay Thai round kick is delivered with the shin, therefore, the shins become conditioned by this type of kicking. 
Full contact, full-power sparring is usually not done in training, due to the devastating nature of the techniques employed. Thai boxers may box, hands only, with ordinary boxing gloves. Another training drill is for two fighters to clinch, and practice a form of stand-up grappling, the goal of which is to try to land a knee strike. However, full-power kicks, knees, and elbows are typically not used in training. 
Promising children will enter dedicated Muay Thai training camps as young as six or seven. There, the fighter will be put on a plan aimed at making him a national champion while still in his teens. The Thais fight frequently, and a 20 year old fighter may have had 150 fights. Typically, half the purse from each fight goes to the training camp, with the remainder being split between the fighter and his family.
