According to experts, this style of fencing dates back 2,000 years, and began when men of the Mon race from the North took refuge in Siam and were organized into fighting units called Krom Darb-Song-Mu, or "Sword in both hands". These fierce warriors maintained their skills with constant training, following 10 basic positions which included standing on guard "dancing", "checking", "swaggering" and the actual clash of cold steel. The final blow usually led to the decapitation of the foe.

Besides it's deadliness in hand-to-hand combat, the art of fencing with two swords was regarded as a public display of skills and courage during feasts and festivals. These displays were held with the same ritual as modern Thai Boxing. The combatants wore costumes with talismanic figures on them and amulets around their heads. Pipes and drums were used to mark time during contest and whip the spectators into the same heady enthusiasm that you would see nowadays at Rajadamnern or Lumpini stadiums.

This same rhythm is captured in the Siamese tune "Muan Ram Dap" which was composed in honor of the Mon fighting tradition.

In more contemporary times, the famous royal heroes King Naresuan the Great and King Ekatathosarot were highly skilled in fighting with two swords and their art took a big toll of the Burmese invaders, who laid siege to the old Siamese capital, Ayutthaya, in 1586.

Thai sword-fighting held on as a national art and as a means of self-defense until about 200 years ago, during the reign of King Rama II, when the army was reorganized and equipped with modern musketry and cannon developed in the West.

Fencing schools now fence the Mon way, one of the most famous of which is the Sritrairat Camp located on the outskirts of Dhonburi, and the more famous fencing school is the Buddhai Swan in Ayutthaya.
