Thailand’s capital was situated at Sukhothai from around the Buddhist years 1781-1951 (1238-1408 CE). Inscriptions in stone columns at Sukhothai indicate that Sukhothai fought with its neighbors quite often. Consequently, the city had to instill in her soldiers knowledge and skills concerning the use of weapons such as swords and spears, and also how to use the body as a weapon in situations of close person-to-person combat. Skills such as kicking, kneeing, punching, and elbowing were thus developed.
During peacetime, young men in Sukhothai practiced MuayThai to build character and their self-defense skills. These skills would serve them well during their time in the military and thus the practice of MuayThai became a good custom. MuayThai training centers arose around the city, for example, the Samakorn Training Center in Lopburi. Some were in temple areas where monks doubled as instructors.
