The change in the art was to continue under another fighting King - Prachao Sua - the Tiger King. From the history of Muay Thai, he loved Muay Thai so much that he often fought incognito in village contests, beating the local champions. During the reign of the Tiger King the nation was at peace. The King, to keep the army busy, ordered it to train in Muay Thai. The interest in the sport was already high but now it took off yet again.

Thai Boxing became the favorite sport and pastime of the people, the army, and the King. Historical sources show that people from all walks of life flocked to training camps. Rich, poor, young and old all wanted some of the action. Every village staged its prize fights and had its champions. Every bout became a betting contest as well as a contest of local pride. The betting tradition has remained with the sport and today large sums are wagered on the outcome of fights.
