The ancient martial art of Tang Soo Do can be traced back as far as when Korea was divided into three kingdoms: Koguryo Dynasty, Silla Dynasty, and Paekche Dynasty. This era lasted from 57 BC to 935 AD. Tang Soo Do was commonly used as a way of self-defense in warfare as evidenced by many ancient paintings and artifacts. Out of the three dynasties, the Silla Dynasty was said to have developed Tang Soo Do the most. However, when the Japanese occupation began in 1909, practicing any form of Korean martial arts or cultural activities was banned. After the occupation was over in 1945, many Tang Soo Do schools began to appear throughout Korea. Today, the authentic Korean martial art of Tang Soo Do is practiced throughout the world.
