The most famous part of Kung-Fu's history dates from sometime in the sixth century AD with the arrival of an Indian Buddhist monk, Bodhidarma, at the newly formed Shaolin Temple. Buddhism had been brought to China a few hundred years before but Bodhidarma brought the new religion to the martial arts. Whether or not the monks at Shaolin were already versed in the martial arts and what exactly Bodhidarma taught them, is much disputed. The result, however, is not. Shaolin monks dedicated themselves to Kung-Fu and became a warrior elite whose fame spread throughout China. They were engaged in countless military campaigns and are credited as bringing peace to their own bandit-ridden province. By the 17th Century Kung-Fu experts travelled from far and wide to learn their secrets. Shaolin Kung-Fu is extremely demanding on the body. Only by dedicating themselves to hours of rigorous daily training could the Shaolin rise above the feats of ordinary men. Around the same time, rival Taoist monasteries, such as the one on Wudang Mountain, taught different styles of Kung-Fu, classified as internal.
