Jiu jitsu

don't think anyone can answer this question with certainty, but there are plenty of good hypotheses. Every culture has some form of hand to hand combat in its history. Combat without weapons usually appears in the form of wrestling and sometimes boxing. Looking at the history timeline, one good hypothesis is that the wrestling techniques of Jiu-Jitsu could very well have come from Ancient Greece. Olympic games were one of the Greek's strongest traditions. It is most likely that along with Greek ideas, came one of its most popular sports, Pankration. Pankration was a sport that involved both boxing and wrestling techniques and became more popular to the Greeks than either of those sports individually. Pankration would later be overshadowed by the Roman Gladiators, and then banned from the Olympics by Christian leaders of the Roman Empire. Even though new rulers would come and go, Greek customs and ideas still reached India, where Jiu-Jitsu's foundation was likely to have been born. During Alexander the Great's conquests (356 - 323 B.C.), he brought the Greek culture to the areas he conquered. His conquests stretched all the way to India, where he introduced the customs and ideals of Greek culture to the people of that area. Jiu-Jitsu wasn't being formally taught in Japan for over one thousand years after this. Many say that the Greek influence in India led to the development of Kung Fu or more appropriately, Wu Shu (martial arts) in China.
