Judo History
Judo developed out of ju-jitsu introduced into Japan by a Chinese monk, Chen Yuan-ping in the early seventeenth century as a form of unarmed combat. In the days of chivalry, several ju-jitsu schools evolved where the young samurai were taught the art.
Earlier Samurai Warriors used to carry swords and were also proficient in the art of ju-juitsu. In 1871, bearing of swords was prohibited. With the intention of spreading judo beyond Japan, Kano arrived in Europe 1889. He was accompanied by a judo exponent Yukio Tani, who presented a brief display of the art in Britain. At the turn of the century, Yamashita, another Kano pupil, joined the movement and started giving instruction in the United States. He even taught the sport to President Roosevelt. The Paris police were also given lessons of judo as a form of self-defense. In 1928, Shinzo Tagaki, another pupil of Kano, spread the art to Australia and in 1929, he brought it to India. It arrived in Africa two years later. Many Europeans travelled to Japan during the 1930s. Trevor Leggett was the first British to make the trip in 1938.

Though judo gained popularity exponentially across all the continents, it was always looked upon as a means of self-defense and not a sport. However, after the end of the Second World Wart it developed into a competitive sport. In 1948, the European Judo Union was founded. Three years later, in 1951, the International Judo Federation was constituted.
