Jigoro Kano makes a comprehensive study of the ancient self-defence forms and integrates the best of these forms into a sport which becomes known as kodokan judo. The term kodokan breaks down into ko (lecture, study, method), do (way or path), and kan (hall or place). Thus it means "a place to study the way". Similarly judo breaks down into ju (gentle) and do (way or path) or "the gentle way".

1882

The categorisation of kodokan judo is completed. The kodokan had three broad aims: physical education, contest proficiency and mental training.

1887

Proceeding with the organisation of the kodokan and enacting the regulations of judo, Kano becomes the first Asian member of the International Olympic Committee and works for the spread of judo worldwide.

Kano is awarded the Asahi Prize for his outstanding contribution to the organising of sport in Japan during his lifetime.

1951

Japan's Risei Kano, son of Jigoro, takes over as IJF President.

1952

Judo becomes an official event in the Olympic Games of Tokyo, backed by judo fans and sport promoters all over the world. Medals were awarded in four classes, and competition was restricted to men only. The competition was held in the Nippon Budokan, which was built to host the competition. Japanese victories for lightweight Takehide Nakatani, middleweight Isao Okano and heavyweight Isao Inokuma put them top of the medals table. The Netherlands' Anton Geesink wins the open category.

British Judo Association President Charles Palmer assumes the equivalent role within the IJF.

1965

Judo is omitted from the sports programme of the Olympic Games in Mexico City.

Medals are awarded in five weight classes at the Olympic Games in Montreal, where Japan top the medals table with three golds.

1976

Japan's Shigeyoshi Matsumae becomes the fourth President of the IJF.

1979

Judo competition at the Olympics in Moscow marks the first time that the medal table was not dominated by Japan, since the country joined the boycott of the Games because of the Soviet invasion of Afghanistan the previous year. Medals are awarded to male judoka in eight competitions, seven weight classes and the open competition - two more than in 1976. All events were held at the Palace of Sports of the Central Lenin Stadium. The Soviet Union and France claim two gold medals each, while East Germany, Belgium, Italy and Switzerland earn one apiece.

1980

Judo competition at the Olympics in Los Angeles continues the seven weight classes first used at the Moscow 1980 Games. With the open division, there are eight competitions, which are restricted to male judoka. Japan returned to the top of the medal table, after boycotting the Moscow Games. Because of the Soviet-led counter-boycott of the Los Angeles Games, several traditionally strong judo countries, including Cuba and the Soviet Union, do not participate.

1984

Argentina's Sarkis Kaloghlian becomes the fifth President of the IJF.

1987

Women's judo makes its first appearance at the Olympic Games, as a demonstration sport in Seoul. Japan failed to claim top spot in the medal table for the first time in an Olympics in which they participated, coming third behind South Korea and Poland. Austria's Peter Seisenbacher and Japan's Hitoshi Saito defend their respective middleweight and heavyweight titles from 1984, and become the first judoka to win gold at two Olympics.

2000

Judo at the Olympic Games in Athens takes place at the Ano Liossia Olympic Hall, where 368 judoka compete for 14 gold medals with seven different weight categories in both the men's and women's competitions. Japan dominate the event by taking eight gold and two silver medals. There is controversy in the men's competition, when Iranian competitor and two-time world champion Arash Miresmaeili weighs in overweight and is disqualified before a match in which he would have faced Israeli judoka Ehud Vaks. Miresmaeili's comments strongly suggested that he had intentionally disqualified himself so as not to compete against an Israeli. "Although I have trained for months and was in good shape I refused to fight my Israeli opponent to sympathise with the suffering of the people of Palestine and I do not feel upset at all," he says.

2004
