Middle Ages

When the Islamic rulers of Persia began hiring Turkic mercenaries about 800 CE, the soldiers brought with them a style of loose wrestling called koresh, in which grips may be taken on the long, tight leather pants worn by the wrestlers and the bout ends with a touch fall of the loser briefly on his back. Gradually the Turks took over the entire Muslim dominion, and their wrestling style spread. Later Mongolian invasions in the 13th century introduced Mongolian wrestling, which received royal patronage, and wrestling became the national sport of modern Iran.

Sumo, a Japanese belt-wrestling style, was a popular spectator sport under imperial patronage (710–1185). Originally a submission spectacle, sumo became highly ritualized as a toppling match with victory coming also from the forcing of an opponent out of a 12-foot (4-metre) circle. By the 17th century sumo wrestling had became a professional sport in Japan. From the samurai martial art jujitsu, judo, the other prominent Japanese wrestling style, was derived in the 19th century and became an international sport in the second half of the 20th century.
