Boxing dates back thousands of years. Today's bouts resemble those held at the ancient Olympic Games, where boxers wore leather straps wrapped around their hands to protect them. Boxing was introduced in the Olympics in 686 BC, but eventually the sport became too brutal -- the Romans developed violent versions of boxing which often ended in bloody deaths. By the late 1600s, boxing had become a professional sport in Europe, with money prizes going to the winners. Toward the end of the 19th century, Americans became interested in amateur boxing. The sport was practiced almost exclusively in the US and Britain at the turn of the century. It is no wonder that the US took every boxing medal at the 1904 Olympics -- all the competitors were American. In Olympic-style boxing, there are 12 different weight classes, ranging from 106 lbs. to 201+ lbs. Only men participate in Olympic Boxing. The list of Olympic Boxing Gold Medal winners who went on to become heavyweight champions includes Cassius Clay, later to become Muhammad Ali, Floyd Patterson, George Foreman and Joe Frazier. But the greatest Olympic boxer ever, never turned pro. Cuban Teofilo Stevenson won Gold three times, in 1972, 1976 and 1980, and probably would have won a 4th medal if Cuba hadn't boycotted the 1984 Los Angeles Games. While the US and Cuba have produced many, many Gold Medal winners (the US alone has won nearly 100 Boxing medals), great boxers have come from many countries on every continent through the years. The introduction of computerized scoring, which instantly tallies results and maintains databases to keep track of the judges' scoring patterns, has been designed to detect potential inconsistencies or biases, a not uncommon problem in Olympic Boxing events.
