Although originating from North Africa, boxing has become a worldwide sport, followed by many fans in every continent. Its biggest fan base is in America and Europe.
In the early days, boxing was illegal in USA, but after the State of New York legalized it in 1896, the other states followed. The main body of boxing is the American Boxing Association (ABA), which organizes tournaments and awards championship belts. America has produced and still produces many of the biggest names in boxing, such as Muhammad Ali and Mike Tyson.
The biggest rival of America in boxing competitions is, of course, Europe. The European Boxing Union, known to fans as EBU, oversees the development of boxing in the continent, and also implements the rules.
