The championship started in 1974 in Havana, Cuba as men's only sport but later opened up for women 25 years later in 2001. The competitions are hosted separately, with the men's and women's occurring in alternating years.

As of 2023, there are 13 classes for men and 12 for women.

"The World Boxing Championships represent the pinnacle of amateur boxing competition, showcasing the technical skill and athletic prowess that defines the sport at its highest level."

💡 Pro Tip: Weight classes allow boxers of similar size to compete fairly, ensuring matches are determined by skill and technique rather than physical advantage.

This boxing match is scored round by round. The fighter with the most points win. Each time an opponent is knocked down, they lose a point. Immediate victories are determined by a complete knock-out.

The competition uses medals to award participants. Currently, Russia has dominated this competition by winning the most medals, their women are ranked first while the men are ranked second.
