The FIE assists the International Olympic Committee in the organization of fencing events at the Summer Olympics. The number of events is a matter of contention between the FIE and the CIO since the introduction of women's sabre at the 1999 World Championships: since then, the World Championships feature twelve events–an individual and a team weapon for each of the three weapons, for men and for women. However, the CIO refuses to increase the number of Olympic medals allocated to fencing. After much dithering, the FIE decided to organize all six individual events, but only four team events decided on a rotational basis. The two team events excluded from the Olympic programme, one for men and one for women, compete instead in World championships.
