Wikipedia
Korfball is a ball sport, with similarities to netball and basketball. It is played by two teams of eight players with either eight females in each team or with four females and four males in each team. The objective is to throw a ball through a bottomless basket that is mounted on a high pole.
The sport was invented by Dutch school teacher Nico Broekhuysen in 1902. In the Netherlands, there are around 580 clubs and over 100,000 people playing korfball. It has a mixed-gender league and an all-women league, but no all-men league. The sport is also very popular in Belgium and Taiwan, and is played in many other countries. Mixed-gender korfball is more generally played in the north of the Netherlands, while all-female korfball is generally played in the south.
