Mankind has been swimming since prehistoric days. However it was not widely practiced until early in the 19th century, when the National Swimming Society of Great Britain began competitions. Most early swimmers used the breaststroke, or a variation of it.
The first version of the crawl stroke was based on a native South American stroke & features a scissor kick. Late in the 19th century an Englishman named Frederick Cavill travelled to the South Seas, where he saw the crawl with a flutter kick. Cavill later settled in Australia, where he taught the stroke that become the Australian crawl.
Swimming has featured in the Olympics since 1896. The very first competitions were freestyle (crawl) or breaststroke. Backstroke was added in 1904.
In the 1940s, breaststrokers discovered a new stroke that allowed them to move faster through the water. The stroke was forbidden in breaststroke, but became the butterfly stroke. This is now one of the four strokes used in competition.
