physical education director, William G Morgan created a game called Mintonette,
which latter developed what we call volleyball now. However
a game somewhat resemble volleyball played in 1591 in England.
The name 'Volleyball' came into light after an observer, Alfred
Halstead, noticed
the volleying nature of the game at its first exhibition match in 1896
at the International YMCA Training School (now called Springfield
College).

It was first introduced in 1956 by Dutch Sports Committee and only in 1979 it become an official international tournament sanction by International Sports Organisation for the Disabled. In 1980, men's sitting volleyball was introduced to the Paralympics Games and has grown to be one of the more popular sports in Paralympic Games due to the fast and exciting action. Women's sitting volleyball was added to the program for the 2004 Summer Paralympics in Athens, Greece.

Standing Volleyball was originally played only by amputees according to the variations of amputation. In 1984, it was decided to open up the game to allow other disability groups to take part, thereby encouraging more nations to participate.
