The first womens' game played at Smith College, 1892. The full court game was thought too strenuous for young females. Initially the rules for women were very different, calling for a '3 court' version. The playing floor was divided in three and each team had players in each section. These players could only be in those sections, only a couple could score.
In 1914 the rules changed, the two-court game was now what women were allowed to play. Five, then six players a side, restricted to their zones of play. In most states, a player could only use two dribbles before passing or shooting. Until the early 1940s, guards could not guard a shooter. Some states eventually allowed a rover, a player allowed to play in either zone.
Iowa allowed the full court game in 1983, but the 6 player game lasted in that state to 1993. Oklahoma as well played the two court until 1993, albeit with unlimited dribbles. The last state to abandon High School 6-woman basketball was Indiana in 1993-94.
Here are the high scoring game records for the state of Missouri during the 6 on 6 era:
