Modern Feminism.
For centuries women have been fighting to have equal rights as men. Throughout the 1950's women had been told throughout their life that their main goal was to keep the house running and to please the man of the house. This all started to change when Betty Friedan published the Feminine Mystique where it questioned being a housewives as all women were capable of doing. Within three years of the book being published a new feminist movement had begun.
In 1966 Friedan and other activists formed the National Organization For Women. The group was dedicated to "full participation of women in mainstream American society." Soon radical women had setup Freedom Trash Cans where women would throw away any object of female oppression. At this time for every dollar that men earned women would earn 59 cents. Also women would only constitute 40% of undergraduates but by 1980 they would constitute the majority of undergraduates.
With all of the activists fighting for women's rights also came to contraceptives which in many states had been outlawed. However, in 1965 the Supreme Court ruled these laws to be unconstitutional thus allowing them to be sold. They would again fight for the right for abortion which was also illegal in many states but in 1973 by a 7-2 vote that gave the women the right to have an abortion but this is still a widely debated topic to this day.
