The 19th Amendment to the U.S. Constitution was passed by Congress in 1919 and guaranteed women's right to vote. It was considered by many Americans a radical change at the time, and it made it possible for all citizens to express their political views regardless of their gender.
The 19th Amendment was the result of a lengthy process during which several generations of women marched, lobbied, lectured and practiced civil disobedience to obtain the right to vote. The success of the campaign at the beginning of the 20th century was due to the changing role of women in American society.
