Answer:
1920 was the year when women gain the right to vote
19th amendment
Step-by-step explanation:
The 19th Amendment states that the right to vote "shall not be denied or abridged by the United States or by any State on account of sex." In theory, this language guaranteed that all women in the United States could not be prevented from voting because of their gender. In reality, a continual disregard for the 15th Amendment--which had been ratified 50 years earlier and banned voter discrimination based on race--created a loophole to prevent black women and other women of color from voting on account of their race.
Passed by Congress June 4, 1919, and ratified on August 18, 1920, the 19th amendment granted women the right to vote. The 19th amendment legally guarantees American women the right to vote. Achieving this milestone required a lengthy and difficult struggle—victory took decades of agitation and protest.
