How did world war i lead to the right to vote for us woman?

Okay. WW1, all the men were off to the battle field to fight so that only left the women. the women took over the men's job and started helping out. creating airplanes for battle and battle ships, one fun fact is that the women created more than what the men could create!and they were getting paid the same amount a man could make! this inspired many women to fight for women's right. They argued that women can work and be strong just like men! so when the men came back from war and took back their jobs. Women started standing up for women's suffrage. 

Freedom of religion, freedom of speech, being protected by our military and first responders on a daily basis and many many more.
