In 1869 The National Women's Suffrage Association was formed by Susan B. Anthony and Elisabeth Cady Stanton. It wasn't until the 19th amendment to the Constitution was passed in 1920 that all states ratified a woman's right to vote. Until then, only white males had the right to vote — and even then it was still selective. While the 15th ammendment extended the right to vote among black men in 1870, in practice they weren't actually allowed to vote until the 1960s with the passing of the Voting Rights Act.
In 1971, during the Vietnam War, the voting age was lowered from 21 to 18 to offset criticism that the men being drafted and sent off to war weren't allowed to vote for their leaders. This was the 26th ammendment.
Voting is an important privilege for all of us. It's a good time to get out, meet your neighbors for a cup of tea, vote and enjoy the day.
