The United States of America has been a nation governed by the Constitution for 226 years. That's two centuries of change, evolution, and progress -- that continues to this day.

The just-announced decision that the Department of the Treasury would replace Alexander Hamilton on the $10 bill is the latest in the slow, staggered series of gender-equality milestones that began when the country was substantially younger. Perhaps the first was the decision by Wyoming in 1869 to grant women the right to vote. Then women gained elected local elected office, the right to suffrage nationally, admittance to Congress, seats in the Cabinet and positions on presidential tickets. Many of these advances are very recent; the first Hispanic woman elected to Congress was Rep. Ileana Ros-Lehtinen, who won her seat in 1988, for example.

How recent? Enter your birth year to see.

And below, a timeline of the major events included above, in which American women achieved something political that American men had long taken for granted.

(Note: We included Sally Ride mostly because it was so cool.)

Given that this is a politics blog, we'd be remiss if we didn't call attention to the possibility that, by this time next year, we'll likely be able to add "First woman major party nominee for president." And we fully expect people to point out the possibility of another big milestone shortly thereafter.
