It’s hard to believe that in a country founded nearly 250 years ago, women have only been allowed to vote for a little over 100 years.

But that’s what we’re celebrating today, in equal measure: How far we’ve come, but also how far we’ve left to go.

Honestly, it pretty well encapsulates our mission here at Women’s March.

We know that when we come together and organize, when we take to the streets and make our voices hard, when we speak out against injustice and fight for what we know is right — we can win.

We’ve recently had some huge victories in places like Wisconsin and Ohio, but we know that anti-choice extremists and far-right bigots are only ramping up their attacks on reproductive freedom, and we have to be ready to fight back with everything we’ve got, at every turn, in every state.

Today is a celebration of what we’ve accomplished to improve circumstances and opportunity for women, but it’s also a recognition that not only is there more work to be done, but that it won’t happen on its own.

Our promise to you, John, is that Women’s March will always be ready to take to the streets, mobilize, and fight on behalf of women, equality, and justice. If you support Women’s March and you’d like to contribute to our mission, you can do so below.

Thank you, and Happy Women’s Equality Day!
