#ReclaimOurHistory  #VoteOurFuture


"Dendrofemonology offers itself as a bullseye for collective action."Ms Magazine Sept 2023

Join us Nov 1-4, in person or online, as we gather around a new kind of monument -- DENDROFEMONOLOGY: A Feminist History Tree Ring by artist Tiffany Shlain -- for 4 days of art and action, inspiring speakers, voter and educational resources, a feminist art parade, community, coalition-building, and more!  

There are 93,000 races on the ballot this November that could affect women’s rights, trans rights, and reproductive freedom. Our goal, with an incredible coalition (ERA Coalition, Planned Parenthood Action Fund, Vital Voices, Feminist Majority Foundation, SheThePeople, and many more) is to inspire and galvanize people with this intersectional coming together, to stand together as allies, and #ReclaimOurHistory and #VoteOurFuture. We would love for you to join us, either in person or online via livestream!

Presented by
The National Women's History Museum, Women Connect4Good, and Let It Ripple​

In Partnership with an amazing coalition of organizations:

ERA Coalition | Planned Parenthood Action Fund | Vital Voices | Feminist Majority Foundation

She The People | Take The Lead | Equality Now | Supermajority | Female Quotient 

World Wide Women | Vote Pro Choice | The Feminist institute | A Tour of Their Own | and more



Key Components of Activation:

  • Voter Registration, Education, and Activation: Registers, educates, and inspires voters, particularly young voters, with guides and materials for any region. 


  • Live & Virtual Events: Nov 1-4 will be a series of live and livestreamed events on the National Mall including powerful speakers, workshops, a silent disco, an art parade, and tours of The National Women's History Museum exhibition We Who Believe: Black Feminism DC exhibition at the MLK Library in DC.


  • Speakers/Livestream: On November 1, a series of powerful speakers will kick-off the activation, speaking directly in front of the Feminist Tree Ring, in the dramatic setting of the Washington Monument. We will livestream and amplify these speakers through all of our, and our partners’, channels. 

  • Educational Resources: The National Women’s History Museum has started a resource that links out from each of the lines on the Feminist History Tree Ring. Together with NWHM, we will build upon this resource, to link out from each and every line on the tree ring, and make it widely available to schools and the public. 

  • Powerful Coalition: Building off the model of 50/50 Day (watch 3 min video about the activation that engaged millions), this activation brings powerful organizations together for a collective activation

  • Participation / Inspiration: Everyone will be invited to answer: What’s a line on the tree ring that has helped pave the path for you, and why? What is an event not on the timeline that has paved a path for you, and why? What do you hope we vote onto the tree ring next? We will create further art from these responses, while simultaneously, these questions build the civic engagement muscle for both the 2023 and 2024 elections.

DENDROFEMONOLOGY: A Feminist History Tree Ring

“I have always been fascinated by the tree ring timelines at the entrance of Muir Woods or any National Park. They illuminate how the trees are a witness to human history. However, I also felt like those timelines tell a colonialist and patriarchal story. The tree rings in Human Nature imagine what alternate histories could be told.”- Tiffany Shlain
