The idea for Solidarity Sundays came at the end of 2015, when three fed-up feminist friends (Kate Schatz, Leslie Dotson Van Every, and Jennye Garibaldi) got sick of having agonized political conversations and pointless social media arguments and decided to just DO SOMETHING. Our first meeting in January 2016 followed the mass shooting in San Bernardino, California, and we invited friends and neighbors to come over and take action on gun control. Over 60 people showed up, and in one day we made almost 1,000 phone calls/emails to President Obama, VP Biden, AG Lynch, and many pro-NRA California Reps. Inspired by the feeling of working together to speak up and make a difference, we kept meeting every month to take action together.

In the wake of Trump’s election in 2016 we held an emergency meeting. Almost 100 people attended, and within two weeks we'd organized chapters all over the country. People across the country were inspired by the focus of Solidarity Sundays: creating a simple way to come together, learn from each other, and ACT.

The group’s original name was Suffragette Sundays, since we were focused on engaging women in political action. We heard feedback that the name felt problematic because of the racist history of many in the Suffrage movement; we listened, agreed, and changed the name to something more inclusive and indicative of what is needed most right now: SOLIDARITY and ACTION.
