The idea for 50501 started as a Reddit post by user Evolved_Fungi in late January, quickly gaining traction on social media. 50501's first protest occurred on February 5, 2025. a group initially created to support
Bernie Sanders's 2016 political bid (not
Our Revolution, the political action organization founded as a continuation of Senator Bernie Sanders's 2016 presidential campaign). Political Revolution put up a live list and map of protests hosted by the 50501 movement shortly afterward. K Starling, of
We (the People) Dissent collected protests from four sites onto one list and an interactive map, for March 22–28 and April 5, 2025. The
Hands Off protests were hosted in 1,200 locations, including state capitals, major cities, and towns across the U.S. The movement announced that the next protests would take place on April 19 and that the protests would aim to involve 11 million people, roughly 3.5% of the population of the United States. On April 19, the movement hosted another rally in
Washington, D.C., and other locations in coalition with the
American Civil Liberties Union,
Indivisible,
MoveOn,
Color of Change, and the Women's March – a feminist organization that organized
the third largest protest in American history in 2017. 50501 remains active, hosting rallies, protests, and retaining a social media presence. Individual chapters communicate online and continue to organize "national days of action". 50501 helped organize the
2025 May Day protests in the US, the June 14
No Kings protests, which was reportedly the largest day of protest in modern US history, the
October 18 No Kings protests, and the still larger
third No Kings Day protests on March 28, 2026. == Reactions ==
