50501 movement

50501 (short for "50 protests, 50 states, 1 movement") is an American progressive grassroots political organization founded to organize the 50501 protests against policies and actions of the second Donald Trump administration in the United States.

The group organized several nationwide demonstrations starting on February 5, 2025, with anti-Trump rallies. The group hosted another nationwide protest—named "No Kings on Presidents Day"—on February 17 (Presidents' Day), and a third demonstration on March 4, 2025. The movement's membership contributed to the organizing of the April 5, 2025, Hands Off protests, which gathered millions of participants nationwide and was among the largest protests against U.S. president Donald Trump.

"No Kings" protests took place across the US (but avoided Washington, D.C.) on June 14, 2025, the day of the U.S. Army 250th Anniversary Parade and Donald Trump's 79th birthday. These events were held in over 2,000 locations and attended by an estimated 5 million people. As part of the No Kings Coalition, 50501 worked with 200 other organizations to organize the follow-up October 2025 No Kings protests at over 2700 locations around the country on October 18, 2025. Organizers of the protest estimated that nearly 7 million protested nationwide, making it the largest single-day protest in US history. Organizers have announced that the next No Kings Day will take place on March 28, 2026.

The movement continues to hold demonstrations and organize mutual aid efforts nationwide and is active online, locally, and nationally.
