The No Kings protest is a large-scale, nationwide series of demonstrations mainly in the United States against the authoritarian policies and actions of President Donald Trump's administration during his second term, which began in January 2025. The protests, also known internationally as the No Dictators or No Tyrants protests, originated with the "No Kings Day" on June 14, 2025, which coincided with Trump's 79th birthday and the U.S. Army's 250th anniversary parade. The movement is organized by the 50501 coalition (representing 50 states, 50 protests, one movement) to reject what they describe as autocratic governance, billionaire-driven politics, and militarization of democracy under Trump's leadership. Participants in No Kings protests symbolically reject the idea of Trump acting like a king or dictator rather than a democratically elected president. Organizers advocate nonviolent resistance and view the protests as a defense of democratic institutions, the constitution, and American republican values. The protests have involved millions of people across thousands of cities, towns, and U.S. territories, as well as internationally in countries including Canada, Japan, Mexico, and parts of Europe. The movement continues to stage monthly protests including a large planned event for October 18, 2025, emphasizing broad, peaceful mass engagement against perceived creeping authoritarianism. The No Kings protests highlight widespread public concern regarding the erosion of civil rights, aggressive policies, and political corruption attributed to the Trump administration.
