No Kings Day refers to a large-scale, coordinated day of protests held on June 14, 2025, known as the No Kings protests or No Kings Day of Defiance. The protests took place in over 2,100 cities and towns across the United States, as well as in some U.S. territories and international locations. The movement was organized by the 50501 Movement and other allied groups, opposing what they described as authoritarian tendencies and policies of President Donald Trump's second administration. The name "No Kings" symbolizes rejection of authoritarianism, likening Trump’s actions to those of a king or tyrant rather than a democratically-elected leader. The date of the protests coincided with several events: President Trump's 79th birthday, Flag Day in the U.S., and the U.S. Army's 250th Anniversary Parade in Washington, D.C. The protests aimed to counter the military parade, which critics saw as a politicized display mimicking authoritarian regimes. They expressed opposition to the Trump administration's alleged overreach in immigration enforcement, civil rights attacks, and cuts to federal services. Organizers emphasized nonviolent actions and sought to show that the flag and democracy belong to the people, not to a king-like ruler. More than five million people reportedly participated in the events, making it one of the largest single-day protests in recent American history. In summary, No Kings Day was a nationwide and international protest movement against perceived authoritarianism, corruption, and militarization linked to President Trump's policies, held specifically on June 14, 2025, as a symbolic day rejecting "kings" or tyrants in American democracy.
