On March 11, 2026, the No Kings Coalition publicly announced March 28 as the date for its third nationwide day of protest, with organizers targeting close to 9 million participants and describing it as potentially the largest single day of protest in American history.
Boston's event — announced the same day by a coalition including the ACLU of Massachusetts, Indivisible Mass Coalition, and Mass 50501 — was set for Boston Common from 1 to 4 p.m. The flagship event nationally was planned for Minneapolis and St. Paul, chosen for their centrality to the ICE enforcement killings that had catalyzed the movement. More than 1,000 locally organized events were already confirmed across the country.
The No Kings movement had grown substantially since its first mobilization. Previous rounds had drawn between 2 million and 6.5 million participants nationally. For the March 28 event, organizers described unprecedented preparation: weeks-long safety and security buildups, formal de-escalation trainings, coordination with legal observers, volunteer marshal training through Indivisible, and a nationwide "Eyes on ICE" monitoring program whose first virtual training session drew more than 200,000 viewers.
The movement was triggered initially by ICE enforcement killings — including those of Renee Good, Keith Porter Jr., and Alex Pretti — and the administration's aggressive immigration operations. The March 28 protests were being organized by a coalition including Indivisible, 50501, and the AFL-CIO, representing an unusual convergence of grassroots civic resistance groups and organized labor.
