Step-by-step explanation:
Rallies and Marches in U.S. History
In 1982, nearly 1 million people participated in an anti-nuclear march in New York City, which was one of the many significant demonstrations that took place in the United States during the 20th and 21st centuries. Notable historical rallies include the 1963 March on Washington for Jobs and Freedom, where Dr. Martin Luther King Jr. delivered his iconic "I Have a Dream" speech to over 200,000 people, and the first national March on Washington for Lesbian and Gay Rights in 1979. These marches and rallies are crucial elements of the social and political landscape, often representing the collective voice seeking change and the advancement of human rights.
While the 1982 anti-nuclear rally was immense, it did not surpass the number of participants in the summer 2020 Black Lives Matter protests. Across several decades, movements like the LGBTQ pride parades and rallies, anti-war protests, women's suffrage marches, and immigrant solidarity rallies, have brought together millions of participants, each with the aim of pushing forward critical social issues and advocating for their rights.
