The Chicano Moratorium, formally known as the National Chicano Moratorium Committee, was a movement of Chicano anti-war activists that built a broad-based coalition of Mexican-American groups to organize opposition to the Vietnam War. Led by activists from local colleges and members of the "Brown Berets", a group with roots in the high school student movement that staged walkouts in 1968, the coalition peaked with an August 29, 1970 march in East Los Angeles that drew 30,000 demonstrators.
The Chicano Moratorium was a movement of Chicano activists that organized anti-Vietnam War demonstrations and activities in Mexican American communities throughout the Southwest and elsewhere from November 1969 through August 1971. "Our struggle is not in Vietnam but in the movement for social justice at home" was a key slogan of the movement. It was coordinated by the National Chicano Moratorium Committee (NCMC) and led largely by activists from the Chicano student movement and the Brown Beret organization.
The committee organized its first demonstration on December 20, 1969, in East Los Angeles, with over 1,000 participants. The groups won the early support of the Denver-based Crusade for Justice, led by Rodolfo Gonzales, also known as Corky Gonzales. A conference of anti-war and anti-draft Chicano and Latino activists from communities in the Southwest and the city of Chicago was held at the Crusade headquarters in early December 1969. They began developing plans for nationwide mobilizations to be presented to a national Chicano youth conference planned for late March 1970. On February 28, 1970, a second Chicano Moratorium demonstration was held again in East Los Angeles, with more than 3,000 demonstrators from throughout California participating, despite a driving rain. Las Adelitas de Aztlán marched in the February march, which NCMC organizer Rosalío Muñoz sees as the first time a Chicana organization participated in its own right in a Chicano demonstration. A Chicano program on the local public television station produced a documentary of that march, used nationally by the committee to popularize its efforts. At the March Chicano Youth Conference, held in Denver, Rosalío Muñoz, the co-chair for the Los Angeles Chicano Moratorium, moved to hold a National Chicano Moratorium against the war on August 29, 1970. Local moratoriums were planned for cities throughout the Southwest and beyond, to build up for the national event on August 29.
