Students for a Democratic Society
In the spring of 1968, National SDS activists led an effort on the campuses called "Ten Days of Resistance" and local chapters held rallies, marches, sit-ins and teach-ins, ending in a one-day strike on April 26. About a million students stayed away from classes that day, the largest ever student strike in the history of the United States. It was mostly ignored by the New York City-based national media, which was more focused on the student shutdown of Columbia University in NYC, led by an inter-racial alliance of Columbia SDS chapter activists and Student Afro Society activists. Because of the Columbia Student Revolt, "SDS" became a household name in the United States for a few years; and membership in SDS chapters around the United States grew greatly during the 1968-69 school year.
