ACT UP was formed in March of 1987 at the Lesbian and Gay Community Services Center in New York. Three weeks later they held their first protest on Wall Street. Today there are over 70 chapters worldwide and thousands of members. ACT UP uses non-violent direct action and often civil disobedience to bring attention to the AIDS crisis.
They are well know for their provocative demonstrations and their famous slogan/logo: "Silence = Death" with an uninverted pink triangle.
