At the Second National March on Washington for Lesbian and Gay Rights, in October 1987, ACT UP New York made their debut on the national stage, as an active and visible presence in both the march, the main rally, and at the civil disobedience at the United States Supreme Court Building the following day. Inspired by this new approach to radical, direct action, other participants in these events returned home to multiple cities and formed local ACT UP chapters in Boston, Chicago, Los Angeles, Rhode Island, San Francisco, Washington, D.C., and other locations, first around the United States, and eventually internationally.
