The Third Ministerial Conference of the World Trade Organization (WTO) was held in Seattle from November 30 to December 3, 1999. Trade ministers and other officials from the WTO's 135 member nations met in an unsuccessful attempt to plan negotiations to further deregulate free trade. Tens of thousands of activists for many causes gathered to protest what they saw as the WTO's favoring of corporate interests over social and environmental concerns.

This photo shows members of the Infernal Noise Brigade, a Seattle-based marching band that formed in order to "provide entertainment, energy, and support" to the anti-WTO protesters. Over the next seven years, the group performed at several protests in Seattle, as well as large protests across the US and abroad, before disbanding in 2006.

This photo was taken by Ervin Schleufer, a member of the Coeur d’Alene Tribe and retired member of the United Steelworkers of America Local 338. Schleufer was among the striking steelworkers locked out by the Kaiser Corporation in Spokane from 1998 to 2000. In 1999 he traveled the West Coast, with a group calling themselves “road warriors,” to connect with activists, get support for their strike, and raise interest in protesting the WTO conference in Seattle. Schleufer joined thousands of union members from across the country protesting at the WTO conference, and took photos documenting his participation in the street protests.
