The Seattle General Strike earned headlines across the nation, and across oceans. In an extraordinary act of solidarity, members of more than one hundred unions had voted to stop work in support of shipyard workers who had already been on strike for two weeks. This talk explores the event and its legacies. The General Strike led off the great strike wave of 1919 and has served later generations of labor radicals as an inspiration. It also anchors the political reputation of the Pacific Northwest as a region friendly to radicalism.
