Since the birth of fascism in the 1920s, well before the global renaissance of "white nationalism," the United States has been home to its own distinct fascist movements, some of which decisively influenced the course of U.S. history. Yet long before "antifa" became a household word in the United States, they were met, time and again, by an equally deep antifascist current. Many on the left are unaware that the United States has a rich antifascist tradition, because it has rarely been discussed as such, nor has it been accessible in one place. This reader reconstructs the history of U.S. antifascism into the twenty-first century, showing how generations of writers, organizers, and fighters spoke to each other over time. Spanning the 1930s to the present, this chronologically-arranged, primary source reader is made up of antifascist writings by Americans and by exiles in the U.S. - some instantly recognizable, others long-forgotten. It also includes a sampling of influential writings from the U.S. fascist, white nationalist, and proto-fascist traditions. Its contents, mostly written by people embedded in antifascist movements, include a number of pieces produced abroad that deeply influenced the U.S. left. The collection thus places U.S. antifascism in a global context.
