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 US 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 US antifascism the twenty-first century, showing how generations of writers, organisers, and fighters spoke to each other over time.
