During the early years of the Cold War, the anti-communist witch hunt that we now call McCarthyism swept through American society. As we will discover, McCarthyism was much more than the career of the blustering senator from Wisconsin who gave it a name. It was the most widespread and longest-lasting episode of political repression in American history. Dozens of men and women went to prison, thousands lost their jobs, and untold numbers of others saw what happened to those people and refrained from expressing controversial or unpopular ideas.
