The 1950s "Red Scare" marks one of the stormiest periods in U.S. Supreme Court history. Robert M. Lichtman provides the definitive history of the high court's decisions in every one of the "Communist" cases it decided, placing each within the context of the time and revealing the broad range and impact of McCarthy-era repression. Making extensive use of the justices' papers, Lichtman examines the dynamics of the Court's changes in direction, from the Vinson Court's rubber-stamping of government action against subversives to the Warren Court's more liberal rulings and the subsequent retreat led by Felix Frankfurter. Lichtman's account details the Court's surprising vulnerability to popular and political attack and reveals the behind-the-scenes relationships and rivalries among justices. At the same time, he recounts in devastating detail the injuries inflicted by McCarthyism on individuals and the nation.
