This study analyzes the leadership qualities of Joseph McCarthy and the rhetorical qualities of agitative and control forces in a specific social movement. The methods used are founded upon various theories outlined by sociologists, historians, and rhetoricians. This investigation is organized around the climate of the times, McCarthy's leadership development, agitative strategies, control group responses, and support and opposition groups. It was found that the movement's success was probably due to McCarthy's position of attack and offense and to the control group's failure to neither strongly confront McCarthy nor to maintain its preparedness and superiority. It is theorized that had the control group engaged earlier in strategies other than adjustment and avoidance, the movement might have been halted sooner.
