During which years did the Second Red Scare predominantly occur?

The Second Red Scare primarily took place from 1947 to 1956, marked by a heightened fear of communism that permeated American society during the early Cold War. This period was characterized by significant events such as the establishment of loyalty review boards, the conduct of hearings by Senator Joseph McCarthy, and widespread accusations against individuals in government, entertainment, and other sectors, leading to the blacklisting of many who were suspected of communist affiliations. The climate of fear and suspicion during these years largely stemmed from geopolitical tensions, particularly the emergence of the Soviet Union as a superpower and the beginning of the Korean War in 1950. The culmination of this scare, effectively, saw its decline after the Army-McCarthy hearings in 1954 and the political fallout that followed. The time frame of 1947 to 1956 accurately reflects the intensity of anti-communist sentiment and related actions, which defined this era in American history.
