who started the red scare in the united states in the 1950s
Red Scare The second Red Scare occurred after World War II (1939–45), and was popularly known as "McCarthyism" after its most famous supporter, Senator Joseph McCarthy. McCarthyism coincided with increased popular fear of communist espionage consequent to a Soviet Eastern Europe, the Berlin Blockade (1948–49), the Chinese Civil War, the confessions of spying for the Soviet Union given by several high-ranking U.S. government officials, and the Korean War.
Origins of the Cold War The Origins of the Cold War involved the breakdown of relations between the Soviet Union versus the United States, Great Britain and their allies in the years 1945–1949. From the American-British perspective, first came diplomatic confrontations stretching back decades, followed by the issue of political boundaries in Central Europe and political non-democratic control of the East by the Soviet Army. Then came economic issues (especially the Marshall Plan) and then the first major military confrontation, with a threat of a hot war, in the Berlin Blockade of 1948–1949. By 1949, the lines were sharply drawn and the Cold War was largely in place in Europe.[1] Outside Europe, the starting points vary in the late 1940s or early 1950s.[2]
