McCarthyism is the practice of making accusations of subversion or treason, especially when related to communism. The term refers to U.S. senator Joseph McCarthy (R-Wisconsin) and has its origins in the period in the United States known as the Second Red Scare, lasting from the late 1940s through the 1950s.
