The House Un-American Activities Committee was formed and Alger Hiss was prosecuted and convicted as a Soviet spy.These were the two events which contributed to Joseph McCarthy's rise to power during the early 1950s. Although the House Un-American Activities Committee was taking care of the same issues they thought were prevalent as McCarthy, they were not actually linked and never worked together. Since Alger Hiss was already a known personality, his conviction created a sort of hysteria to find suspected communists, which aided McCarthy's cause.
