Beginning in September 1948, the Soviet Union sponsored a series of "peace" conferences that denounced the Truman administration. The first held in the West took place at New York's Waldorf-Astoria Hotel in March 1949, where 800 writers and artists promoted peace with Stalin and accused the US of war-mongering, promoting harassment from the Americans for Intellectual Freedom. The Office of Policy Coordination(OPC), the CIA's new covert action arm, viewed these events and began planning how to counteract.
After a US-backed counter-conference in Paris in April 1949, American officials concluded that a more effective and credible anti-communist response was needed. After a planning meeting in Frankfurt, the decision was made to host an international conference for anti-Communism in Berlin the next year.
The CIA knew that if the US government openly sponsored the conference, it would lose credibility. The Truman administration officers also did not want to sponsor the former Communists. In late 1949, Michael Josselson proposed covertly funding the congress. CIA members were told to stay away from the congress, as to not cause suspicion or criticism.
The CCF convened in Berlin's Titania Palace on June 26, 1950. It was proof that even though people had differing beliefs, they could be civil and share those beliefs, as they were all against Communism. OPC officers began campaigning to have permanent covert backing for the CCF, which was approved.
Through the CCF, the CIA published political/literary journals, hosted dozens of conferences for the most eminent Western thinkers and helped intellectuals behind the Iron Curtain.
