Censorship in Nazi Germany was extreme and strictly enforced by the governing Nazi Party. The government attempted to tightly control information available to their citizens. Almost all Modernist art was considered degenerate art by the Nazi regime. Amongst those who were suppressed both during the Nazi book burnings and the attempt to destroy modernist fine art in the "degenerate" art exhibition were:Ernest Hemingway,
John Dos Passos,
Philosophers, and sociologists were suppressed by the Nazi Germany:Albert Einstein,
Politicians suppressed by the Nazi Germany:Konrad Adenauer,
To avoid censorship of books they were often given an innocent looking cover, so called Tarnschriften.
