This thesis examines the control of books during the Nazi regime in Germany. In the Weimar Republic, although there were limitations, freedom of expression and publication were guaranteed by Article 118 of the Weimar Constitution of 1919. However, there were legal mechanisms in place to regulate publishing, which allowed for the suppression of politically undesirable texts. After the Nazis seized power in 1933, they intensified their control over literature and culture. Through decrees, the police were given the authority to ban books they deemed a threat to public safety or the interests of the state. Book burning became a symbol of an attempt to eradicate ideas and silence political rivals. In the second part of the thesis, organizations such as the Ministry of Public Enlightenment and Propaganda, the National Chamber of Literature, the Gestapo, and the SD are explored as powerful mechanisms of control and repression. Joseph Goebbels, the leader of the Ministry of Public Enlightenment and Propaganda, played a crucial role in shaping German culture and literature in line with Nazi ideologies. The third part analyzes various forms of censorship, such as preventive, suspensive, and self-censorship. Examples illustrate how censorship and book burning in the past posed a serious threat to freedom of expression, democratic society, and cultural diversity. In conclusion, the importance of protecting freedom of expression and curbing censorship is emphasized in building a democratic and inclusive society that fosters open dialogue and respects different perspectives. Learning from past examples encourages us to promote freedom of speech and preserve pluralism of thought as fundamental values in contemporary society.
