What is book censorship?
Censorship is "the regulation of freedom of expression and other forms of established authority
Let's start with the history of book censorship.
The first book banned in history was Hungarian-born French philosopher and Marxist theorist Politzer's Principes Élémentaires de Philosophie, written in 1936 and published posthumously in 1945.

Banned because of the September 12 coup. Although this was the first written book to be banned in history, book censorship dates back to ancient times.
So what are the real reasons for book censorship?
Book censorship occurs for various reasons, including the desire to protect national security, maintain social order, uphold religious beliefs, and shield individuals from offensive or challenging content.

Moreover, sexual content, offensive language, and violent sentences are some of the reasons why books are banned.
Book censorship is a problem that also has an impact on society. Coups, political issues, political developments, religious beliefs, etc. Books written on topics such as coups, political issues, political developments, religious beliefs, etc. that greatly affected society were also banned.

Books that did not conform to the political and religious position of the time were also often censored.
Another problem of book censorship for the author and society is freedom of expression. If ideas are expressed in books and writings, the banning of these ideas has also restricted freedom of expression.
But at the same time, some of the things written in books can also have a negative impact on society. Whether book censorship is good or not is open to debate and depends on the situation.
