1984 by George Orwell

…

…act of recording his present circumstances constituted extreme disloyalty to the Party because Winston was actually documenting history. Totalitarian rulers throughout history, including Hitler and Pol Pot (the leader of the Khmer Rouge in Cambodia), destroyed books and exterminated journalists and intellectuals because they understood the power of documentation and history. While Orwell clearly shows that history is mutable, he also proves that this type of mutation leads to the death of culture and freedom.
