Fahrenheit 451 is a dystopian novel written by Ray Bradbury and published in 1953 during the height of the Cold War. The book is set in a future society where books are banned and "firemen" burn any that are found. The novel takes its title from the temperature at which paper burns.

Bradbury was inspired to write Fahrenheit 451 during the McCarthy era, a time in the 1950s when the United States government was actively seeking out and punishing anyone with suspected communist ties. Bradbury himself was concerned about censorship and the suppression of free speech, and he believed that books were important for the preservation of knowledge and for the development of critical thinking. The novel has since become a classic in the dystopian genre and serves as a warning against the dangers of censorship, conformity, and the suppression of individual thought and expression.
