Books like hard to be a god

Hard to Be a God (Russian: Трудно быть богом, romanized: Trudno byt' bogom) is a 1964 science fiction novel by Soviet writers Arkady and Boris Strugatsky, set in the Noon Universe.

The novel follows Anton, an undercover operative from the future planet Earth, in his mission on an alien planet that is populated by human beings whose society has not advanced beyond the Middle Ages. The novel's core idea is that human progress throughout the centuries is often cruel and bloody, and that religion and blind faith can be effective tools of oppression, working to destroy the emerging scientific disciplines and enlightenment. The title 'Hard to Be a God' refers to Anton's (known as his alias Don Rumata throughout the book) perception of his precarious role as an observer on the planet, for while he has far more advanced knowledge than the people around him, he is forbidden to assist too actively as his assistance would interfere with the natural progress of history. The book pays a lot of attention to the internal world of the main character, showing his own evolution from an emotionally uninvolved 'observer' to the person who rejects the blind belief in theory when confronted with the cruelty of real events.
