Cultural Revolution: Vast majority of all works of art or literature destroyed. I believe there were other occasions in Chinese History where literature was burnt but I cant recall them offhand.
Perhaps one of the most tragic things ever.... centuries of artifacts, history, and culture destroyed from one of the oldest civilizations, no less. Really irritating to think about.
