1054 – A supernova was seen by Chinese, Arab, and possibly Amerindian observers near the star Zeta Tauri. For several months it remained bright enough to be seen during the day. Its remnants form the Crab Nebula.
1848 – The Communist Manifesto published.
1971 – Death of August Derleth, American writer and anthologist. Though best remembered as the first publisher of the writings of H. P. Lovecraft, and for his own contributions to the so-called Cthulhu Mythos genre of horror, as well as his founding of the publisher Arkham House (which did much to bring supernatural fiction into print in hardcover in the US that had only been readily available in the UK), Derleth was also a leading American regional writer of his day, as well as prolific in several other genres, including historical fiction, poetry, detective fiction, science fiction and biography.
