The Silmarillion was the first major Middle-earth legendarium book published after J.R.R. Tolkien’s death.
Tolkien died in 1973, and his son Christopher Tolkien edited The Silmarillion for publication in 1977. The book brings together creation myths, the history of the First Age, and accounts of the Elves, Men, Valar, and major conflicts against Morgoth. It is not a conventional single novel; it is a collection of interconnected mythic narratives and historical texts.
The title refers especially to the Silmarils, three jewels made by the Elf Fëanor. Their theft by Morgoth drives much of the book’s central story and leads to centuries of war and tragedy.
Readers sometimes assume Tolkien completed a final manuscript in the same polished form as The Lord of the Rings. In reality, Christopher assembled and edited material from many drafts, notes, and versions. Later publications, including Unfinished Tales and The History of Middle-earth, reveal more of the creative process behind the mythology.
