was sauron a elf

*Sauron was not an elf. He was a Maia, which is a type of angelic being in the mythology of J.R.R. Tolkien's "Lord of the Rings" series. The Maiar were created by the Valar, who were even higher up on the hierarchy of angelic beings, and the Maiar were sent to Middle Earth to help the Elves in their fight against the darkness. Sauron was originally a servant of the Vala named Aule, but he later fell under the influence of Morgoth, the Dark Lord, and became his chief lieutenant.*
