Third Age

The Third Age was a period of time in Middle-Earth lasting for about 3021 years. It was characterized by Isildur loosing the One Ring and his descendants loosing their throne, Sauron re-rising to power after his defeat at the end of the Second Age, the rediscovery of the Ring, the Fellowship of the Ring, the War of the Ring, and, finally, the destruction of the Ring and Sauron. The Third Age officially ended two years afterward, with the departure of Gandalf, Elrond, Galadriel, and Bilbo and Frodo Baggins to Valinor, but some people say it ended the day of Sauron's defeat.

Events of the Third Age are chronicled in The Hobbit and The Lord of the Rings.
