Which Tolkien novel follows The Hobbit and features the One Ring’s destruction?

The Tolkien novel that follows The Hobbit and features the One Ring’s destruction is The Lord of the Rings.

Tolkien wrote The Lord of the Rings between 1937 and 1949, although publication was delayed by production and paper shortages. George Allen & Unwin issued it in three volumes from 1954 to 1955: The Fellowship of the Ring, The Two Towers, and The Return of the King.

The story follows Frodo Baggins as he carries the One Ring toward Mount Doom, where it can be destroyed. The quest expands into a wider war against Sauron and involves characters including Samwise Gamgee, Aragorn, Gandalf, Legolas, and Gimli.

It is sometimes called a trilogy because of its three-volume publication, but Tolkien regarded it as one novel. The three titles are volume titles, not three independent novels written as a conventional trilogy.
