The story began as a sequel to Tolkien's earlier, less complex children's fantasy novel The Hobbit (1937), but eventually developed into a much larger work. It was written in stages between 1937 and 1949, much of it during World War II. Although generally known to readers as a trilogy, Tolkien initially intended it as one volume of a two volume set along with The Silmarillion; however, the publisher decided to omit the second volume and instead released The Lord of the Rings in 1954-55 as three books rather than one, for economic reasons.
It has since been reprinted countless times and translated into many languages, becoming one of the most popular and influential works in 20th-century literature.
