Tolkien conceived of The Lord of the Rings as a single volume comprising six sections he called "books" and extensive appendices. The original publisher made the decision to split the work into three parts, publishing the fifth and sixth books and the appendices under the title The Return of the King, in reference to Aragorn's assumption of the throne. Tolkien indicated he would have preferred The War of the Ring as a title, as it gave away less of the story.
