The Lord of the Rings was written by J.R.R. Tolkien in the United Kingdom between 1937 and 1949. Since Tolkien, a Roman Catholic, wanted to create a unique English mythology, he turned to what he knew, taught, and frequently studied: Anglo-Saxon (and other past language) and fairy-stories. One work that included both of these interests was Beowulf, the famous Old English saga and source that Tolkien frequently drew upon to form his mythology, and which he wrote his own translation of. Tolkien also recalled several features of the United Kingdom while writing, most notably the quaint, northern English countryside and town he grew up in, Sarehole, and the Welsh language, upon which was based Sindarin, the most familiar Elvish variant.
