Welcome to The Encyclopedia of Arda

The Encyclopedia of Arda is a personal project - a tribute to and a celebration of the works of J.R.R. Tolkien. The site is evolving into an illustrated hypertext encyclopedia of Tolkien's realms and peoples. It already contains about four thousand entries, and we're constantly adding new entries and expanding existing ones.

Inside the encyclopedia

The Encyclopedia of Arda contains thousands of articles covering topics from J.R.R. Tolkien's world, some brief, some lengthy and some containing detailed essays and discussions.

You'll also find a selection of interactive tools, including a chronicle to help you explore Tolkien's fictional history, and calendar to translate dates and events, a lexicon of names, a glossary of old and rare words, and much more.

Context and approach

The content of the Encyclopedia is written in the same context as Tolkien himself used; he presented himself simply as a translator, rather than originator of the tales. Hence, we try to describe his world from a 'historical' rather than a literary perspective, though sometimes it's useful to explore ideas in their wider context. Where relevant, therefore, you'll also find a few references to Tolkien's life or opinions, or to real historical or mythological parallels to events in his universe.

About the name Arda

Arda was the name given by the Elves to their world and all it contained, and so 'Encyclopedia of Arda' seemed a peculiarly apt title for this project.

Special thanks

Thanks to all those who've e-mailed us over the years with their suggestions, corrections, ideas and just general support.

But the real Special Thanks, though, belong to the memory of J.R.R. Tolkien for his extraordinary and unparalleled creation.

A leader of the Northmen

A descendant of Forthwini of the Northmen, Frumgar became the Lord of the Éothéod at a time when they were dwelling in the Vales of Anduin near the southern parts of Mirkwood. At that time the Vales were becoming populous with peoples of Men, and the shadow of nearby Dol Guldur was spreading from the Forest. When word came to Frumgar of the fall of Angmar, therefore, he resolved to lead his people up the Great River to seek freer lands in the North.

When they reached the lands around the sources of Anduin, they did not find them deserted: survivors of Angmar were still dwelling there, having fled eastward from the Misty Mountains after the Witch-king's departure. Frumgar's people defeated them, and settled the lands around the rivers Langwell and Greylin, forming a nation that would survive for more than five hundred years.
