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.

Dagor Bragollach

The Battle of Sudden Flame

For some four centuries, the forces of the Noldor had besieged Morgoth in his northern fortress of Angband, holding the northern mountain fences of Beleriand and their passes against his forces. In I 455 Morgoth broke the Siege of Angband in the battle that came to be known as the Dagor Bragollach, the Battle of Sudden Flame.

The Battle began one night in winter, when Morgoth sent out rivers of flame from Angband that consumed the wide plains of Ard-galen. Then came his armies of Balrogs and Orcs, led by Glaurung the dragon. They forced the highlands of Dorthonion, and took the fortresses of Angrod and Aegnor who dwelt there. Maglor's Gap was also taken, giving Morgoth an entry into Beleriand itself.
