Fingon, son of Fingolfin, was one of the most valiant of all the High-Elves in Middle-earth.
At the beginning of the First Age, Fingon went with his father and people from Aman to Middle-earth; here, Fingon attempted to repair the breach between the House of Fëanor and the rest of the Noldor. He achieved this when, aided by Thorondor, he freed Maedhros on the face of Thangorodrim. He later settled in Dor-lómin and fought in the Wars of Beleriand; in FA 260 he defeated Glaurung.
When his father was slain in the Dagor Bragollach, Fingon became the High King of the Noldor; but just fifteen years into his reign, he was slain by Gothmog, the Lord of the Balrogs, in the Nirnaeth Arnoediad. He was succeeded by his younger brother, Turgon, King of Gondolin.
Though he did not wed, in the published Silmarillion, Fingon is the father of Gil-galad.
