In J.R.R. Tolkien’s invented history, Fingolfin became the first High King of the Noldor in Middle-earth.
Fingolfin is the second son of Finwë, the first king of the Noldor, and the half-brother of Fëanor. After the Noldor leave Valinor and cross into Middle-earth, Fingolfin leads many of them across the dangerous Helcaraxë, the Grinding Ice. He reaches Middle-earth after Fëanor’s death and assumes the kingship of the Noldor there.
Fingolfin rules from Hithlum and becomes one of the principal Elven leaders in the wars against Morgoth. His most famous deed is the single combat in which he challenges Morgoth at the gates of Angband. Although he is ultimately defeated, the duel demonstrates extraordinary courage and inflicts a lasting wound on Morgoth.
Fingolfin is often confused with Fëanor, who was the first High King of the Noldor in Valinor and initiated the rebellion. Gil-galad becomes a later High King, while Finwë is the earlier king before the exile.
