Gil-Galad was one of the High
Kings of the
Noldor. The only son of High King
Fingon, Gil-galad was born late in the
First Age, and was still a child at the time of the
Dagor Bragollach; his father sent him to
Círdan at the Havens for safekeeping when
Morgoth broke the Siege of
Angband in that battle.
Fingon was lost in the
Nirnaeth Arnoediad, but the crown passed to Gil-galad's uncle
Turgon in
Gondolin, rather than Gil-galad himself (presumably because of his youth at that time). When Gondolin was lost, Gil-galad received the Kingship of the Noldor; he dwelt with the Exiles of the
city at the Mouths of Sirion during the remainder of the First Age.
After the destruction of
Beleriand during the
War of Wrath, Gil-galad founded a kingdom in
Lindon in the far northwest of
Middle-earth, between the
Blue Mountains and the Great Sea. There he and his people prospered, until
Sauron returned; he came first to Lindon in the form of
Annatar, the Lord of Gifts, but Gil-galad and
Elrond rejected him. Soon after,
the One Ring was forged, and there was war in Middle-earth between the
Elves and Sauron.
After the Downfall of
Númenor,
Elendil and his sons came to Middle-earth and formed an alliance with Gil-galad, the Last Alliance of Elves and
Men. They marched on
Mordor and besieged Sauron's
Dark Tower. Sauron was defeated, but Gil-galad met his death in that war.
