Who is Aragorn?
Aragorn II, son of Arathorn II and Gilraen, also known as Strider and Elessar, was the 16th and last Chieftain of the Dúnedain of the North; later crowned King Elessar Telcontar (March 1, 2931 of the Third Age - Fourth Age 120), the 26th King of Arnor, 35th King of Gondor, and first High King of Gondor and Arnor since the short reign of Isildur. Aragorn was a skilled ranger and warrior. As the heir of Isildur, he carried the shards of Narsil, which were reforged and renamed Andúril ('Flame of the West') during the War of the Ring.
Lineage and Heritage
Aragorn was a descendant of Elros Tar-Minyatur through the line of the Lords of Andúnië to Elendil, High King of Arnor and Gondor. Like all of the kings before him, he was Elrond's kin through the House of Elros. His ancestor Arvedui was wedded to Fíriel, descended from Anárion, who bore their son Aranarth, making Aragorn the last descendant of both Isildur and Anárion.
"He was Aragorn son of Arathorn, the nine and thirtieth heir in the right line from isildur, and yet more like elendil than any before him."
Early Life and Secret Identity
He was born in 2931, and when he was only two years old, his father Arathorn was killed while pursuing Orcs. Aragorn was afterwards fostered in Rivendell by Elrond. At the request of his mother, his lineage was kept secret, as she feared he would be killed like his father and grandfather if his true identity as the descendant of Elendil and Heir of Isildur became known. Aragorn was renamed "Estel" and was not told about his heritage until 2951.
Revelation of True Identity
Elrond revealed to "Estel" his true name and ancestry when he was twenty, giving him the Ring of Barahir and the Shards of Narsil, but withholding the Sceptre of Annúminas from Aragorn until he "came of the right" to possess the item. It was also around this time that Aragorn met and fell in love with Arwen, Elrond's daughter, newly returned from her mother's homeland of Lothlórien where she had been visiting her grandmother Galadriel.
Leadership of the Dúnedain
Aragorn thereafter assumed his proper role as the sixteenth Chieftain of the Dúnedain and left the comforts of Rivendell for the wild, where he lived with the remainder of his people, the Rangers of the North, whose kingdom had been destroyed through division and the Angmar Wars centuries before.
