Aragorn becomes king of Gondor at the end of J.R.R. Tolkien’s The Lord of the Rings.
Aragorn is introduced as the ranger Strider, but he is secretly the heir of Isildur and the rightful claimant to the thrones of Gondor and Arnor. During the War of the Ring, he helps lead the Free Peoples against Sauron and proves his authority through courage, lineage and leadership.
After Sauron’s defeat, Aragorn is crowned King Elessar. He marries Arwen, the daughter of Elrond, and begins the reunification of the northern and southern kingdoms of the Dúnedain. His reign represents the restoration of legitimate human kingship after generations of decline.
Boromir and Faramir are important men of Gondor, but neither becomes its king. Denethor is the ruling steward during much of the story. Aragorn’s royal identity is one of the novel’s central revelations and is foreshadowed by his sword and ancestry.
