Battle of the Pelennor Fields
Aragorn led the Fellowship of the Ring following the loss of Gandalf in the Mines of Moria. When the Fellowship was broken, he tracked the hobbits Meriadoc Brandybuck and Peregrin Took with the help of Legolas the elf and Gimli the dwarf to Fangorn Forest. He then fought in the battle at Helm's Deep and the Battle of the Pelennor Fields. After defeating Sauron's forces in Gondor, he led an army of Gondor and Rohan against the Black Gate of Mordor, distracting Sauron's attention and enabling Frodo Baggins and Samwise Gamgee to destroy the One Ring. Aragorn was acclaimed as King by the people of Gondor, and crowned King of both Gondor and Arnor. He then married Arwen and ruled for 122 years.
