THE BEGINNING
The Fourth Age begins with the passing of the elves into the uttermost west, to Valinor; the Undying Lands. The ring bearers and other magical beings went as well. Aragorn, the 34th king of Gondor, the 26th king of Arnor and the 1st high king of the Reunited Kingdom was rebuilding Middle-Earth in days of peace. The dwarves have reclaimed the Mines of Moria and Gimli is the new Lord of Moria. Gimli and his kin helped rebuild Minas Tirith after the War of the Ring. They made a new gate for Minas Tirith, a gate made of Mithril. The dwarves also repaired Helms Deep. Faramir was now the Prince of Ithilien. Eomer is now the King of Rohan.
