Starting of the Fourth Age
There is no information on more than the first few centuries of this age, so it is not known when it ended, if it ever did, although it was probably shorter than 3 millennia.
This age was (presumably) marked by the recovery of the Númenorean kingdoms of Arnor and Gondor, and a flourishing of their subjects, including the Shire and the Hobbits, while the House of Durin retook Moria until the race of Dwarves failed. Eventually that would lead to the final Dominion of Men over Arda, coming together with the total waning of the Elves and other dwindling races, such as the Ents and probably the Dwarves.
For a complete list of recorded events during the Fourth Age, see the Timeline.
Tolkien said that he thought the distance between the end of the Third Age and the 20th century A.D. was about 6000 years, and that in 1958 it should have been around the end of the Fifth Age if the Fourth and Fifth Ages were about the same length as the Second and Third Ages. He said, however, in a letter written in 1958 that he believed the Ages had quickened and that it was about the end of the Sixth Age/beginning of the Seventh.
