Dominion of Men
From Tolkien Gateway
The Dominion of Men is a period of time that officially began with the advent of the Fourth Age and Aragorn's ascent to the Throne of Gondor, though more strictly speaking it took place much earlier, at the end of the First Age. The phrase "Dominion of Men" refers to the fact that Men inherited the mastery of Middle-earth from the Elves, most of whom then left Middle-earth and sailed to the West.
