Men

Men are the second race after the Elves, similar to them but mortal. They live 60-100 years. Although in ancient times their span of years was much greater, they were more shortlived than all other races.

However the compensation of mankind was its vast numbers and destiny to rule Middle-earth.

History
In the First Age they allied with the Elves in the War of the Silmarils. Hurin and Turin as well as Beren made great deeds. Other men fell under the influence of Melkor and fought alongside monsters against other Men, Elves and Dwarves.

Mankind suffered much in the battles and in the Second Age they were given Numenor by the Valar as a reward. The Numenoreans or Dunedain had an extremely long lifespan. In the end the Faithful led by Elendil made the Last Alliance with the Elves to fight Sauron.

Human nations in Middle-earth were Arnor, Rohan, Dunland, Gondor, Dunharrow with the fine cities, Harad in the south and Rhun in the east.

Those in the far east and south are allied with Sauron. Those were Balchoths, the Wainriders, the Easterlings, and the Haradrim or Southrons.
