The name means 'People of the South'.

These men were enemies of Gondor who were bent to Sauron's will and fought for him during the War of the Ring. They lived in Harad, in the southern region of Middle-earth.

Oliphaunts, or Mûmakil, were the elephant-like great-war creatures of the Haradrim.

Their banner was the Eye of Sauron and the Snake of the Easterlings in red and black.
