Orcs

Orcs were the primary foot soldiers of the Dark Lords' armies and sometimes the weakest (but most numerous) of their servants. They were created by the first Dark Lord, Morgoth, before the First Age and served him and later his successor in their quest to dominate Middle-earth. Before Oromë first found the Elves at Cuiviénen, Melkor kidnapped some of them and cruelly tortured them, twisting them into the first Orcs.
