Orcs are vile beasts, corrupted Men, Elves and Dwarves that have been defiled by the powers of Melkor. They are the basis of most evil armies in Middle-earth (especially in Mordor and the Misty Mountains). When left to their own devices, orcs would usually split into separate tribes and fight against each other while raiding other villages in the process. They were undisciplined and badly armed, able to be fought off by most soldiers of Men, Elves or Dwarves. It took a strong leader (for example, Morgoth, Sauron, Azog or Bolg) to unite the orc tribes and let them show their full strength in war against the Free Peoples. However, they were still classed as inferior compared to the Easterlings and Haradrim.
