Not all Men were on the side of good; the Men who lived in the east and south were under Sauron's dominion. They included the Haradrim or Southrons and the Black Númenóreans (and later the Corsairs of Umbar) who pledged their allegiance to Mordor, and many different Easterling peoples, such as the Balchoth, the Wainriders, and the Men of Khand, who attacked Gondor and Rohan on numerous occasions. The Men of Dunland served as agents to the traitorous wizard Saruman. In the First Age, some Easterlings were under Morgoth's dominion.
