Although all Men in Tolkien's legendarium are related to one another, there are many different groups with different cultures. Those on the side of the hobbits in The Lord of the Rings are the Dúnedain, the men who fought on the side of the Elves in the First Age against Morgoth in Beleriand, from whom other friendly groups, the Rangers including Aragorn, and the men of Gondor are descended; and their allies the Rohirrim.
