Rohan (Middle-earth)

Rohan is a kingdom of horsemen, the Rohirrim, in J. R. R. Tolkien's fantasy setting of Middle-earth. It is mainly a grassland, and provides its ally Gondor with cavalry. The Rohirrim call their land the Mark or the Riddermark, the name recalling that of the Kingdom of Mercia, the region of Western England where Tolkien lived.
