Rohan, or the Riddermark (Rohirric), was a great kingdom of Men located in the land once known as Calenardhon, situated in the plains between the Misty Mountains and the White Mountains. The land of Rohan extended from the banks of the River Isen in the west, up to the East wall of Rohan and shores of the River Anduin in the east. The forest of Fangorn lay on its border, and the Elven forest of Lothlórien lay north of the River Limlight.

    The land was known as “Rohan” to the Men of Gondor, and its people the Rohirrim, meaning ‘the Horse-lords’, but the people of Rohan called themselves the Eorlingas, sons of Eorl the Young, first King of Rohan.
