The people of Rohan were known to outsiders as the flaxen-haired Rohirrim, or Horse-lords, in reference to the close affinity they enjoyed with their horses. Indeed, there were no finer riders among all the tribes of Men. The Eorlingas, they named themselves, as followers of the Line of Eorl, who founded the kingdom of Rohan.
The process of making a film is oft an ever-changing journey. One such changed aspect was the helm worn by the Witch-king during The Return of the King. Whilst this first design was manufactured, and even had scenes shot, it was ultimately decided that its likeness to Sauron's own helm might be perplexing for the audience. Therefore, it was replaced with the Morgul Lord War Mask seen in the final cut of the film.
