Everything you should know before watching Lord of the Rings: War of the Rohirrim
The War of the Rohirrim takes place about 250 years before the events of The Lord of the Rings, during the reign of Helm Hammerhand, king of Rohan. Or, to give you another kind of perspective on things: Helm’s Deep, the massive mountain fortress where the climax of Peter Jackson’s The Two Towers takes place? That’s named after Helm.
