The Iron Hills is one of the seven kingdoms of the race of Dwarves and was founded by Grór son of Dáin I after the Dwarves were exiled from the Grey Mountains to the west (And south, see Thrór and Erebor) because of attacks by Cold-Drakes seeking the vast wealth of the mountains, which resulted in the death of the king Dáin I. The Iron Hills were colonized at around the time of 2500 of the Third Age.
