The Kingdom of the Forges was one of the independent kingdoms of Westeros until the Massacre at Gornworth. It was founded during the time of the First Men by the Forgers, an ancient group of First Men who were among the first people in Westeros with the knowledge of craftsmanship.

Following the Andal Invasion, the Kingdom of the Forges came to be dominated by Andal culture, though theSmithe dynasty remained in power. The Kingdom of the Forges fell when the last Smithe king, Marthew VII, was killed during the Massacre at Gornworth.
