"The Hyborian Age" is an essay by Robert E. Howard pertaining to the Hyborian Age, the fictional setting of his stories about Conan the Cimmerian. The essay sets out in detail the major events of Howard's pseudohistorical prehistory, both period before and after the time of the Conan stories. In describing the cataclysmic end of the Thurian Age, the period described in his Kull stories, Howard links both sequences of stories into one shared universe. The names he gives his various nations and peoples of the age borrow liberally from actual history and myth. The essay also sets out the racial and geographical heritage of these fictional entities, making them progenitors of modern nations. For example, Howard makes the Gaels descendants of his own Cimmerians.
