A desert region commonly called South Gondor, that lay beyond the River Poros from Gondor itself, and extended southwards for some two hundred miles, until its southern border was defined by the River Harnen. The Harad Road ran through this land, connecting South Ithilien to the Harad beyond the Harnen.
Throughout the first half of the Third Age, Harondor was under the control of the Kings of Gondor, but that changed at the time of civil war known as the Kin-strife. At that time, Castamir the Usurper took the rightful throne from KingEldacar, but was ultimately overcome and slain. Castamir's sons were besieged at Pelargir for a time, but escaped by sea to settle in Umbar, where they founded a haven for the enemies of Gondor. From that haven far to the south, the forces of the Corsairs began to ravage Harondor, and it became a debatable land between Gondor and Umbar.
