The Southern confederacy was a charade alliance of Petty-Kings and Chieftains of the Haradrim, who were de facto puppet-rulers installed by the Kingdom of Gondor in its golden age to pacify the Haradwaith. The Southern Confederacy was first founded in TA 1050 and TA 1634 and was briefly renewed from T.A. 1810 to T.A. 1944.
The Kings of the Southern Confederacy were the Autarb or Taskral of Harûzan, the "Taryb" of Sirayn. These chieftains were selected for lack of ties to the Dark Lords and often held their residences and those of their families in Gondor proper, thus becoming largely Gondorian in nature.
