Brightwater: "There's nothing on the southern continent?"
Marcross: "Nothing but a civil war. Been going on for the past ten years."
Korlo Brightwater and Saberan Marcross[src]

The South Cont's civil war was a civil war taking place on the southern continent of the planet Ranklinge. The northern continent, which was the location of the most important cities of the planet, was spared from the conflict.

After two years of war, the Galactic Empire sent a couple of diplomats in 8 BBY to mediate the conflict. They didn't managed to solve the war and all Imperial forces eventually left the planet. The civil war was not ended in the months following the Battle of Yavin.
