Alderaan Civil War

The Alderaan Civil War was a conflict on the planet Alderaan during the Cold War.

Prelude
After Alderaan was invaded by the Sith Empire during the Great Galactic War, which was eventually repelled and obliterated by the Galactic Republic, the leaders, for the first time in history, became a voice for aggressive military action in the Senate. After the Treaty of Coruscant was signed, Senator Gaul Panteer, the crown prince of Alderaan, marched out of the Senate chamber in protest. Alderaan seceded from the Republic, and became an independent system. The decision of the crown prince was met with mixed reaction by the Alderaanian people; though many were supportive, others were outraged.

Despite the controversy, the Alderaan security forces managed to keep order until the crown prince was assassinated; just days later, the Queen died heirless. The Alderaanian Parliament was deadlocked on which of the noble houses should inherit the throne. Civil war erupted when House Thul, backed by the Sith Empire, decided to settle the matter by force.

The conflict
The civil war ceased to be internal when a forgotten house returned with Imperial backing and the Republic started funneling support to the House Organa. Even though neither superpower officially had any troops on the ground, Alderaan became a site of conflict between them in the post-war galaxy.

Bouris Ulgo protested House Thul's return, stating that they're just puppets for an Imperial invasion, and attempted to rally the other houses to expelling Thul once more. But as the houses were too fractured to realize it, Ulgo decided to take action by usurping the throne from the Panteers. This only caused all the houses, excluding House Rist, to turn against him as well.

There were ongoing peace talks between the Houses at a secret location, but the Jedi envoy, Sidonie Garen of House Organa was infected with a madness plague, and she nearly escalated the war further until Yuon Par's Padawan, the future Barsen'thor, as envoy to Teral stopped her. The Barsen'thor then negotiated the summit to agree to a truce and to reconvene at a later date. The Hero of Tython also helped to preserve talks between houses Thul and Organa by saving the life of the Head of House Thul from the Death Mark Superweapon, utilized by Lord Nefarid to escalate the conflict.

Eventually, Bouris Ulgo was captured by an elite strike team. It was later discovered that Houses Ulgo and Rist were behind Gaul Panteer's death.

Behind the scenes
Alderaan Civil War is also the name of a Warzone in the game Star Wars: The Old Republic. Set on Alderaan during the civil war period, Republic and Imperial teams fight to control heavy laser cannons in a strategic battlezone, hoping to use those cannons to destroy the opposing faction's troop transport.
