Outer Rim Coalition

The Outer Rim Coalition was a band of planets located in the Outer Rim Territories, that joined forces and seceded from the Authority in 84 ABY, sparking the Outer Rim Wars

History
Long before the war began, Kaiser Jelahan Mozh met with Darth Plagueis, who was long believed to be dead. Jelahan Mozh offered him a deal, join the Yuuzhan Vong Empire, or be destroyed. Realizing the immense power the Yuuzhan Vong held, Plagueis joined the Empire.

Outer Rim Unrest
In 49 ABY, Kaiser Mozh signed an executive order, increasing taxes on systems in the Outer Rim located on major trade routes. In 50 ABY, the Outer Rim broke out into all-out war, with many systems fighting for domination over the territories, so that systems can afford the increased taxes. By the end of 50 ABY, the Kaiser disbanded the executive order, and peace was restored in the territories, although a hatred for the Authority began to be felt.

Formation of the Coalition and Open Conflict
In 83 ABY, Kaiser Jelahan Mozh again signed an executive order to raise taxes on Outer Rim systems that were located on major trade routes. This time, instead of turning on each other, the territories began to turn on the Authority. Darth Plagueis, under his old alias Hego Damask II, began to rally systems against the Authority. In 84 ABY, the Kaiser placed trade embargoes on all Outer Rim systems that did not pay the taxes, forbidding trade with the rest of the galaxy. This prompted Hego Damask to formally secede his rallied systems from the Authority, forming the Outer Rim Coalition.

Battle of Korda
Soon after the formation of the Coalition, Damask rallied his forces and attacked the Authority outpost world of Korda, beginning the Outer Rim Wars.
