Core Worlds Alliance

Established in 432 ABY, the Core Worlds Alliance supplanted the ailing Galactic Alliance as the dominant power in the galaxy. Governed from Coruscant, the Core Worlds Alliance retained the political structure of its predecessor governments—including a Galactic Senate and a Supreme Chancellor—while shifting its economic and social focus to the worlds of the Galactic Core.

In large part a reaction to the secession of thousands of Expiationist worlds from the Galactic Alliance, the founding of the Core Worlds Alliance was largely responsible for the division of the galaxy into the competing spheres of influence of the Core, the Expiationists, and the Hutts. Prior to that time, the government on Coruscant had not recognized the independence of the secessionist systems, considering them to be in rebellion. With the establishment of the Core Worlds Alliance, aid to all but a few worlds in the Outer Rim Territories was entirely ended, leaving these worlds to fend for themselves.

By 435 ABY, the lack of proper infrastructure in the Outer Rim would lead to the collapse of thousands of regional and planetary governments, giving rise to general anarchy. Sensing opportunity, the Core Worlds Alliance would begin a campaign of reconquest that would eventually bring them into conflict with the resurgent Hutt Empire.

In 439 ABY, what would come to be known as the Tripartite War began, pitting the Core Worlds Alliance against a Hutt Empire which controlled a greater extent of territory than at any other time since the foundation of the Old Republic. Within a year, the war would devolve into a brutal war of attrition, with neither side making any significant gains.

Allying with the Hutts in 442 ABY, the Independent Confederacy of Planets launched an invasion of the Core Worlds Alliance which proved to be the turning point in the conflict. Though the Tripartite War would last an additional seventeen years—finally ending in 459 ABY, with the Devastation of Coruscant—the Core Worlds Alliance would be put permanently on the defensive.

After the war, the Core Worlds Alliance survived as only a small remnant of a few star systems—a mere relic of a government which had once been the dominant galactic power.
