proponents of forming a mutual defense alliance as a great area of their territory bordered the Centauri. Many races acknowledged that a combined force would be more dissuasive or at the worst have a much better chance a Centauri invasion force off. In 2215, the membership in the League of Non-Aligned Worlds was ratified by enough sovereignties to sustain it, although it was a highly informal organization at this time. Many League members approached the Narn, but they refused to join. They were wary of other races as contact with the last two (the Shadows and the Centauri) had been extremely detrimental. Despite this, the League and Narn Regime maintained cordial relations.
By the 2220's the League began to strengthen the structure of the League and form a comprehensive mutual defense plan. Disputes ranging from the diminishing of sovereign rights to contention between races for a multitude of reasons, to the equality of shared resources delayed any real advances in League policy. By 2228 raider attacks and rumors that the Dilgar were preparing for a major war quickly brought the League races together. In 2230 the Dilgar openly assaulted League worlds, forcing the League to hold to its treaty. Despite combining their forces, the League of Non-Aligned Worlds was fighting a losing battle as world after world succumbed to Dilgar conquest and experimentation. The League called upon the major races for assistance in their war with the Dilgar. The Earth Alliance answered and was a major force in defeating the Dilgar. Victory was bittersweet, several League members became extinct and a number of worlds were rendered inhabitable during the war.
While allied with the humans, the League formalized its structure to better interact with the Earth Alliance. Following the war the League formed a governing council. It met periodically to set League policy. Although it had no force of law with the individual League governments, the council set economic and political policy for interaction between member states. League membership was opened up to any starfaring race that wished to join. Membership swelled from a mere fifteen to fifty alien governments. Unfortunately, no major race, who preferred their own governmental structure, joined the League.
The League was temporarily disbanded in 2260 as Shadow influence turned almost all League races against each other. As the League members realized what was being done to them, the League reconvened and joined the Army of Light.
