The League of United Minor Alliances was started by the Chancellor and Secretary of Foreign Relations of The Organisation of Imperial Nations. Noting that smaller alliances were highly vulnerable to larger, more established alliances, and valuing the freedom of small alliances to exist, due to the greater independence and sense of belonging this gave nations in such alliances, rather than being a small cog in a huge machine, Chancellor Dark Wizard and Secretary of Foreign Relations Cripple announced that they were creating a group of small alliances that would remain independant of each other, but would swear to provide aid and military help to the other alliances in the case of an attack, thus providing the total military power of a large alliance, while maintaining an alliance's independence.
Several alliances immediately showed interest and joined LUMA, although others had reservations. Each alliance was allowed two official delegates to the LUMA council, where joint decisions would be made. A Charter and Logo were quickly agreed and LUMA started meeting.
However, LUMA showed signs of being too slow to reach a decision. This was reflected in the NPO 'axis' vs. CoaLUEtion war, where no official decision was ever reached, and as a result of the war, several alliances fell apart. At the time, the Organisation of Imperial Nations seemed to be dying also. However, in August 2006 after Chancellor Dark Wizard resigned, the former Secretary of Foreign Relations, Cripple, was appointed temporarily. OIN was regenerated and many changes were made to its structure. Because LUMA had also slowed down to hibernation point, a decision was made to regenerate LUMA in a similar way to OIN, but this was not successful.
Although LUMA itself was not particularly succesful, it was the first example of an alliance 'bloc', with multiple alliances agreeing to co-operate in military and economic matters (and was distinct from previous groups of inter-allied alliances in that it styled itself a bloc, and involved discussions between all member alliances in one place). Thus it does have some historical significance; over time the concept became a major feature of the game, with many blocs involving much larger member alliances now existing.
