The Tanabiku War, also known as the Thirty Years War, was a galactic war that last lasted from 2120 to 2150. Despite it being called the Tanabiku War, it only encompassed the Daiichi and Daini Quadrants of the Tanabiku Galaxy, with the majority of the fighting being in the Daiichi quadrant. It involved many galactic interstellar states—including all of the great powers—which aligned with either one of the two opposing factions: the Acahkosa, led by the Ecumenes of Azakayana, and the Commonwealth of Systems, led by the Atmoran Empire. The war lasted from 2120 to 2150 and claimed the lives of more than 20 quadrillion people on both sides, making it the deadliest and most destructive conflict in the Tanabiku Galaxy, as well as one of its longest in the modern era.
Atmora's growing imperial ambitions and increasing suspicion of Azakayanese intentions rapidly increased tension in the late 22nd century. A false flag operation conducted by the Atmorans on the warship HMS Astrild gave the Empire a pretext to declare war against the Ecumenes in 2120. The Filuv Lokoltei of Faal Lot Himdah followed soon after to honor its alliance with Atmoran and in response to a preemptive strike by Azakayana on the Lok System. In a series of campaigns spanning from 2120 to 2133, the Commonwealth powers launched an invasion into Azakayanese space, driving Azakayanese forces thousands of lightyears inward before they were halted at the Avand System.
In Year 2134, Azakayana and her allies launched a counter-offensive that spanned the remainder of the war, liberating occupied territories from Atmoran domination and launching their own invasion into Atmoran and Diistaak space. The counter-offensive crippled the Atmoran war machine and forced the Diistaak to surrender in Year 2148. Yet their offensive was slowed down and their own war machine weakened with the usage of the Anqualë, a viral biological weapon that contributed to the most casualties during the war. Despite this, they were able to capture Lythame and force the Atmorans to surrender in 5 March 2150. That same year, the Treaty of Wolfina was signed between the primary participants of the conflict, formally ending hostilities and imposing heavy reparations on the Atmoran Empire and Faal Lot Himdah.
The Tanabiku War greatly altered the balance of power in the Daiichi and Daini Quadrants. The Tanabiku Galactic Forum was established in order to facilitate intragalactic cooperation and dialogue, as well as avert future conflicts. The Ecumenes of Azakayana—no longer able to remain a mostly solitary civilization—emerged from the war as a great economic and military power, and its effective hegemony over the Daiichi-Daini Periphery was virtually unchallenged for the next 100 years. However, many say this time of peace is about to come to an end—with a resurgent Atmoran-Arcadian Empire as well as the rise of expansionist empires from the far reaches of the galaxy, political scientists theorize that another galactic war may take place in the near future.
Background
Azakayana and Atmora had been fighting for territorial and diplomatic influence in the Daiichi Periphery region for centuries. However, the two came together and negotiated the Treaty of Osasakwa. Under the terms of the treaty, Azakayana and the Atmoran Empire agreed to respect each other's spheres of territorial and diplomatic influence in the Daiichi-Daini Periphery, and the two maintained an uneasy peace for the following centuries. However, the Treaty of Osasakwa did not cover their distant colonies that were deep in both the Daiichi and Daini Quadrants, so competition between the two empires continued throughout the late 27th Cycle.
It was in the 28th Cycle that the two nations began to organize alliances to defend against the other. The Atmoran Empire and Faal Lot Himdah established the Atmoran-Diistaak Commonwealth in Year 56, while Azakayana the Three Star League, an entente with Sidima and the Rutharian Suns, in Year 64. The Three Star League later became the Acahkosa in Year 86, becoming a major military bloc in the Daiichi-Daini Periphery. Yet the tense peace between Atmora and Azakayana remained for another century.
In Year 187, the Atmoran government announced the addition of 894 trillion Guiders to the Atmoran military expenditure in a major arms buildup of the Atmoran military. In response, Azakayana responded with its own increase in military spending, and an arms race ensued between the two powers for the remainder of the 2nd Century.

Aftermath
Impact
The number of casualties incurred by all sides in the war vary, since many deaths were unrecorded. Most estimates range between 15 and 25 quadrillion—the overwhelming majority of which were civilians. Many of the civilians died due to unrestricted orbital bombardment, genocide, massacres, disease, and starvation. Over 85% of deaths in the war were sustained by the Acahkosa faction, and nearly 90% of those were Azakayanese deaths. Over the course of the war, nearly a quarter of the population of the Ecumenes were wounded or killed.
As part of reparations to the Acahkosa, the Atmoran Empire was forced to give up 12% of its pre-war territories, with the Glenraven and Lythori Sectors transferred to Azakayana, and the Lissaria Sector transferred to the Rutharian Suns and the Nation of Caphevad. This was followed by forced expulsions of the Atmoran population—33 billion Atmorans were expelled from the Glenraven Sector, and another 19 billion in the Lythori Sector. The few million Atmorans that remained in the now-Azakayanese colonies would become a source of tension between Azakayana and Atmora in the postwar years. In addition, Atmora was to demilitarize all of its assets in its frontier colonies within 30 ly from the Glenraven Line.
