1st Space War

The 1st Space War also known as the UEF-Tribal War was a short four year war between the UEF and several independent space clans, as well as the colonies of Ackur and Orlingas which rebelled against the Federation in support of the clans due to them having heavy influence on both colonies' politics and economies. 
A short war but bloody war, both sides suffered heavy casualties and at least 8 million civillians were reportedly killed in the crossfire. 
The war came to an end after the Azerion's vice commandant, Halios, overthrew Azelas and agreed to a ceasefire. By this point both the Ures and Kinalon Clan had essentially ceased to exist while the Clan of Minalos had already surrendered after suffering a invasion on its homeworld. The colonies, Ackur and Orlingas, had also surrendered with Ackur facing an planetary invasion and Orlingas surrendering peacefully after an element of the 3rd Fleet appeared in orbit. 
== Background ==
Following the beginning of a new era for space, the UEF had explored and colonised many worlds, starting many trade and supply routes necessary for a fair amount of these colonies to thrive and for the Federation's resource pool. Exploitation and rampant space piracy was inevitable with this new era of space travel and was growing on quickly. 
By 2199, space pirating had become a major problem primarily in the Star Sector, Origanius. The space tribes and clans controlled a fair portion of these colonies, disrupting and raiding the space routes, ravaging undefended worlds, influencing them for more leniency and control, and even settling on some newly discovered planets and systems. The major clans and tribes identified were the Azerion, Kinalon and Ures clans who dominated the star sector with the Minalos Clan being the bridge between the three clans and other star sectors. This growing problem in the star sector led to the Federation increasing security in the sector and the growing presence of military forces. However, this did not stop them who in response, simply grew more ferocious in each attack. 
By 2205, the Federation no longer able to tolerate the tribes and clans' exploitation and almost tyrannical control over a portion of its territories, sent an ultimatium. The initial ultimatium was fairly lenient, more akin to a negotiation. The ultimatium demanded the clans cease their pirate activites and raids and undergo a reorganization to Federation control. In addition to arresting specific people within each clan. Should they have accepted, this most likely would've avoided further conflict and existed in a more cooperative manner. However, the leading tribe of the four and representative of the tribes/clans (much to Clan of Minalos' dismay as they had proposed they be the representative to the Federation), House Azerion, instead scoffed at these demands and boasted that they would continue their operations one way or another. 
The Federation was less lenient in its second ultimatum shortly afterwards. The second ultimatum sent only about 4 days later, demanding the clans to cease their operations and be disbanded entirely or face an invasion of the sector. The tribes and clans replied preferring war, beginning the first space war in the Federation's history.

== Aftermath ==
Immediately after the war ended, UEF Military Command underwent drastic reforms and restructuring in order to address poor inter branch coordination, rivalry and overall competing for fire/air support which caused many unnecessary casualties as sometimes fire support would be diverted or outright aborted for a separate unit. The reforms and restructuring saw many commissioned and non-commissioned officers change rank and roles, with some being sent back to training or outright "fired". 
Soldiers at the lower levels had also taken notice to the reforms and began raising concerns about the treatment of the lower level grunts during the war, especially equipment wise, which also garnered support from the remaining officers. This resulted in the concerns quickly going up the chain of command, eventually to the Federation's highest military command, the Federation Military Council. Project Fe-26-84 would later be started to address one of the key concerns of the soldiers and problems during the war, armor and exoskeletons.
