Independent Terra (2068)
Independent Terra is the foundational ideology adopted by League of Independent States (and its predeceasing entities).
In the years since the Autonomous Movements broke out, explicit forms of independentist ideas were given rise in the frontier regions, some branches were eventually developed into radical ideologies adopted by anti-UE entities, including the most well-known ideology of "Independent Terra", which advocates independence revolution against centralists and Earth supremacists, ultimately liberating mankind by overthrowing United Earth and re-establish a new true liberal government on Earth that respects human rights and treat individual colonies as equals.
As colonists were often considered to be the far lower echelons of society than native residents of Earth, the ideas of Independent Terra were even openly welcomed by some colonies beyond frontier regions that were also dissatisfied with authorities on Earth.
Discovery of Terra Nova, the first earthlike planet discovered by humanity in outer space, in 2074 applied an significant impact on the core ideas of Independent Terra ideology, which led to an ideological split within - Pro-revolutionist which continued the original idea of uproot ruling class on Earth, and Second-Terra-ist (SeT-ist) that suggests rivaling Earth influence by establishing liberal government on Terra Nova.
Independence Coalition (2072)
The potential instability associated to the spread of independentist ideologies during the Autonomous Movement were not left unnoticed by United Earth government. Immediately identifying such ideologies as dangers to governmental and political interests, the Security Council increased CLEI presence in frontier regions and colony sectors with high risk of ideological infiltration, to completely outlaw anti-UE entities.
Soon the anti-UE organizations and Independent Terra supporters found operating campaigns became increasingly difficult under the close watch of CLEI secret police.
In 2072, representatives of anti-UE entities of mainly from the frontier region secretly gathered at Terra Nova, forming the Independence Coalition - the predecessor of League of Independent States, establishing cooperation of running campaigns against UE under the nose of United Earth.
First Contact between humanity and Zolarg Empire (2077)
While the first official contact between United Earth and Zolarg Empire took place at 2080, the actual initial contact took place 3 years earlier (2077), during an encounter in uncharted regions between a black market convoy and a Zolarg prospection ship.
The rumors of the encounter spread quickly in black markets, eventually the piece of intel reached the Independence Coalition. Intrigued, the Coalition concluded with an risky decision - sending a secret diplomatic dispatchment to the Zolarg Ship via the black market vessel, in attempt to establish early relations which could help obtaining crucial support for future military campaign against United Earth.
In 2079, the dispatchment returned with cooperation agreements and an unofficial-and-non-disclosed diplomatic and military cooperation pact from Zolarg Empire, which the Coalition offers human technologies to Zolarg scholars in exchange for material and possible military support of Zolarg expeditionary forces.
The Alpha Draconian Conspiracy and Invasion Plan (~2085)
Since the Insectoid uprising events, Alpha Draconians had been in a difficult situation. The economy over-reliant on expansive and expendable insectoid slave labor had been severely hampered, while the reptilians began questioning the faith and pride of their "all-time invincible" empire.
Taking the Insectoid uprising events as the greatest shame to Alpha Draconians, on Alpha Draconis the dissatisfied reptilian lords and nobles urged Overlord Betah'an taking the responsibility to address the crisis.
To the Lords of Inner Circle (who power, ambitions, cunning and brutality were second to only the Overlord), it was a sign of weakened Overlord. Seeing that as an opportunity to seize the Overlord's power rightfully, the Lords of Inner Circle schemed to remove Overlord Betah'an form the throne.
To Overlord Betah'an, the most effective way silencing his political opponents form the Inner Circle and regaining support from nobles while addressing the crisis at the same time, was to start another conquest. The Overloard carefully selected the most suitable target of conquest - United Earth, which was industrially and economically developed but militarily inferior, non-aware of Alpha Draconians' existance, and possible sowing of internal conflict which allows minimal military efforts to eradicate further resistances.
Terra Nova Incident and Battle of Terra Nova (2087)
Burdened by outrageous taxation set by United Earth over the colonies outside Solar-Sphere region since 2079, Terra Nova was the first colony openly boycotting the tax policies of United Earth, refused to deliver tax payments to General Assembly. General Assembly responded the boycotting by enforcing embargo over Terra Nova, followed by immigration interdiction and military blockade, however all failed with little effect on this almost self-efficient colony.
The Independence Coalition, after years of covered military preparation, saw the incident on Terra Nova provided a narrow but the best opportunity to start what they had planned long ago - a revolutionary war to liberate colonies from tyranny of United Earth. Before the military blockade was enforced, the Coalition sneaked additional military personnel to their branch in Terra Nova.
Heat of the debates over follow-up actions against rebellious acts of Terra Nova lasted for months in General Assembly, politicians arguing the effectiveness of measures used to force Terra Nova giving in, while anti-UE organizations on Terra Nova kept provoking United Earth by rallying local people protesting around governmental administrative facilities. Eventually in 2087, with support of politicians who worried Terra Nova incident would evolve into a copy of of Autonomous Movement in 2068, along with manipulation by Alpha Draconian covert agents - By reason of "open revolt against United Earth", President Ronald Tracy issued order to mobilize Space Marines 35th Regiment for military occupation of and martial law enforcement on Terra Nova, marking the outbreak of Human Civil War.
Main forces of Space Marines occupied the capital city of Terra Nova and dispersed protesters with minimal resistance within 2 hours of operation. However, few minutes after the complete occupation, the main forces were ambushed and encircled by local militia forces led by commander Beuford P. Tots in the city. By element of surprise and home turf advantage of militia forces, the well-equipped Space Marines in the capital city took a heavy casualty rate of 63% and were forced to retreat by escaping to troop ship in planetary orbit.
Other militia forces on Terra Nova driven Space Marine and UE garrisons of military facilities into defeat in the subsequent skirmishes over the week. Gaining control over majority of surface-to-orbit defense weapons on the planet, Terra Nova militias forced complete withdrawal of Space Marines 35th Regiment and blockade fleet from Terra Nova at the end of Battle of Terra Nova.
After the battle, the colonial congress replaced the original colonial government. The congress officially sent an formal declaration of independence to Earth, which declared Terra Nova is no longer a chartered colony of United Earth, the once "second earth" was then renamed "Independent State".
Founding of the League of Independent States (2087)
Following the stunning success in Battle of Terra Nova, Terra Nova became the common symbol of freedom and liberty. The rest member organizations and entities of Independence Coalition, along with colonies of neighboring colony sectors inspired by the incident, followed by overthrowing local colonial government and sever ties with United Earth.
The independent colonies and members of Independence Coalition then officially founded the League of Independent States on Terra Nova.
Terra-to-Earth Campaign (2087-2088)
With support of Beaconburg Fleet and arms supplier BSA from Independent State of Beaconburg (previously Autonomous Colony of Beaconburg), mercenaries recruited from black markets and volunteers from liberated colonies, the newly founded League quickly launched the first military campaign against United Earth - the "Terra-to-Earth Campaign" (In United Earth perspective, "The Defense of Solar System"), targeting core territories of United Earth around Solar System.
Despite United Earth ordered nationwide general mobilization against LIS offensive, the mobilization progresses at sluggish pace. This had left LIS gaining most of the strategic initiative and speed advantage in the early to mid stage of the campaign, the scattered and underprepared United Earth forces were being wiped out by LIS with relative ease.
Zolarg Entry into War (2088)
In late 2087, United Earth completed the strategic defense planning, finished preparations of constructing solid defenses by concentrating majority of military assets in sectors near Solar System.
LIS forces launched the Ragnarok Offensive in early 2088 spearheaded by veteran units form the earlier stages of Terra-to-Earth Campaign, in hope to break the defense lines. However, outmatched by United Earth in terms of superior quantity of troops and supplies, the warfare of attrition eventually blunt the LIS offensive, which LIS forces took significant losses.
Knowing crippled forces stood little chance against possible full strategic counterattack of United Earth, LIS urgently needed to delay United Earth from taking initiative. Shortly after the setback, LIS decided to play their trump card - their secret ally, Zolarg Empire.
Using the missile base (deployed with newly built IWSM which its strike range can reach and cover the entire Solar System) established by LIS and (unexpected) assassination of United Earth President Ronald Tracy as distraction, Zolarg Empire responded to LIS call, sent a full battegroup of Expeditionary Force attacking the other side of United Earth territory, forcing United Earth to fight a war of two fronts.
Despite the two-front strategy did divert pressure from LIS, however, as neither side held major advantage over another, the war turned into a stalemate.
Barracuda Blues Event and Preludes to Alpha Draconian Invasion (2088)
In the heat of Human Civil War, Alpha Draconians sneaked groups of pioneer probes into human territory, constructed portal gates in the unnoticed corners where strongholds were set up for preparations of Overlord's surprise invasion plans.
Lords of Inner Circle had been trying to foil the Overlord's plan from the beginning. By a margin of rare opportunity, one covert operative affiliated to Lords of Inner Circle managed to sabotage the cloak device in secret base on planet Barracuda Blues, exposing the dormant portal and droid battlegroup at the site to United Earth and LIS military.
Upon the discovery of the unknown alien facility on Barracuda Blues, both United Earth and LIS dispatched their own task force trying to seize the alien technology that could change the tide of battle. Violent skirmishes broke out between two sides, contesting control of the facility.
As the news on Barracuda Blues were delivered to Zolarg Expeditionary Force. Familiar with Alpha Draconian cunning strategies, the Insectoids immediately identified the alien facility an Alpha Draconian invasion base. The Zolarg Expeditionary Force then sent their urgent message to LIS ally, warned that such discovery was a curse rather than blessing, and presented worries of this war involved orchestrations of Alpha Draconians, the greater evil they were yet to know.
Already at the edge of dishonoring the reptilian ancestors, the sabotage in invasion base on Barracuda Blues and earlier unexpected entry of Zolarg Empire into the war had left Overlord Betah'an with no choice other than launching a premature invasion.
Battle Against Alpha Draconians (2088-2089)
Caught off guard by surprise, near half of the human forces were obliterated by superior war machines of Alpha Draconians during the initial stage of Alpha Draconian invasion.
With a common enemy, military and political representatives of United Earth, LIS and Zolarg Expeditionary Force met on Earth. Shortly, ceasefire agreements were reached, and an temporary alliance against Alpha Draconian invasion was formed.
The alliance organized several joint operations to strategically delay Alpha Draconian invaders with varying outcome, buying time for LIS and United Earth to replenish losses and regroup respective fighting forces.
In mid 2089, United Earth finished reconstruction of the space armadas, later achieved decisive victories in several space battles against Alpha Draconian warfleets, regaining the space superiority and the tables turned to alliance's favor.
With support from United Earth fleets and exploiting the weakness of long replenishment cycle and inferior quantity of Alpha Draconian forces, alliance forces successfully overwhelmed Alpha Draconian forces, storming major invasion bases. The destruction of the largest but last portal gate stronghold during Battle of Barracuda Blues marked the decisive defeat of Alpha Draconian invaders.
Continuation of Human Civil War (2089)
As Alpha Draconians called their fleets back to home territory and aborted control of droid armies following the defeat at Barracuda Blues, the temporary alliance finished its purpose and was then dismissed, both sides returned to status of conflict.
However, exhausted and tired of war, it was impossible to continue the war at the original massive, interstellar scale, both sides came up with conclusion that the war must be ended by an decisive battle as soon as possible.
Zolarg Empire then exited war by signing a white peace with United Earth weeks after the alliance had been dismissed.
At last, remaining main forces of United Earth and LIS coincidentally met near the strategically important wormhole highway node, over the planet of Kaiserground. After a week of fierce back-and-forth battle on the planet and in the orbit, United Earth gained complete control of the planet, setting LIS forces on a full retreat, concluding the final major battle in Human Civil War.
