The '''Insurrection'''<ref name="ch">'''[[Halo: Contact Harvest]]'''</ref> is the proper name given to an undeclared civil war fought between [[Earth]]'s primary military, scientific, and exploratory agency, the [[United Nations Space Command]] and various loosely organized groups of rebels, collectively known as the [[Insurrectionist]]s, over control of the [[Outer Colonies]], which [[Callisto Incident|began]] in the year [[2494]].

Initially confined to a few systems, the fighting spread across human-controlled space in only several years; as the conflict escalated further, even some [[Inner Colonies]], as inwards as the [[Epsilon Eridani system]] and even the [[Sol system]] itself, were targeted by rebel militants and terrorists.<ref name="goo">'''[[Halo: Ghosts of Onyx]]'''</ref> What had once been widespread support for the Insurrectionists quickly dried up at the outbreak of violence. Though they started out targeting only military and Colonial Administration targets, as the UNSC counterinsurgency operations began, more and more innocent people were caught in the crossfire.<ref>'''Halo: Contact Harvest''', ''page 61''</ref>

The Insurrection claimed millions of lives between the late 2490s and the mid-2520s. The various rebel groups had become extremely adept at creating improvised explosive devices difficult for the UNSC to detect, and therefore stop, and had struck many high-profile targets, [[National Holiday|even in orbit]] above [[Reach]] itself. Some opponents of the war believed the simplest solution was to simply give the rebels their autonomy - for the UNSC to pull out, and let the rebels have their independence. However, the value of the colonies made them simply too important to abandon, as it would bankrupt the Inner Colonies.

 

 

After the [[Battle of the Citadel|end]] of the war in [[2552]], some of the surviving Insurrectionist groups—as well as all-new ones—proceeded to resume their fight against Earth. This led to their resurgence [[Post-Covenant War conflicts|after the war]], starting with the [[New Colonial Alliance]] [[Raid on UNSC Infinity|raiding]] the [[UNSC Infinity]] in [[2553]], mere months after the Covenant threat had ended. In the post-war insurgency, [[Covenant remnants|Covenant splinter groups]] have sided with the rebels on a number of occasions.<ref>'''[[Kilo-Five Trilogy]]'''</ref><ref>'''[[Halo: Escalation]]'''</ref><ref>'''[[Halo: Last Light]]'''</ref> The Insurrection remained active at the time of the [[Guardian]]s' [[Created conflict|emergence]] across human space on [[2558#October|October 28, 2558]].{{Ref/Reuse|HtTS2E6}}

===Origins===

The [[Unified Earth Government]]'s first wave of extrasolar colonization took place between [[2362]] and [[2390]], resulting in the formation of the prestigious [[Inner Colonies]]. During the century that followed, new colonies were established at an even more rapid pace as the technologies involved became more widely available and affordable; the worlds settled during this period would become the Outer Colonies. Many of the Outer Colonies were established to supply goods for the Inner Colonies and [[Earth]] and entire worlds were established for the purposes of [[agriculture world|agriculture]] or mining. Earth and the Inner Colonies became exceedingly dependent on resources produced by the Outer Colonies, prompting Earth to take steps to ensure they stayed loyal to its authority.<ref>'''[[Halo Encyclopedia (2009 edition)]]''', ''page 43'' (2011)</ref>

From the beginning, the Outer Colonies were bound to become more unstable than the Inner Colonies. Whereas the original settlers of the latter had been carefully selected from Earth's finest, by the time the Outer Colonies were created the recruitment standards had loosened considerably and were no longer as strictly supervised. Many of the corporations contracted for off-world colonization had their interests in obtaining rights to valuable resources, colonial personnel being a secondary consideration: this led to the illegal conscription of colonists or acquiring them from among pardoned criminals. The Outer Colonies also became a haven for Earth and Inner Colony citizens unhappy with the Earth government or otherwise looking for a fresh start, and many fled to the Outer Colonies through both legal and illegal means.{{Ref/Reuse|history}}

 

Following the rapid volumetric growth of the region of space controlled by the human race throughout the [[Domus Diaspora]], the UEG found it increasingly difficult to maintain its hold over the Outer Colonies, hundreds of which were scattered across exceedingly large swathes of space. By [[2490]], the Outer Colonies surpassed the core worlds in number by several hundred. Despite their more discrete composition, the Outer Colonies proved an ample breeding ground for a strong nationalist sentiment among their citizens which in turn led to their perceiving the Earth government—and the UNSC which imposed its will—as a draconian outside force.{{Ref/Reuse|history}} Civil disobedience was not uncommon, often taking the form of refusal to pay taxes and the establishment of unauthorized settlements outside government oversight.<ref>'''Halo: Evolutions - Essential Tales of the Halo Universe''', "[[Pariah]]"</ref> On some cases, the [[Colonial Administration Authority]] made concessions to ameliorate the situation; for example, the registration of births to government records was kept voluntary.<ref name="onyx82">'''Halo: Ghosts of Onyx''', ''page 82''</ref> On the other hand, most Outer Colony citizens took advantage of the benefits offered to them by the CAA, including the free [[Outer Colony vaccination program|vaccination program]].{{Ref/Reuse|onyx82}}{{Ref/Reuse|journal}} [[UNSC Navy]] Admiral [[Gabriela Castaneda]] was among the more profound voices advocating for diplomacy, though ultimately served as an impressive tactician and leader during the conflict towards the end of the 25th century.<ref>[https://www.halowaypoint.com/en-us/news/outpost-discoveries ''Halo Waypoint'': Canon Fodder - Outpost Discoveries]</ref>

As a result of the growing rumblings of discontent, many inhabitants of Earth and the Inner Colonies began to feel threatened by the Outer Colonies surrounding them. The UEG and its colonial governing and military entities—the CAA and initially the Colonial Military Administration—continued to maintain their military presence and economic control over the colonies with trade restrictions and taxes, engendering further dissatisfaction among the colonists and provoking the more radical secessionist elements.{{Ref/Reuse|journal}} Civilian uprisings against UEG rule began to break out between [[2475]] and [[2483]]. The CMA's response was swift and severe, but their heavy-handed tactics backfired, only hardening the resistance against them and further radicalising the population against them. Stronger and more aggressive dissidents began to take to the political stage, plunging the colonies further into civil unrest.{{Ref|'''''[[Halo Mythos: A Guide to the Story of Halo|Halo Mythos]]''' - Domus Diaspora; The Insurrection'', Pages 54-61|Name=MythosDDandInsurrection}}

 

While outspoken and violent resistance against Earth was initially confined to disparate insurgent organizations, even the leadership of some Outer Colonies would eventually be sympathetic to the insurrectionist cause.{{Ref/Reuse|journal}} Eventually, the [[People's Occupation]] and [[Secessionist Union]] were formed, uniting many of the dissenters under a single banner. In [[2487]], these newly established organisations jointly submitted formal requests for independence to the UEG on behalf of a dozen colony worlds.{{Ref/Reuse|MythosDDandInsurrection}} As well, as these sentiments spread, even some scattered elements of the CMA became increasingly sympathetic to the rebels, eventually providing them with information, funding and equipment. The involvement of these sects of the CMA with the rebels went public in [[2497]], leading to the organization's gradual dismantling and its supplantment by the UNSC as the primary military force in the colonies.{{Ref/Reuse|HE34}}

 

In [[2491]], [[Elias Carver|Dr. Elias Carver]] presented a set of theories known as the ''[[Carver Findings]]'' to the [[UNSC High Command]]. According to a projection algorithm devised by Dr. Carver, social order in the Outer Colonies would break down completely in the near future. To stabilize the colonies, Carver recommended a swift and extensive military action on part of the UNSC.<ref>'''Halo Encyclopedia: The Definitive Guide to the Halo Universe''' ''page 44''</ref> Carver's critics asserted that the situation between the core worlds and the Outer Colonies could be stabilized through diplomacy over enough time; however, the UNSC military adopted the ''Carver Findings'' as their standard model for the years to come and sought to curb any major unrest with military intervention.{{Ref/Reuse|journal}} In the same year, the UNSC resurrected the mothballed [[ORION Project]], creating the first generation of supersoldiers designed to surgically remove rebel leadership.<ref>'''Halo Encyclopedia: The Definitive Guide to the Halo Universe''' ''page 33'' (2011)</ref> Carver's proposal also informed the creation of the subsequent [[SPARTAN-II Program]], although by the time of its creation the predicted scenario was even bleaker: an endless, apocalyptic civil war between the Inner and Outer Colonies.{{Ref/Reuse|journal}} After the onset of the [[Human-Covenant War]], the Spartans were re-prioritized to deal with the new alien enemy, becoming exceedingly successful and well-publicized in this role.

Perhaps the most notorious instance of the brutal and heavy-handed approach the UNSC and CMA took to quelling rebellions in the late 25th century was that of [[Far Isle]]. In [[2492]], in the midst of the rising tensions throughout the colonies, Far Isle was among the first of the colonies to go into a full-scale revolt. Despite their best efforts, the UNSC were unable to contain the rebellion, and as a result, they resorted to [[nuclear weapon]]ry, razing the entire colony and leaving no survivors from the populace. They subsequently declared [[Bandersnatch|Code: BANDERSNATCH]], indicating a major radiological- or energy-based disaster.{{Ref|'''''[[Halo: Ghosts of Onyx]]''' - Chapter Twenty-One, Page 183 (2006 edition)''|Name=GoOFarIsle}}{{Ref|'''''[[Halo Encyclopedia (2009 edition)|Halo Encyclopedia: The Definitive Guide to the Halo Universe]]''' - Locations: Human Colonies'', Page 288 (2009 edition); Page 300 (2011 edition)|Name=EncyclopediaFarIsle}}{{Ref|'''''[[Halo: Mortal Dictata]]''' - Chapter Ten'', Page 291-292 (2014 edition)|Name=MortalDictataFarIsle}}

Although not usually acknowledged as the inciting incident of the Insurrection,{{Ref/Reuse|MythosDDandInsurrection}} the destruction of Far Isle caused multiple larger rebellions elsewhere, and was considered a significant factor in motivating the Insurrection as a whole.{{Ref/Reuse|EncyclopediaFarIsle}} Far Isle remained a driving force for the hatred that many individuals bore for the UNSC and UEG even as late as [[2553]], in staunchly independent colonies such as [[Venezia]].{{Ref/Reuse|MortalDictataFarIsle}}

On March 2, 2494, the battle group eventually found the ''Callisto'' in the [[26 Draconis System]]. All of the ships fired six [[Ares missile]]s at the renegade corvette. However, the ''Callisto'' managed to avoid destruction by maneuvering behind an [[asteroid]]. The insurrectionists then detonated a nuke hidden inside the asteroid before hand, launching the debris toward the UNSC ships.

The ''Buenos Aires'' was engulfed in the explosion and destroyed, and the other two ships were seriously damaged. [[Second Lieutenant]] [[Preston Cole]], as the only living or conscious officer aboard the bridge of the ''Las Vegas'', took control of the vessel. He signaled the ''Callisto'', activating the ship's distress signal and requested medical aid for the wounded. When the ''Callisto'' docked with the ''Las Vegas ''in order to take command of the ship, Cole detonated the ships last Ares missile, which had been planted inside the docking bay, critically damaging the ''Callisto''. Cole then bluffed by opening the empty missile silos on his ship and ordered the ''Callisto'' to surrender and allow ''Las Vegas''{{'}}s AI to take control.

As the fighting spread, the Outer Colonies became a battleground between the [[UNSC Navy]] and the rebels' makeshift fleets. In June [[2501]], an insurgent captured [[UNSC frigate]], the ''[[Bellicose|Bellerophon]]'', was pursued for the third time by the {{UNSCShip|Gorgon}}, commanded by [[Preston Cole]], into the [[Theta Ursae Majoris system]]. After a chase and battle, in which the ''Bellerophon'' managed to dodge a MAC round using excellent tactics, the ''Gorgon'' was contacted by the ''Bellerophon'', renamed the ''Bellicose''. A short exchange of taunting messages followed, and then Cole let the ''Bellicose'' escape. After laying traps in five systems over a course of three months, Cole had yet to find the captured ship. Several months later, Cole was married to [[Lyrenne Castilla]], who was also pregnant.

 

In [[2513]], the UNSC initiated Operation: TREBUCHET, one of the largest operations in UNSC history; spanning ten years and costing hundreds of thousands of lives, the goal was to root out the Insurrectionists and impose order in the Outer Colonies.

The fighting eventually spread to the [[Epsilon Eridani system]]. By [[2524]], the fighting involved in Operation: TREBUCHET alone had taken over a million lives, the majority of which being civilians. In that year, a Marine battalion was posted at the colony world of [[Tribute]], commanded by Lieutenant Colonel [[Aboim]] and supported by the corvette {{UNSCShip|Bum Rush}} and air support from [[AV-14 Hornet|Hornet]]s. The battalion attempted to put a stop to rebel bomb makers near the city of [[Casbah]]. Two special warfare squads, led by [[Staff Sergeant]]s [[Avery Johnson]] and [[Nolan Byrne]], were involved in disastrous operation in June. Byrne's team was killed during a hostage situation at a [[Jim Dandy]] restaurant near Casbah city; thirty-eight civilians, three Marines, and two rebels were killed in the bombing. Byrne and Johnson were pulled from the system, and were later sent to [[Harvest]].{{Ref/Reuse|ch}}

 

An armed insurgency also occurred on the colony of [[Epsilon Eridani IV]], which the legendary [[Admiral]] [[Preston Cole]] was sent to put down.<ref>'''[[Halo Wars: Official Strategy Guide]]''', ''page 22''</ref>

[[File:Watts' Capture.png|thumb|250px|The capture of Col. Robert Watts.]]

In the year [[2525]], a [[SPARTAN-II]] team, led by [[John-117]], went on a mission to infiltrate and capture rebel leader [[Colonel]] [[Robert Watts]]. The Spartans sneaked on board via the ''[[Laden]]''. Once on board, they located a cargo that contained luxury items such as [[Sweet William cigar]]s and [[champagne]], verifying Watts' presence.

Following the [[Covenant]] [[First Battle of Harvest|attack]] on [[Harvest]] and the onset of the [[Human-Covenant War]] in [[2525]], Operation: TREBUCHET was put on halt by the UNSC. The [[Office of Naval Intelligence]] Section II sent emissaries with full disclosure on events at Harvest to warn Outer Colony leaders. The UNSC made the offer that they would cease hostilities toward the Insurrectionists if they worked to bolster their planetary defenses and ended their attacks on UNSC ships. The rebels believed it to be a trap and responded with laughter, only to face a harsh dose of reality as the Covenant began laying waste to colony after colony.{{Ref/Reuse|journal}}

As the war progressed, insurrectionist activity continued to decrease, apart from isolated conflicts such as the [[Mamore insurrections|insurrections on Mamore]] and incidents on [[Harmony]] and [[Reach]].<ref name="actual">'''Halo: Reach''', campaign level ''[[Noble Actual]]''</ref> This was in part due to the common enemy of the Covenant and the desperate situation humanity found itself in, but also the near-total decimation of the Outer Colonies which had served as the rebels' bases of operations. However, the desire for independence continued to linger on many remaining colony worlds. Using the situation to their advantage, entire colonies under Insurrectionist control intentionally cut themselves off the UNSC's [[communications relay]] network during the war, anticipating to resume their operations later on.<ref>'''Halo: Glasslands''', ''page 68''</ref> By 2552, Insurrectionist activity on Reach was still common enough for the UNSC to suspect rebel sabotage when a [[Visegrad Relay|local relay hub]] went dark, although this turned out to be the work of a Covenant pre-invasion party instead.{{Ref/Reuse|actual}}

Although Insurrection activity continued over the Human-Covenant War, with the last documented conflict as late as [[2537]],{{Ref/Reuse|goo}} the high-profile operations and major battles which characterized the early years all but subsided after the beginning of the war. The vast majority of humanity had united under a single banner in order to fight for the survival of their entire species, even the ununited insurrectionists themselves would fight against the Covenant ultimately helping the war effort.<ref name="Halo Legends">'''[[Halo: Legends]]''' "[[Origins]]" - '' "When this new foe emerged and declared war against humanity, you finally united under a single banner. And the weapons you so carefully constructed to control your own baser instincts, were now aimed not at yourselves, but against a deadly opponent. In pursuit of a shared goal, the very survival of your species."''</ref><ref>'''[[Halo: First Strike]]''', ''page 255''</ref> Any engagements between the UNSC and the rebels following the Covenant attack appear to have been relatively low-key, often involving covert missions carried out by special forces such as Spartans. As a result, the generation that had grown up during the war had no knowledge of the Insurrection's persistence and considered the entire civil war as having occurred long before their time.<ref name="glass216">'''Halo: Glasslands''', ''pages 216, 447''</ref>{{Ref/Note|The Insurrection was originally stated in ''Halo: First Strike'' to have died out after the onset of the Human-Covenant War, as the appearance of the Covenant left most Insurrectionists concluding that staying with the UNSC was a lesser evil to outright annihilation. However, later sources such as ''[[Halo: Ghosts of Onyx]]'', ''[[Halo: The Cole Protocol]]'' and  ''[[Halo: Reach]]'' retcon this, with ''The Cole Protocol'' stating that the Insurrection continued in some capacity at least until 2535, and ''Reach'' saying that it was still ongoing as of 2552. The 2010 rerelease of ''[[Halo: First Strike]]'' was modified to accommodate this change. However, more recently, in ''[[Halo: Glasslands]]'' and ''[[Halo: The Thursday War]]'', it is maintained that the Insurrection subsided after the start of the Covenant War; characters such as [[Malcolm Geffen]] and [[Vasily Beloi]] consider the entire notion of conflict between humans a thing of the past. In order to reconcile this, it can be assumed that the characters in question were unaware of the continuation of the conflict, or at least the extent of it.}}

{{Main|Operation: SMOKING ACES}}

By 2531, Insurrectionists had repeatedly had its operations disrupted by a four-man team of Spartan-II supersoldiers known as [[Blue Team]]. The team disrupted Insurrectionist operations including [[Station Jefferson]], the destroyer ''[[Origami]]'' and a saboteur cell on Reach, as well as an incident in [[wikipedia:Micronesia|Micronesia]], and a high-explosives manufacturing facility at an unspecified location.<ref>'''Halo: Ghosts of Onyx''', ''page 36-37''</ref>

===Post-war resurgence===

Of particular significance to the reemerging insurrectionist movement was the colony of [[Venezia]], which had become a major center for rebel operations during the war, when its [[Venezian militia|insurrectionist government]] had declared itself sovereign and eliminated the local CAA authorities.<ref name="glass86">'''Halo: Glasslands''', ''page 86''</ref>

 

 

 

 

 

 

Not willing to let the Guardian site fall into the NCA's hands, ONI tasked [[Commander]] [[Maya Sankar]] to go undercover as the [[insurrectionist]] leader "FERO" and gather information by infiltrating the NCA, with the help of the [[AI]] [[Black-Box]]. After rendezvousing with her contact [[Ari Rezneck]], they moved into the NCA encampment and discovered that the insurgents were celebrating the apparent death of [[Spartan-II]] [[John-117]]. ONI discovered Zane's presence in the camp and had warned Sankar of an incoming UNSC airstrike. Gaining what information they could, they attempted to leave but the camp was put on lock down and were then approached by Zane herself. Zane revealed both of them to be ONI operatives, killed Rezneck, then attempted to kill Sankar but was halted when the airstrike began. As the compound was bombarded, Sankar fled the planet and Zane with her NCA forces attempted to stop her but failed.<ref>'''[[Hunt the Truth]]''' ''Season 2, Episode 02: FROM FIRE TO BLOOD''</ref>

Tracking down Sankar's group to [[Laika III]], Zane and her NCA forces shot down her ship and pursued her, intending to kill Sankar and then secure the planet's Guardian to use as a weapon against the UNSC.<ref>'''[[Hunt the Truth]]''', ''Season 2, Episode 05: WHERE THE THIRD LIFE SHINES''</ref> During their pursuit, they encountered UNSC and ONI forces and engaged them as the Guardian started to rise.<ref name="HtTS2E6">'''[[Hunt the Truth]] ''', ''Season 2, Episode 06: TRANSENDENCE''</ref>

Ironically, the Insurrection may have contributed to the UNSC's victory and the overall survival of [[humanity]] in the [[Human-Covenant War]]. As [[Codename: SURGEON]] stated in his [[2552]] report on [[Admiral]] [[Preston Cole]]:<ref>'''Halo: Evolutions - Essential Tales of the Halo Universe''', "The Impossible Life and the Possible of Preston J. Cole", ''page 457''</ref>

{{Article quote|History looks upon this time as an unfortunate (and perhaps inevitable?) misunderstanding between Earth and her colonies, but those fighting for the last decade also realize that it was the most amazing piece of blind fortune the human race has ever stumbled upon. Had we not been armed and learning how to fight in space... what would have happened in the years that followed, when we faced [[Covenant|an enemy a hundred times worse]]? Oblivion, no doubt.}}

While the reason for the UNSC's eventual victory was arguably the [[Great Schism]] within the Covenant, from the Insurrection came the [[Magnetic Accelerator Cannon]], [[Titanium-A armor]], [[soft-seal]] technology employed in [[Naval boarding|boarding]] actions, advances in ship-to-ship warfare tactics, the incorporation of the [[Illegal Entry Protocols]] and [[Counter-Illegal Entry Protocols]] into [[smart AI]]s, and above all, the SPARTAN-IIs, all of which would prove crucial in humanity's fight against the Covenant.
