Star Wars Lore
From the Wookiepedia.
Corellians spent the next 200 years reverse-engineering the hyperdrive without the Force tools of the Rakata. A midstep, hyperspace cannons, connected Corellia with other Core Worlds such as Coruscant and Duro. The reinvention of the hyperdrive in circa 25,000 BBY let the afore-mentioned and other worlds become the Core Founders of the Galactic Republic.
While rumors of the Jedi Order's dawn on Corellia were false, the Corellian Jedi did keep a distinct set of traditions that set them apart from other Jedi, including green robes and Jedi Credits.
Corellian Engineering Corporation was founded early on, perhaps before the dawn of the Republic. Corellia Star Drive splintered off CEC in c. 5,000 BBY, but was bought out by CEC in c. 3,000 BBY. CEC was one of the larger shipbuilding firms in the galaxy, and its shipyards were one of the most extensive in the galaxy. Examples of Corellian ships included the CR90 Corellian Corvette, the YT-1300 freighter, and the DP-20 Corellian Gunship.
Corellians were among the first and foremost hyperspace explorers. Within a millennium, the Corellian Run was mapped; the Corellian Trade Route by 5,500 BBY. The Corellians discovered New Plympto in 10,019 BBY, Goroth Prime in 8,000 BBY, and Koboth prior to 219 BBY. They colonized Rabaan (7,299 BBY), Socorro (3,000 BBY), Trulalis, and Trigalis. Corellia was an early trading partner of the Wookiees when Kashyyyk entered the Republic (3,956 BBY).
Almost 10,000 BBY, a spartan sect established a monastery on Kor Vella. During a boom in CEC's popularity, miners discovered ore deposits near the mesa, transforming the Kor Vella community into a luxurious center of tourism and wealth.
In 500 BBY, Corellia allied with Selonia and Drall in a failed attempt to conquer the Federation of the Double Worlds. 30 years later, Corellia attempted to secede from the Republic; although progressing far enough to close its sector's borders and withdraw from the Senate using Contemplanys Hermi, the plan ultimately failed and the system continued as a begrudging Republic member-state.
400 BBY, the elitist Nomad's Retreat in the Nomad Mountains expanded its membership to become a public resort. Over the next few centuries, a village grew around the retreat, known as Doaba Guerfel, and eventually merged with the Retreat, becoming a resort town.
In 380 BBY, a Corellian Jedi named Keiran Halcyon defeated the Afarathu pirates, a sect of Selonian terrorists, whom were trying to kill all Humans on Corellia. The Afarathu were not gone forever, and would plague Corellia during the Galactic Civil War. In 27 BBY, Jedi Master Oppo Rancisis personally defended Corellia during the crisis with Ashaar Khorda.
In 27 BBY, the planet's name was pronounced K'rell by Mitth'raw'nuruodo, but it is unknown if this is the actual name of the planet in Cheunh or if this was on account of Mitth'raw'nuruodo's unfamiliarity with Basic, or indeed if he even knew of the existence of Corellia prior to his first contact with Humans.
In 22 BBY, in the months leading up to the Clone Wars, Corellian Senator Garm Bel Iblis and Diktat Shyla Merricope withdrew Corellian Sector from the Galactic Republic in protest of the Military Creation Act. Bel Iblis invoked Contemplanys Hermi, an obscure clause in the Galactic Constitution that allowed for "meditative solitude." 23 Corellian Jedi returned to the Jedi Temple on Coruscant, including Jedi Master Nejaa Halcyon. This attempt to insulate the system failed and Corellia, like the rest of the galaxy, was soon embroiled in the turmoil of the Clone Wars. Though the planet was spared an invasion or aggressive military action, presumably the intense fighting on nearby Duro weakened its already troubled economy. The Corellian Sector was heavily fortified, but the CIS fleet bypassed it through the Deep Core to attack Coruscant 19 BBY.
With the declaration of the New Order, Diktat Dupas Thomree made a deal with Palpatine: Thomree could govern Corellian Sector as he wished (mostly free of Imperial mandates) as long as he paid taxes, war material, and homage to the Emperor. Immediately after the start of the New Order, Corellia was wracked by anti-Imperial protests.
The Republic's planetary Governor of Corellia, Fliry Vorru, became the Imperial Moff of Corellian Sector. The Moff was a lenient ruler, turning a blind eye to crime, being more interested in greater power, and was considered a rival of Palpatine. In 7 BBY, Vorru was sent to Kessel after being framed by Prince Xizor. This allowed Xizor to set up his Black Sun lieutenant Zekka Thyne as criminal kingpin on Corellia.
Public peace was maintained by the Corellian Security Force, a fiercely proud organization whose members enjoyed an almost familial sense of loyalty and camaraderie. Officers of CorSec usually followed their parents or siblings into the organization, donning the gray and khaki uniforms as part of a longstanding tradition. Rostek Horn, his adopted son Hal Horn and his son Corran Horn are a perfect example of the multi-generational CorSec legacy.
As Corellians were drafted into military service for the Empire, so as to deal with the growing Rebellion, the overall security of the sector decreased. Pirates took advantage of the opportunity that presented itself and grew more brazen, launching many raids upon starships that used nearby trade routes.
In 2 BBY, Diktat Dupas Thomree died. He was replaced by Daclif Gallamby whom was little more than a puppet of the Imperial Governor. At this time, Thrackan Sal-Solo went underground and began plotting secession.
Following the abandonment of Massassi Station, the Rebel Alliance established a base on Corellia in 1 ABY before moving on to Hoth. That same year, Gowix Computers moved its HQ to Corulag.
In 2 ABY, the Corellian Merchants Guild was banned from the Corporate Sector. The defecting General Crix Madine was rescued from an Imperial ambush in Coronet City by Rogue Squadron and Han Solo.
In 3 ABY, Zekka Thyne was captured on Corellia by Colonel Maximilian Veers and Grand Admiral Thrawn. During this action, Thrawn placed a tracking device on a freighter that led the Empire to the Rebellion at Derra IV.
In 4 ABY, a week after the Battle of Endor, Alliance pilots from Rogue Squadron, as well as Ten Numb and Han Solo, were ambushed by Imperial forces on Corellia. A large amount of Imperials streamed into the planet following the death of Palpatine, giving new power to pro-Imperial factions on the world. A large Imperial fleet was soon sent by the Imperial Ruling Council to defend the world and its shipyards, including forces from Ord Mirit.
Six months after Endor, this fleet was one of the most powerful concentrations of Imperial might anywhere in the Core Worlds, consisting of twenty-five Imperial Star Destroyers under Admiral Jaeffis—by comparison, Kuat had just fifteen Star Destroyers, and Corellia's defenses were scheduled to be even more heavily reinforced when Admiral Roek arrived to assume overall command, with the Super Star Destroyer Aggressor and five more Imperial-class ships.
In spite of this massive defending presence, the Rogues returned to Corellia to rescue Fyric Fel and Wynssa Starflare from their kidnappers.
In 5 ABY, the Imperial Intelligence liaison officer with CorSec, Kirtan Loor, ordered CorSec to attack "Rebels" of the New Republic. Many CorSec officers would not cooperate, believing CorSec answered only to the Diktat and not to the Empire, and was for fighting criminals rather than "Rebels."
One such officer, Corran Horn, was targeted by Loor for assassination, and fled the planet. He was soon followed by fellow officers Gil Bastra and Iella Wessiri, as well as Iella's husband Diric Wessiri, all of whom faked their own deaths. In the light of this lack of cooperation, the Diktat dissolved CorSec and replaced it with the pro-Imperial Public Safety Service.
By 6 ABY, Grand Admiral Danetta Pitta had taken command of the Imperial forces at Corellia, largely by bribing the Diktat, although it is likely that both Pitta and Gallamby remained nominally loyal to Imperial Center. They were challenged by Josef Grunger, who had seized control of Aggressor and possibly some other elements of the defending fleet, and who was now aiming to claim the Imperial throne. As Grunger moved to seize control of Corellian space, he clashed with Pitta at the Battle of Tralus, which left both Grand Admirals dead, Aggressor and Pitta's torpedo sphere destroyed, and both fleets badly mauled.
It is not clear how effective the Imperial military presence at Corellia was after Tralus, but, the New Republic was slow to take control, and the Diktat remained in power as late as 12 ABY. It was probably only after this date that Gallamby withdrew to hiding in the Outlier systems, with Thrackan Sal-Solo and other Imperial functionaries;
Due to the many Corellian fighters serving in the Rebel military, Corellia had long been accorded a leading political role in the Alliance, and now, with countless Corellian expatriates at large within New Republic-held territory, the planet was represented in absentia by Doman Beruss on the New Republic Provisional Council. As an unhappy consequence, many Corellian expatriates loyal to the New Republic were forbidden from returning to their homeworld by the Diktat, so the Corellian Sanctuary was built on Coruscant to honor the war dead and provide a focus for the community.
In circa 12 ABY, Corellian Sector finally joined the New Republic. Diktat Daclif Gallamby was replaced by the New Republic-appointed Governor-General Micamberlecto of Froz to administrate Corellian Sector. The New Republic Medical Institute was established on Corellia.
However, the New Republic government was almost ousted when Thrackan Sal-Solo usurped power during the Corellian Crisis in 18 ABY, murdering Micamberlecto and declaring himself Diktat. He was defeated and Marcha of Drall was made Governor-General.
Sal-Solo tried again to restore Corellian independence and actually managed to get elected Governor-General after his attempt to control Centerpoint Station during the Battle of Fondor, which ended in disaster for a New Republic/Hapan task force at Fondor in 25 ABY. This resulted in Marcha's resignation.
The Jedi Master Eelysa maintained an eye on Sal-Solo's Centerpoint Party and escaped Corellia with the Solos in 26 ABY after being injured, only to return upon her recovery. A year later, Eelysa was killed by a voxyn on Corellia, although Corran Horn and his wife Mirax Terrik managed to escape another voxyn.
In 14 ABY, Kyle Katarn and Jaden Korr went on a investigation mission after receiving reports of cult activity in Coronet. Upon receiveing a distress call from a mag-lev train, Jaden and Kyle found out that the Disciples of Ragnos were behind the attempts to blow up the train. Korr eventually stopped the bomb and the train, and Katarn destroyed mercenary cargo ships successfully, thus ending the Disciples of Ragnos presence there for the time being.
In 28 ABY, a year after the Fall of Coruscant, Sal-Solo traveled to Yuuzhan'tar, in an effort to gain their help in expelling the New Republic, but was instead forced to lead the Peace Brigade, and was impeached as Governor-General and kicked out of the Centerpoint Party. Corellia remained a loyal member of the New Republic, and later the Galactic Alliance.
In 40 ABY, following the political unrest sparked by a disastrous Jedi mission to uncover an illegal missile factory on Adumar, Corellia joined several other worlds in resisting the Galactic Alliance. In response the Galactic Alliance launched a preemptive strike on and above the planet Tralus in the Corellian system in an attempt to bring the rogue worlds to heel.
Unfortunately, this only widened the divide between the Galactic Alliance and the rebellious worlds. Even worse, the furious Corellians launched a counterstrike, thus worsening the confrontation even further and turning it into a full scale war. Corellia would be joined by Commenor, Bespin, Cassin, elements from the Corporate Sector, Adumar, and Fondor.
During the insurrection, the government of the Corellian system was led by a Prime Minister, and each of the five worlds had a Head of State. The systems' military was led by a Minister of War and answered to the Prime Minister. At the start of the uprising, Aidel Saxan was Prime Minister and Thrackan Sal-Solo was the Head of State of Corellia. In the midst of chaos the Galactic Alliance made its first strike at Corellia, starting a full scale war. While all of this was going on Thrackan Sal-Solo was assassinated by his cousin Han Solo with the help of Boba Fett and Mirta Gev.
During the war, the Corellian leadership planned on drawing the Hapes Consortium into the war on their side by assassinating its Queen Mother, Tenel Ka, and her child, Allana. The result of their plan failed as the Queen Mother and her daughter survived and most of the Hapans allied with the Corellian Alliance were captured or killed during the Battle of Hapes.
