"Every soldier in the Dominion would love to get their hands on some shiny new tech from Umoja. And who can blame them? With their slick white designs and highly-advanced features, the Umojans make quite the impression—even before they fire at you."

- Faction description(src)

The Umojan Protectorate is the nationalized militia and united interstellar political entity of Umoja and other nearby independent colonies.


The Confederacy[]

The Umojan Protectorate was formed in an emergency sitting of the Umojan Ruling Council after it had seen what blatant abuse the Terran Confederacy was capable of when it appropriated nearly all of the mining guilds affiliated with the Kel-Morian Combine at the end of the Guild Wars in 2489.[2][3]

The Protectorate openly opposed a number of Confederate encroachments on its territories, but war was never declared due in part to other threats facing the Confederacy, most notably a crippling guerrilla war led by Arcturus Mengsk,[3] whom the Protectorate had a secret alliance with.[2]

In 2491 the Confederacy decimated Korhal and its population with a massive nuclear barrage. The Umojans continued to support the remnants of the movement, the Sons of Korhal, allowing citizens to sign up as soldiers.[4]

The Dominion[]

When the Terran Dominion was formed, the Protectorate rallied to its side. However, the Protectorate distanced itself from the Dominion when its heavy-handed tactics began to resemble those of the Confederacy.[3]

The Brood War[]

As the Brood War began, the Terran Dominion was unaware of the United Earth Directorate invasion. An alliance between the Confederate Resistance Forces and the UED was formed on the Dominion world of Braxis, capturing its capital, Boralis.[5]

Using codes extracted from there, the Confederates were able to determine Mengsk's schedule; he was visiting Umoja at the time, his first visit to Umoja as emperor of the Dominion, six months after his empire's formation. Mengsk and Dominion general Edmund Duke diplomatically fenced with Umojan politician Ailin Pasteur over how close Dominion vessels could approach Umoja. Mengsk eventually approached Umoja, with only a few soldiers, son Valerian and teacher Master Miyamoto in an obsolete gun cruiser.

Shortly after landing, the Confederates used various jamming techniques to cut off Mengsk from aid and landed approximately 30 soldiers, led by Mengsk's former commanding officer, marine Angelina Emillian. They tried to kill Mengsk. Despite being outnumbered, the Dominion and Umojan forces held off the Confederates (suffering heavy losses). During the battle, Duke's forces took advantage of the jamming and confusion to approach Umoja and destroy the remaining Confederates. Afterward, the Umojans and Dominion officials had to renegotiate Dominion ship movements near Umoja. Mengsk was left with the belief that Umoja was complicit in the attack.[1] This sparked an economic conflict and "shadow war" between the Dominion and the Protectorate.[6]

After the Brood War, the Protectorate adopted the medivac dropship.[7]

Conflict with the Dominion[]

The Protectorate remained ideologically opposed to the Dominion and was widely considered a safe haven for individuals seeking refuge from persecution by the Dominion. The Protectorate funneled resources into advanced technological research, established a far-reaching network of anti-Dominion separatists, and stationed elite espionage agents throughout the Koprulu sector to keep tabs on the Dominion.[3]

Mengsk's ambitions included bringing both Umoja and Moria back into the Dominion fold.[8] The Dominion imposed an economic blockade on the Protectorate, forcing the Protectorate to smuggle food to their own people. As the Protectorate negotiated the tariffs with the Dominion, it also broadcast holos to the Dominion, and planned on using the infamous Michael Liberty to do the reporting for them.[9]

When the Dominion revealed that one of its senators, Corbin Phash, had hidden the psychic talents of his son Colin, the family separated and hid from the Dominion. Corbin traveled to the Protectorate and struck an alliance with Minister Jorgensen while Colin took shelter on a refugee world. However, Colin was captured and taken to the Ghost Academy, prompting Corbin to vow to expose the truth behind the Academy. Jorgensen promised to help, suggesting he knew Dominion media figures such as Kate Lockwell.[10] Corbin's presence was a thorn in the side of the Dominion, and a ghost was dispatched to assassinate him. It failed. The Umojans did not retaliate however, only taking further steps to protect Phash.[9]

Umoja continued to compete with the Dominion over control and resources,[11] all the while preparing for war with Arcturus Mengsk or the zerg.[12] The Umojans would eventually spread anti-Ghost Academy propaganda to dozens of Dominion worlds.[13] Eventually Corbin Phash would arrange for his son to be freed from the Academy, and he would be trained as a shadowguard.[6]

By 2503,[14] Protectorate agents were the first to investigate the Thor project.[15]

By that year, the Protectorate hatched a plot with Project Shadowblade, led by General Cole Bennett and Gabriel Tosh, which would use a unique AI and spectres to capture Mengsk, and force him to confess to his crimes in front of renegade reporter Michael Liberty. However, the plot was foiled, and the spectre's base of Gehenna Station was destroyed by Agent Nova Terra and the Annihilators, ending their rebellion.[6]

The Second Great War[]

With the zerg invasion of terran space in 2504, the Protectorate mobilized[16] and closed its borders.[17] In the aftermath of the Flashpoint Conflict, the Protectorate sheltered Valerian Mengsk, Raynor's Raiders, and a de-infested Sarah Kerrigan as they fled the forces of the Terran Dominion.[18]

Research Station EB-103

At Research Station EB-103, Umojan scientists ran tests to find out how much of the zerg mutagen was left in Kerrigan's system.[19] When Dominion forces attacked, Umojan marines held them off while the facility was evacuated.[20] Some Umojan marines ended up on the Hyperion.[21]

The New Dominion[]

After his ascension to the throne Emperor Valerian began making good-faith overtures to the Umojan Ruling Council in the hopes of negotiating a mutual security pact that also included a technology partnership between the Protectorate and the Dominion.[22]

However, under the surface the cold war that had torn a rift between the two nations continued to boil. The Umojans captured documents connecting Emperor Valerian Mengsk to the Moebius Foundation, who bred the hybrid. Valerian suspected they wished to use these to destroy the trust between Valerian and his people. The Umojans kept these documents aboard an impenetrable space fortress named the Keep.

However, the Keep was infiltrated by Agent Nova Terra, who set a freighter on a course for the base disguised as a derelict, with her faking her death inside using a special toxin. Nova was brought inside, and brought in for autopsy when she woke up and began her operation. Nova forced the security of the station to evacuate, planting bombs on the evacuation ships to destroy the sentinel watchtowers surrounding the station. She then broke into the station's vault, retrieved the disks, and escaped before reinforcements arrived.

Later, in an effort of goodwill and to ensure that such secrets never damage the trust he had with his people, Valerian Mengsk made the documents public to the Terran Dominion.[23]

Jarban Minor[]

Umojan terrazine mining operations on Jarban Minor

The Umojan Protectorate sent an expedition to the planet of Jarban Minor, and began setting up extraction devices to harvest the terrazine from the native Jarban gliders. They also began mining the local crystal formations, and set up a science facility to research the planet. However, the Umojans came under attack by the zerg, and most of their research team became infested.

During the Defenders of Man Insurgency, Terran Dominion Agent Nova Terra and her Covert Ops Crew to the planet under the guidance of Tal'darim Highlord Alarak in order to obtain terrazine. They rescued the surviving Umojans, fought through the infested and Tal'darim under First Ascendant Ji'nara, harvested the terrazine, and escaped the planet.[24] UNN later reported on the rescued Umojan research team.[25]

Securing the Borders[]

"The zerg are a potential threat. The Dominion is a definite threat. Perhaps not as great as when Arcturus Mengsk was emperor, but whether or not you have territorial ambitions, the fact remains that many in your government still want to see the Umojan Protectorate as part of the Dominion."

- Envoy Louise DuPre(src)

By 2511, the Umojan Protectorate had some of the most advanced biotechnology in the sector, and made efforts to secure its borders against any future zerg or Dominion attack. In the case of an outbreak of infestation on their southern border, the Umojans were counting on aid from the Daelaam for its defense. Envoy Louise DuPre was sent to the Dominion to continue peace talks with Emperor Valerian Mengsk, but was skeptical of the Dominion as a continuing and real threat given all the Protectorate suffered from Arcturus's ambitions. The Dominion meanwhile was undergoing a series of droughts and famines, and requested Umojan biotechnology to aid them in return for stationing forces on their southern border to defend against a resurgent zerg swarm, but this request was denied as the Umojans remained convinced there were still many within the Dominion government who wanted to see the Protectorate as part of the Dominion.[26]

Improvements made to the armor of Umojan marines have led to suggestions that the Protectorate is preparing for a future conflict.[27] The Umojans did not recognize the treaty between the Terran Dominion and xenos powers, and prepared many of their factories for a potential war with them, though some speculated the weapons were more for use against terran powers.[28]

However, research was done in to weapons specifically to combat the protoss.[29] Such research caught the eye of a renegade Nerazim, who raided one their secret lab at Spearpoint Base on Aeneas, and stole their weapon, then leading the Tal'darim and their Death Fleet to the base. At the Fall of Spearpoint Base, the Tal'darim annihilated the Umojan defenders and destroyed the base, though early warning allowed the Umojans to evacuate much of the base's civilian population.[30]

Around the time of the Battle of Camp Pitcairn, the Umojan Protectorate began making territory grabs, forcing the Dominion to deploy their forces to counteract their movements.[31]

Government and Society[]

Umojan Protectorate insignia

The worlds that claim allegiance to the Umojan Protectorate have long held independence as their defining trait.[32] Umojans are fiercely independent[1] and consider themselves to be an enlightened people, harboring obvious contempt for their sister colonies that submitted to the near-fascist yoke of the Terran Confederacy.[2] Subsequently, Umojans defied the espoused right of Emperor Arcturus Mengsk to rule over all terrans, and the Protectorate took great pains to ensure its way of life wasn't compromised by the Dominion.[32]

Umojan architecture and technology is known for being highly functional,[1] and the technology has a reputation for being cutting-edge. The Umojans are known for possessing a small government and lucrative economy,[33] said government being run by the Umojan Ruling Council.[4] Umojan technology is sought after by the Terran Dominion, and is considered to be a rarity even among their most advance technological circles.[24] Many workers from around the sector seek jobs in Umojan factories as a chance to start a new life, as they have a reputation for good pay and high security.[28]

The Protectorate seeks a truce with the protoss, believing that the elder race can teach them the mysteries of the greater meaning of life, the universe, and everything.[2] However, the Protectorate is unable to decode the protoss's Khala-based communications, and the protoss have ignored them.[34] By 2511, the Umojans relied on defense from the Daelaam against any future zerg incursions, though Valerian Mengsk questioned whether or not aid would actually be provided.[26] In spite of their love of the protoss, the Protectorate never signed the ceasefire between the three races, and stockpiles arms in the case of a xenos attack, though many suspect this is just as much a precaution against the Dominion.[28] Secretly, the Protectorate even has worked on experimental weapons specifically to combat the protoss.[29]

Compared to other major factions, the Protectorate is underpowered and under-resourced, with a smaller population, but it leverages its great technology to stay afloat,[35] said technology being the envy of the Dominion Armed Forces.[36] Its military forces have regularly been noted to be more advanced than their counterparts from other terran factions. Umojan engineers are fond of robotics, and have demonstrated willingness to develop artificial intelligence that would be considered unsafe by their Dominion counterparts.[27]

The Protectorate may have a reputation for extremely effective methods of collecting information,[4] utilizing agents such as shadowguards to retrieve it.[15] The Protectorate was especially cautious about safeguarding its scientific (research) endeavors from the Dominion. In the Protectorate, hidden laboratories and plausible deniability aren't options - they're standards.[32] Through various (sometimes illicit) means, the Protectorate has managed to obtain a variety of Dominion ground and aerospace units and incorporated them into its own arsenal.[27]

Umojan marines

The Protectorate also maintains standard forces such as marines,[32] and by the post-Guild Wars era their marines wore pale blue powered armor.[1] By the Second Great War, they were equipped with their own type of armor,[37][38] as opposed to the standard CMC design of past years.[9] Umojan soldiers have a longer average lifespan compared to their counterparts from other terran bodies, a figure which has been attributed to the extensive medical training of their medivac pilots.

During the Great War, the Protectorate's militia color was aqua.[2]
