The datation for the early stages of the Empire varies, with events seemingly inconciliable, possibly due to errors or retcons.
In the Kree Year Zero, about a million years ago,[verification needed] the Kree had their first encounter with the Skrulls. The meeting went disastrously and the long and bitter war started between the two races. The Kree eventually spread throughout the galaxy, establishing a vast empire.
The Kree launched an attack upon the Skrull Empire and the peaceful Skrulls were forced to return to their warlike tendencies to defend themselves. The Kree-Skrull War would continue for hundreds of thousands of years.
At the same time, the Cotati on Hala were almost driven to extinction by the Kree. However, a small handful of Kree, the pacifist Priests of Pama, hid and kept safe a group of Cotati. Eventually these Kree began worshiping the Cotati that they had kept sheltered. To further hide and keep them safe, the priests relocated the surviving Cotati throughout the universe.
About 250 years later, the Kree Science Council, aware that the Skrulls had once created an incredibly powerful weapon called the Cosmic Cube, designed a cybernetic/organic supercomputer called the Supreme Intelligence (sometimes referred to by the honorific "Supremor") to help them in creating a Cube. When the computer became functional, it determined that a Cosmic Cube would be too dangerous to construct and refused the Science Council's request. The computer was then used simply in an advisory capacity.
Over time, and as the war with the Skrull dragged on, the Supreme Intelligence gradually accrued more and more political power and responsibility until finally it was elected as absolute ruler of the Kree. Eventually, the Supreme Intelligence came to be worshiped and an organized religion built up around.
Activities in prehistoric Earth's solar system
They established a station on the planet Uranus, a strategic position between the Kree and Skrull Empires. Through their work at this station, they discovered that sentient life on nearby Earth had genetic potential, invested in it by the alien Celestials. Intrigued, the Kree began to experiment on Earth's pre-humans.
Experimenting on Earthlings
The Inhumans' Creation
Around 25.000 years ago, The Kree travelled to Earth to investigate possible ways of circumventing their own evolutionary stagnation, and to create a powerful race of soldiers for use against the Skrulls. The Kree (along with a Sentry) came to a tribe of Neanderthals and experimented on them, because of their genetic potential for manipulation, which was discovered due to the Kree dissecting Arlok, a fallen-in-combat Eternal, and finding out the Celestials' experiments on the early humans.
Those Kree experiments lasted for twenty-five years, and led to the creations of an off-shot who would eventually be known as the Inhumans, their divergence from humanity occurring twenty-five thousands years ago. However, although their experiments were successful in creating a strain of humanity with extraordinary and diverse abilities, the Kree abandoned their experiment for reasons which are not yet clear. 
Kree dormant evolution
4th century BC
Along with other Kree Eternals, Ard-Con journeyed through space and traveled to Earth 4000 years ago. After being mistaken for Gods by the Celts, all Kree Eternals soon left, save for Ard-Con who lived there for a millennium, but was soon imprisoned by Tantalus.
2nd century BC
In 200 B.C. A great Greek inventor, Archimedes utilized his intellect to build the Colossus of Rhodes, a massive mechanical construct with which he defended Rhodes against a Kree Sentry, defeating the Sentry, but at the cost of the Colossus of Rhodes.
The Fantastic Four's unwary awakening of the long-dormant Sentry, alerted the Kree to Earth's advanced state of evolution. The Sentry's destruction brought the Kree official Ronan the Accuser, with the intent of passing judgment on those who "murdered" the outpost guard; his own defeat increased Kree scrutiny of Earth.
The Supreme Intelligence sent a group of soldiers on a secret mission to Earth commanded Yon-Rogg. Mar-Vell was sent undercover to infiltrate human society. He took the identity of Dr. Walter Lawson a recently deceased N.A.S.A. scientist. Yon-Rogg was jealous of Mar-Vell and Una and tried to kill him while on Earth.
The Earth's importance as a strategic beachhead became apparent when the Avengers became involved in the latest round of Kree-Skrull hostilities. The Skrull were revealed to have been infiltrating human society in an effort to control America's political infrastructure, using their shape-shifting abilities to replace key political figures. In the meantime, the Kree were reestablishing cultural ties with the Inhumans, ostensibly for the purpose of technological exchange, although their true intentions turned out to be far more sinister.
At this point, Captain Marvel, former hero of the Kree Empire, approached the Avengers with evidence that renegade elements within the Kree Hierarchy (led by Ronan the Accuser) were planning to 'erase' humanity through the use of exotic technology. This particular scheme was foiled by Marvel and the Avengers (comprised, at that time, of Goliath, Quicksilver, the Scarlet Witch, the Vision, Yellowjacket, the Wasp, and eternal side-kick Rick Jones) but it proved to be only the tip of the iceberg.
As the war escalated and Earth's position became increasingly precarious, the original Avengers (including Thor, Iron Man and Captain America) were recalled to active service after a Skrull scouting party (led by interstellar menace the Super-Skrull) managed to abduct Marvel, Quicksilver and the Scarlet Witch. The Skrull also attempted to destroy the Inhumans' Great Refuge with a nuclear-level incendiary device, but failed when the Avengers intervened. This was the group's first inkling that an interplanetary war was being fought over possession of the Earth. During the ensuing conflict, the Skrull took his prisoners back to the Skrull homeworld, leaving the remaining Avengers to pick up the pieces and reform their tattered forces.
The conflict worsened when the Avengers began to understand the scale of the war erupting all around them. Setting off in pursuit of their kidnapped allies, they discovered a vast 'Skrull' armada en route to devastate the planet Earth; an equivalent Kree fleet poised to annihilate the Skrulls; and a full-scale insurrection breaking out between the Supreme Intelligence and Ronan the Accuser. All sides were determined to either invade or decimate the Earth in order to prevent it falling into the 'wrong' hands. Led by Thor, Iron Man and the Vision, the Avengers launched an attack on the Skrull flagship, somehow managing to turn back the fleet after a desperate battle (during which Goliath was deemed to be MIA and presumed dead).
The war came to a close when the Supreme Intelligence managed to bring Rick Jones into his presence. The Supreme Intelligence had been usurped by Ronan the Accuser, but (as he explained to Rick in retrospect), he was still capable of channelling his powers through an agent. While the Supreme Intelligence cared little for the fate of Earth and its inhabitants, he recognized that the Kree-Skrull war was futile, and temporarily altered Rick's DNA to release his 'full evolutionary potential.' Armed with godlike powers, Rick literally froze both Kree and Skrull forces in mid-stride, allowing the Supreme Intelligence to re-establish control over his people and bring the war to a halt.The effort proved too much for Rick's fragile human physiology; as he collapsed lifeless to the floor, the Supreme Intelligence teleported the remaining Avengers to his side to witness his grim sacrifice. The irony was not lost on the assembled heroes, who reflected that a frail teenaged boy had succeeded where all of their collective might had failed. The final act in the cosmic tragedy was played out by Captain Marvel, who - understanding the debt owed by all of them - agreed to merge his life-force with Rick's body, bringing the boy back from the brink of death at the cost of his own existence.
New Kree-Skrull War
At several points in the years after the end of the first Kree-Skrull War hostilities were said to have broken out again between the two empires. It is unclear how serious these conflicts were though they were often referred to as "wars". The most significant of these instances came when the Skrulls lost their ability to shapeshift, and a Skrull Warlord provoked new hostilities. During this war, the Supreme Intelligence was incapacitated by the Silver Surfer who removed the Soul Gem which the creature used to maintain peaceful balance between its blue and pink Kree components. Afterwards, Nenora, a Skrull spy in the guise of a high ranking Kree official, took command of the Kree empire. The war ended with Nenora being exposed as a Skrull. Leadership of the Kree was assumed for a time by an alien named Clumsy Foulup. Another significant conflict arose during the Infinity Gauntlet event when the machinations of Thanos led to the sudden elimination of half the universes lifeforms. Unaware of Thanos' role in the disappearance, the Kree and the Skrull blamed each other and temporarily renewed fighting.
Not long after the conflicts with the Skrull ended, the Kree again found themselves embroiled in a war, this time with the Shi'ar Empire. This war was much shorter, and was engineered by the Skrull and the Supreme Intelligence. The Avengers of Earth became involved in the conflict and their involvement (primarily between the Vision and Wonder Man) inadvertently set off a chain of events which led to a Nega-Bomb being detonated in Kree space. The bomb explosion, in which negative energy was released into space causing an extremely powerful explosive and radioactive reaction, devastating the Kree empire and killing ninety eight percent of the entire Kree population. This act of extreme genocide led to the Kree's surrender to the Shi'ar. The Supreme Intelligence was eventually revealed as being ultimately responsible for the bomb's detonation, the whole thing being a bid to kickstart the Kree race's genetic development.
A Kree territory was then annexed by the Shi'ar, with Majestrix Lilandra naming her sister Deathbird as the territory's administrator. Deathbird has since abandoned this post and it appears that the Kree Empire has, at least in some part, been re-established as they again had larger numbers and a feared Army.
Ruul and Return of the Empire
The Kree have since returned to their prior form. The general consensus, explained by Elysius is that when Captain Marvel convinced Entropy (son of Eternity) to destroy the universe, but then to recreate it almost exactly alike albeit with Entropy having become Eternity, it caused some 'discrepancies' (such as Genis-Vell's mother being still alive, and having a grownup daughter) and that some of these 'discrepancies' seemingly rippled back across time and showed up before the reconstruction of the universe, including the Kree again being an influential Empire and no longer appearing as the Ruul.
Destruction of Hala
With the resurgence of the Black Vortex, a powerful item capable of unleashing the cosmic potential of whoever used it, the Kree attempted to destroy it. The Supreme Intelligence sent Ronan and the Accuser Corps to take it from their current possessors, the cosmically enhanced Gamora, Beast, and Angel.
In retaliation, the three cosmically-enhanced beings assaulted Hala. The Accuser Corps tried to fight off their attackers, but were notably overpowered. After being denied by the Supreme Intelligence to use the power of the Black Vortex to fight back, Ronan the Accuser disobeyed him, and submitted to its power, ensuring a successful defense for the Kree homeworld, and forcing Gamora, Beast, and Angel to flee after the latter was knocked down.
Once the dust settled, the Kree attempted to get rid of the Black Vortex once more. However, they were attacked by Mister Knife and the Slaughter Lords, another party interested in the Vortex. Taking advantage of the state of frailty in which Hala was left, he used all the firepower of his flying fortress to destroy the planet. The Supreme Intelligence demanded his Accuser Corps to escape, while he remained in Hala and perished.
Thanks to the power of a cosmic artifact known as the Black Vortex; Ronan, one of the last living Accuser's. Was last seen alive within the decimated remains of the destroyed Kree home planet, wallowing in bitterness and despair over the destruction of his protectorate charge. He would beset the royal envoy of Inhuman space farers led by Marvel Boy; whom sought to reinvigorate the empire via a Plex Intelligence seedling while on their jaunt through the cosmos.
Ronan still bore inherent resentments of Crystal and the Royal family due to having left the dominion, more importantly; of Her having left him behind.
But after they all had escaped his judgement, placated by cosmically simulated Pocket Battlefield techniques, Noh-Varr initiated a Supremor regenesis via implementing a seedling of his old Plex command module in an attempt to revitalize the Kree Empire as a pacifistic enterprise instead of it's warmongering predecessor.
Death of the Inhumans
An outlier of Kree explorers would return to the remains of their shattered realm, horrified to learn that a band of Brigands led by a disgraced king turned criminal mastermind hand destroyed it. Masterminding an ultimate plan to revitalize their shattered fiefdom, these remnants would depose of Ronana and subject him to inhumane cybernetics experimentation; rechristening themselves as the Kree Imperium.
They would seek to deploy a monstrous super-inhuman carrying all the powers of it's adjacent race by the name of Vox to attack and slaughter any/all the Inhuman's across the galaxy whom would not join their cause willingly.
As Black Bolt refused to aid these loathsome individuals whom committed atrocities against his subjects in preparation for war against Earth and its Inhuman Population. Vox had the Inhuman King crippled by slitting his throat. But the Midnight King would escape his confines and slaughter his would be slave master while giving the desecrated Ronan an honorable end with his voice. Blackagar would find rescue at the hand of his family with aid from Lockjaw's friend; Beta Ray Bill.
The lot are horrified to discover that there is no super-inhuman, but a whole enclave of bionically modified inhumans enslaved by the heretical Imperium to do their bidding.
The Inhuman royal family would set out to do final battle with their tormentors only to be met by a brainwashed Crystal & Lockjaw. Black Bolt would use the last of his energy to decimate the Inhuman army. Putting an end to the Kree's threat for a time.
An Kree Army officer and his crew once prayed to the "Gods of Pama". The prayer ended this way: "...and consign you to the gods of Pama, for your having died valiantly in battle... a death that the Kree appreciate above anything else. So say we all".
