HISTORY / IMPORTANT EVENTS - page 1
Kreekind began untold eons ago on the planet Hala, in the satellite galaxy humans have named the Greater Magellanic Cloud. The prehistoric ancestors of the Kree were visited by the enigmatic and vastly powerful aliens called the Progenitors, the first in a series of extra-terrestrial interferences that would set the Kree on a path to galactic empire.
Using the substance known as primagen, a mysterious mineral that enhances genetics, the Progenitors forcefully evolved the Kree. The Progenitors mission was to find genetic stock worthy of upgrading into new members of their species. As the super-advanced geneticists never returned to claim the Kree, presumably they never met the Progenitor’s standards. [Royals #9, Inhumans: Judgement Day #1]
However, the Progenitors were not the only godlike aliens to experiment on the Kree. The Celestials, a race of godlike being that had experimented on humans, Skrulls and many other 
species, also came to the Kree. As with their experiments on other species, the Celestial created powerful subspecies of Kreekind. While only the Kree Eternal subspecies has been seen, the history of other species on which the Celestials had experimented suggests Kree Deviants also existed at some point.
Over time, Kree civilization evolved to an Iron Age equivalent. A barbaric, carnivorous people, the Kree hunted large game for food and the strongest warriors led their tribes. By happenstance, the Kree were not the only intelligent species to evolve on their planet. They also shared it with the sentient plant species known as the Cotati. While the warlike Kree hunters and the peaceful, insular Cotati had little reason to interact, they were thrust together when their world was visited by visitors from not only another world but another galaxy - a species of shape-shifting aliens known as the Skrulls.
The Skrulls came offering technology and knowledge in exchange for fealty. However, they wished only to deal with one species and determined a test would decide. Representatives from each of Hala’s two species were transported to a different world and left for a year to construct something that would be judged by the Skrulls on their return. The members of the Kree party 
were left on the blue area of Earth’s moon, a section enclosed in a breathable atmosphere, where they toiled for a year to create a magnificent city.
The Kree were immensely proud of their works but, upon being returned to Hala from the judgement, they were incensed at the rumors that the Cotati, who had grown beautiful garden for their test, had impressed the Skrulls more. Not willing to wait for the outcome, the Kree slaughtered the Cotati, then killed the Skrulls and claimed their technology for themselves. Within ten years, the Kree had amassed an armada of their own and launched an attack on the Skrull homeworld, initiating the Kree-Skrull War. This year, when the Skrulls first arrived and changed the destiny of the Kree, would become Year Zero in the Kree calendar [Avengers (1st series) #133]
Events in the war with the Skrulls took a dramatic turn when the shape-shifters created a cosmic cube, a supremely powerful tool that provided its wielder control over reality. Desperate not to be outdone and unable to create their own cube, the Kree’s top scientists instead created the Supreme Intelligence, also known as Supremor. An organic supercomputer, the Supreme Intelligence was an amalgamation of thousands of the Kree’s top minds, and the Kree hoped it would be able to create the cube where they failed. However, the scientists had created the Intelligence too well and, recognizing the danger a cosmic cube posed, it refused. Eventually the Skrulls lost their cosmic cube after it gained sentience and abandoned its makers. [Captain America Annual (1st series) #7]
The Supreme Intelligence’s knowledge continued to grow, as more minds were added to it, until it eventually replaced the government. Under its leadership, the Kree grew into a star-spanning empire, effectively encompassing the entire galaxy of their homeworld, making the "Kree Empire" and the "Kree Galaxy" almost synonymous. Along the way, the Kree moved their administrative capital from Hala to a planet they named "Kree-Lar.”
Half a millennia after Year Zero, Kree society continued to embrace barbarism and war mongering, to the point that any Kree that favored pacifism were seen as abominations and 
driven into hiding. One group of pacifist Kree were contacted by the last remnants of the Cotati species, in whom they sensed kindred spirits. The Cotati had sprayed seeds after the Kree slaughtered them, and the children from these seeds had hidden away, focusing their energies on evolving their minds. Over the centuries, the Cotati had become immobile and more tree-like. The pacifists tended to the Cotati garden for a time and developed their pacifistic sentiments into a philosophy. They became the Priest of Pama. Unfortunately, they were eventually discovered, rounded up by Kree soldiers and exiled to a barren moon. After a time, the Priests managed to convince the Supreme Intelligence to alter the terms of their exile, allowing them the travel the universe in pairs, helping others. Unbeknownst to Supremor, the Priests used this as a method to transplant the Cotati to worlds all across the universe. [Avengers (1st series) #134]
In largely undisclosed circumstances, a member of the Kree attempted to retrieve the Crystal of Ultimate Vision. As legend tells it, those who pass the Crystal’s test and win the gem would elevate their species to great new levels, while those who fail would doom their species to evolutionary stagnation. The Kree man apparently failed, as many millennia later he was seen frozen, amongst others who had failed the test. [Uncanny X-Men Annual (1st series) #11]
Whether it was the unnamed Kree failing to acquire the Crystal of Ultimate Vision, the genetic manipulations of the Progenitors or Celestials, or standard genetics, the Kree’s evolution began to stagnate. Despite its best efforts, Supremor was unable to resolve the genetic dead-end the Kree had reached.
Twenty-three teams of Kree Xenogeneticists set out on a mass expedition, travelling the universe to discover new genetic stock on which to experiment, with the mission of creating new weapons for the ongoing war with the Skrulls. The scientists visited hundreds of worlds, abducting primitive residents and experimenting on them to study their genetics and create new soldiers. For each of these hundreds of species, the Kree developed a specific catalyst which would trigger their transformation from baseline stock to enhanced variant, in the same way the Progenitors had enhanced primitive Kree with primagen.
About twenty-five thousand years ago, their travels brought them to the Sol system, where the exploratory team came across a vessel near Saturn’s moon Titan, which was transporting human Eternals from Earth. Although the warmongering Kree immediately attacked the ship and destroyed it, they nevertheless managed to retrieve the body of one of the Eternals. The scientists were fascinated by these greatly enhanced humans and believed they had misjudged the primitive humans they had previously dismissed.
With this new knowledge, the Kree scientists returned to Earth and conducted experiments on the more primitive humans, creating the Inhumans with the Terrigen mists. Happy with what they discovered in humanity, the Kree left their new experiments behind, like seeds waiting to germinate. Unbeknownst to the Kree at the time, the destinies of the Kree and their Inhuman creations would be intertwined forevermore. [Inhumanity #1, FF#6, What If? (1st series) #28]
To monitor their experiments, the Kree built a base on Earth, on an island in the South Pacific Ocean, which was guarded by a single, powerful sentry robot. In addition to the monitoring station, the Kree also constructed a citadel within the planet’s Artic Circle with a special purpose. The citadel was fitted with specialized evo-rays, which, when triggered, would revert all life on Earth back to the point the Kree first discovered it – a process known as the “Atavus Plan.” While the exact reason for this is unknown, presumably this was installed in case the Xenogeneticists needed to undo their experiment and start over, since it was set to revert the Earth to the point in time where they first encountered the Inhumans. It is unknown whether the Kree installed other such monitoring stations and Atavus Citadels on the other worlds they created Inhumans. [Fantastic Four (1st series) #64, Avengers (1st series) #90]
Immensely proud of the success of their mass genetic engineering project, the chief Kree Xenoscientist brought their findings to the Supreme Intelligence for review. With intelligence bordering on prescience, the thousands of scientific minds within Supremor were able to identify a flaw within the process; if left unchecked for thousands of years one of the Inhuman tribes the Kree had created would produce a usurper that would kill Supremor. In order to prevent this from ever occurring, the Supreme Intelligence ordered the project to be shut down, the xenoscientists executed and the extermination of all Inhumans on every planet the Kree had created.
Unfortunately, Supremor had made its decision based on incomplete data and, while the Kree Accuser Corps purged hundreds of world, five Inhuman species were missed. These included humans, Alpha Centaurians, Badoon, Kymerians and Dire Wraiths. Thousands of years in the future, this error would prove fateful for Kreekind and the Supremor itself.
As a failsafe, the Supreme Intelligence also created a seed that would recreate itself, should it be killed. It provided this seed to the Supreme Accuser at the time and was stored inside the Accusor’s universal weapon, which was handed down to each successor over the generations until it was needed. [FF (1st series) #6-7]
Meanwhile on Earth, the sentry stationed at the monitoring station continued its preprogramed task of checking in on the development of the Inhumans after a thousand years. During one inspection, it discovered the Inhumans had become far more technologically advanced than the primitive humans and had secluded themselves away in a technologically advanced city, Attilan. The sentry declared that when the Inhumans next met their creators they would be either soldiers or deadly enemies. With no further instructions from its Kree masters, the sentry returned to its base and maintained a period of stasis for thousands of years. [Avengers (1st series) #90]
However, a second Kree sentry, this one several stories tall, visited Earth in the year 226 BC on an undisclosed mission. This massive sentry launched an attack on Rhodes, but was destroyed by the Greek scientist Archimedes, using a robotic Colossus of Rhodes. [S.H.I.E.L.D Infinity #1]
All this time and for thousands of years, the Kree continued their war with the Skrulls, along with the continued, aggressive expansion of their own empire. Supremor brought new species into the empire in the hopes that interbreeding would inject new genetics into the Kree and jumpstart their evolution. This interbreeding resulting in the creation of the pink Kree. While these pink Kree eventually outnumbered the blue Kree, they were considered a lesser race by the “pureblood” blue Kree and were treated as such. [Captain Marvel (1st series) #16]
