The Kree Empire is a major galactic government founded and ruled by the Kree, a scientifically and technologically advanced species from the planet Hala. Possessing very few rival entities, the Kree Empire is one of the most powerful states in the galaxy.

- "If the Kree Empire learned that these experiments were a success, they would try to duplicate them."
During one of their wars, the Kree Empire experimented on species on different planets in order to create slave-soldiers to help them in their war. While most of these experiments failed, they succeded on the planet Earth.
A rivalry developed between the Kree Empire and the Nova Empire of Xandar, to the extent that a war occurred between the races. The war raged for a thousand years before hostilities were finally ceased. A peace treaty was in place by 2014. Old hatreds continued to run deep however: rioting broke out across the Kree Empire when the treaty was signed, and one official, Ronan the Accuser, was so consumed by his hatred of the Nova Empire and the Xandarians in particular that he made a pact with Thanos, in order to exterminate the world.
Nova-Prime Irani Rael called the Kree Ambassador, requesting assistance against Ronan, or at the very least, a statement condemning the murderous actions of the wayward Accuser, who was technically acting in violation of Kree law. The Ambassador ignored the request. 
A Kree named Vin-Tak came to Earth after receiving a signal that a Diviner had been activated; he wanted to make sure that the Kree Empire did not know that the ancient experiment of Terrigenesis performed on Humans millennia ago was successful.
