Earth Empire

The Earth Empire existed circa the 26th century.

Historical overview
Despite the name, Empire, Earth had a President. (DW: Frontier in Space) The Empire maintained a military force, Spacefleet. (NA: Deceit) In the 26th century, Humans occupied one part of the Milk Way galaxy with the Draconian Empire occupied another part. Circa 2520, tensions between the Empires, and an accident on the part of a Draconians ship, which damaged by a neutron storm, fired accidentally on an Earth Empire battlecruiser, caused the powers to briefly break out into the Human-Draconian War. In 2540, the Master, working for employing Ogrons tried to start up the war, on behalf of the Daleks (DW: Frontier in Space).

Not every Human in space chose to live in the Earth Empire. One band of the anarchist Travellers, for example, settled on the neutral planet called Heaven. (NA: Love and War)

By the 30th century, environmental devastation had ravaged Earth to the point of near-collapse. The Empire had begun to crumble from within. (DW: The Mutants) Though Earth would have other empires, by the 40th century, the Galactic Federation, not so much dominated by that planet and by Humans, would have succeed this one. (NA: Legacy)

Crime and punishment
The Earth Empire sent out Dalek Killers (generally condemned criminals) into Dalek space, essentially on suicide missions. (DWM: Abslom Daak... Dalek Killer) Political dissidents went to the Lunar Penal Colony (DW: Frontier in Space, NA: Love and War). Other criminals went to the prison star system of Justicia. (NDA: The Monsters Inside)

Notable individuals
Bernice Summerfield grew up in this era of history. Also, though originally native to the late 1980s prior to her travels with the Doctor, Ace decided to stay here after abandoning the Doctor. (NA: Love and War) left spent three years living in the Earth Empire after leaving the Doctor. She joined Spacefleet and killed Daleks. (NA: Deceit)

By the mid-26th century Abslom Daak, a particularly savage Dalek Killer who had managed to survive, made a name for himself, so much so that at least one clone existed of him in Human-occupied space (NA: Deceit).

Territories
Colonies under Earth included control included Sirius IV (DW: Frontier in Space), the Althosian system (NA: The Pit) and the Justicia System (NDA: The Monsters Inside). In the 30th century, the Empire also forcibly occupied the planet Solos. (DW: The Mutants)
