Earth Empire The Earth Empire was formed sometime between 2480 and 2520 and fell sometime between 2980 and 3020 . History . The definitive date of the formation of the Empire remains unknown . Around 2501 , Earth was controlled by EarthGov . ( PROSE : " The Monsters Inside " ) In the 2530s , an Earth Federation existed . ( PROSE : " The Colony of Lies " ) By 2472 , Earth was severely polluted and overpopulated , with a hundred billion citizens . ( TV : " Colony in Space " ) In 2480 , Earth was invaded by the Korven , leading to a human victory . Tensions between the Earth Empire and the Korven lasted until at least 2618 . ( TV : " The Korven " ) In the 26th century , human s occupied one part of the Milky Way galaxy , while the Draconian Empire occupied another . There was a war between the two after a cultural misunderstanding ( humans being unaware that Draconians sent battlecruisers to diplomatic meetings ) , ending with articles of peace that guaranteed a " frontier in space " between the two ; trade agreements and cultural exchanges were instituted to lessen tensions . ( TV : " Frontier in Space " ) Food was imported from the colonies . Cities like New Glasgow and New Montreal were built in the Arctic , and population control laws restricted families to one child unless they moved to the Arctic cities . A free press and broadcasting service existed . ( TV : " Frontier in Space " ) The Earth Empire continued to grow and established Skybase s as command centres wherever Earth had a presence . ( TV : " The Mutants " , PROSE : " Cold Fusion " ) In a later presidential election , war hero John Williams campaigned for an " aggressive inter - stellar policy " against the successful candidate . She appointed him to her government to heal political divides . ( PROSE : " Doctor Who and the Space War " ) In 2540 , , employing Ogron s , stirred up war between Earth and Draconia on behalf of the Dalek s . Faked attacks on frontier craft had the human public and political opposition soon demanding war . His plan was exposed ( TV : " Frontier in Space " ) and the Second Dalek War began . ( PROSE : " Return of the Living Dad " ) It would rage on for decades , with an entire " Dalek Generation " who couldn ' t remember peacetime . ( PROSE : " Prisoner of the Daleks " ) Mars itself was occupied . ( PROSE : " Beige Planet Mars " ) Not every human in space chose to live in the Earth Empire . One band of the anarchist Travellers , for example , settled on Heaven , a neutral planet used as a burial ground by both sides . ( PROSE : " Love and War " ) Some time after the 26th century , the Earth Empire invaded Tractis and enslaved the Tractite s . ( PROSE : " Genocide " ) A Third Dalek War would put a stop to the Empire ' s expansion for a while . ( PROSE : " The Chase " , " Sky Pirates ! " ) In later centuries , the Empire became increasingly more unequal , prejudiced , and under the control of a Divine Empress . ( PROSE : " Secret of the Black Planet " , " Original Sin " ) In the 28th century , townships around the major cities were no - go areas and travel permits were required to leave them ; Earth was divided into regions ( including the moon ) and administered by a president , with Africa , South Chinese Union , and the moon as the wealthiest ; and the IT corporation Panafrica , run by the mighty Rohihlahla family , had rewritten history to portray Nelson Mandela as the founder of apartheid , to support the contemporary African elites and their apartheid policies . The Rohihlahlas ' machinations were exposed and the dynasty is supplanted by the Forresters . ( PROSE : " Secret of the Black Planet " ) Also in the 28th century , the Empire came to Sense Sphere to exploit its mineral wealth . Two humans deserted the Sense Sphere in their spaceship while pretending to get reinforcements , but their Commander blew up the ship , leaving three humans stranded for ten years as they slowly poisoned the Sensorites from the aqueduct s . When more humans came , the Sensorites held them hostage until the First Doctor and his companions made peace . ( TV : " The Sensorites " ) In 2850 , a new Empress was crowned . ( PROSE : " So Vile a Sin " ) By the mid - 30th century , an aged Divine Empress reigned from her Imperial Palace in orbit around Saturn , with a feudal system in place . The empire was conquering alien planets and most imperial subjects were prejudiced against other species , even though humans , by this time had learned to " body bepple " into new , sometimes alien - seeming forms . Earth Reptile s had the highest status among non - human species , as they were Earthborn . The rich lived in hovering Overcities , leaving the poor and alien on the polluted surface of the Earth , with the decaying former cities like London ; even the Overcities were stratified by wealth , with the relatively poorer confined to lower levels . The Imperial Landsknechte and the " Vigilant " space defences had Earth defended . ( PROSE : " Original Sin " , " So Vile a Sin " ) Environmental devastation had left Earth in a degraded state . On conquered alien worlds , human " Overlords " ruled aliens , who had lesser rights , from Skybase s . ( TV : " The Mutants " ) In 2957 , the Earth Empire had recently fought the latest of the Wars of Acquisition . This had included the Empire terraforming the Hith homeworld and leaving the species homeless , as well as Earth itself being bombarded . Icaron radiation from a Hithis ship held by Tobias Vaughn sparked off a wave of psychotic murders which escalated to Overcity riots and some cities falling from the sky . ( PROSE : " Original Sin " ) This started the Empire ' s downfall . In the late 30th century , the Empire had begun to crumble : with Earth exhausted politically and economically , it could not afford an Empire and began giving independence to its colonies . ( TV : " The Mutants " Attempts were made to check the fall of the Empire , with little success . ( PROSE : " The Sorcerer ' s Apprentice " ) In 2982 , as a war with the Ogrons dragged on and political factions vied for power , the Seventh Doctor and his companion , the Adjudicators Roz Forrester and Chris Cwej got involved in a political struggle which would end in the installation of Roz ' s sister , Leabie , as the new Empress . The current Empress was centuries old and her mind was slaved to the computer intelligence Centcomp , which effectively ran her Empire , and requested the Doctor kill her . ( PROSE : " So Vile a Sin " ) Within five years of becoming Empress , Leabie Forrester dismantled the Empire , granting independence to every planet whether they wanted it or not . After which , Earth was abandoned by its former colonies as the Overcities fell out of the sky , and the remaining population descended into barbarism , with the surviving humans turning on the aliens as sources of food . ( PROSE : " Dependence Day " ) Its collapse left a power vacuum that , by the 34th century , would be filled by the Earth Alliance , a more loose alliance of Earth and its colonies ( AUDIO : " The Sirens of Time " , " Invasion of the Daleks " ) , and the Galactic Federation , which would be less Earth - centric and human - dominated ( PROSE : " The Dark Path " ) A Terran Federation also existed by the late 29th century . ( AUDIO : " Occam ' s Razor " ) On Earth itself , humanity would rebound in the later 31st century . Survivors of the Overcities would form Europa in former Europe ( PROSE : " Managra " ) and the Fifth Doctor said the 31st century was " all space cities and monorails . " ( AUDIO : " The Butcher of Brisbane " ) The planet would become a founding member of the Federation in the 32nd century . ( PROSE : " Legacy " ) The Galactic Federation would last to at least the 41st century , upon which it was fatally damaged in a war with the Daleks ( PROSE : " Legacy " ) , and the Earth Alliance to at least the 41st century until its own Dalek war . ( AUDIO : " Invasion of the Daleks " ) An Earth - centred humanity was already quite powerful in 4000 ( TV : " The Daleks ' Master Plan " ) and would evolve into the Earth Empire ' s successor , the Second Great and Bountiful Human Empire . ( TV : " Planet of the Ood " ) Undated events . Ron Cordell almost started a war in the Earth Empire when he hired Skink s to blockade the important trading planet Vourakis 3 . The Twelfth Doctor and " Transmetropolitan " reporter Heddy Garber went onto the Skink ship and destroyed it , averting the war and killing Cordell , who was on the ship at the time . ( COMIC : " Pirates of Vourakis " ) Technology . Empire ships were generally built of spheres , connected by scaffolding . Ships were covered with bas - relief carvings of leaves and faces and similar decorations . The designs used by the Earth Empire were considered unpleasant by other species . ( PROSE : " The Dark Path " ) A specific type of ship was the Dauntless - class Imperial Destroyer . ( PROSE : " The Dark Path " ) The citizens of the Empire ( and others ) used puterspace , a form of virtual reality . ( PROSE : " Love and War " ) The Empire ' s monopoly on null - grav technology kept it powerful . ( PROSE : " Original Sin " ) In the 30th century , body bepple s allowed Earth Empire citizens to alter their bodies so that they barely resembled humans . ( PROSE : " Original Sin " ) Political system . The Earth Empire was a lumbering bureaucracy with as many civil servants as civilians . The planetary or colonial governor of a planet was called a Viscount . ( PROSE : " The Dark Path " ) In the 26th century it was overseen by a President of Earth , who headed a world government with a Cabinet , a congress , and a senate ; a democratic opposition existed within the congress and senate . The government also had a Bureau of Population Control . An outlaw political group , the Peace Party , tried to gain power . ( TV : " Frontier in Space " ) As with the British Empire , dominion planets like Sirius IV had a large degree of autonomy . Some on Earth looked down on the dominions as jumped - up colonies . ( TV : " Frontier in Space " ) Eventually , the Empire would be run by a Divine Empress with absolute control . ( PROSE : " Original Sin " ) The 30th centuy had a feudal system : Barons controlled a few hundred levels of an Overcity , a Viscount ran an Overcity , a Count or Countess ruled about ten Overcities , a Marquess or Marquessa ruled Earth , and the Duke Marmion controlled Earth ' s Solar System . ( PROSE : " Original Sin " , " So Vile a Sin " ) There also existed an Earth Reptile Economic Confederation in the 30th century . ( PROSE : " So Vile a Sin " ) The Folflower System was unusual in its constitutional monarchy for most of the duration of the Empire . ( PROSE : " The Graves of Mordane " ) Military forces . In purely military matters , the President ' s power was limited ; to overrule the head of the military in these matters , the President needed the backing of the full Senate . ( TV : " Frontier in Space " ) The Empire had the Spacefleet ( PROSE : " Deceit " ) and an Imperial Navy ( PROSE : " The Dark Path " ) . Security was provided by the Imperial Landsknechte or Naval Troops . ( PROSE : " The Dark Path " ) They also had a feared Earth Security organisation that interrogated suspected traitors , often using mind probe s . A Special Security Act allowed the President to deport traitors to the Lunar Penal Colony without trial . ( TV : " Frontier in Space " ) In 2540 , some of the senior military officials believed a military dictatorship would lead to a more effective and stronger Empire . General John Williams did not agree but was willing to use the threat of these officials to pressure the President . ( TV : " Frontier in Space " ) In 2618 , the military force of Earth was the Global Command . One of the divisions of Global Command was the Special Operations Commando . ( TV : " The Korven " ) In later centuries , the Empire ' s forces would begin to conquer alien races and inhabited worlds . ( PROSE : " Original Sin " ) In 2982 , the special army / religious order Unitatus was part of Earth ' s defences . ( PROSE : " So Vile a Sin " ) Crime and punishment . In the 25th century , the Adjudicators Bureau settled legal disputes in the Empire and enforced Earth law . ( TV : " Colony in Space " ) In the 26th century , Interplanetary Police Commissioners administered off - planet law , using their own ships with cell facilities . ( TV : " Frontier in Space " ) During war , condemned criminals were given the choice to be sent into Dalek space as Dalek Killer s , essentially a suicide mission , rather than execution . ( COMIC : " Abslom Daak . . . Dalek Killer " ) Under the Special Security Act , political dissidents went to the Lunar Penal Colony ( TV : " Frontier in Space " , PROSE : " Love and War " ) , Justicia ( PROSE : " The Monsters Inside " ) or Draconian Penal Colonies ( PROSE : " The Dark Path " ) . The Lunar colony was a life sentence . Many of the dissidents were members of the Peace Party . One Peace Party member remarked to the Doctor that you could be arrested merely for criticising the government . Hardened criminals from regular prisoners were hired as trustees at the Lunar Penal Colony . ( TV : " Frontier in Space " ) In the later years of the Empire , the Adjudicators ( now the Guild of Adjudicators ) would become an armed law enforcement body . ( PROSE : " The Dark Path " ) Territories . Colonies under Earth control included : In the 25th century , planets were tasked for either colonisation or mining . ( TV : " Colony in Space " ) There were often tensions with the colony worlds , even into the 26th century . ( TV : " Frontier in Space " ) Some of these planets , such as Sirius IV , had status , allowing them to tax and try their own citizens . Many on Earth looked down on them , seeing them as still colonies . ( TV : " Frontier in Space " ) The Empire would capture and subjugate many inhabited planets and their indigenous populations . ( PROSE : " Original Sin " ) ( PROSE : " So Vile a Sin " ) An apartheid system would exist on some of these planets , including Solos . ( TV : " The Mutants " ) In the 30th century , the Empire began to collapse . Many colonies were given independence . ( TV : " The Mutants " ) Notable individuals . As noted previously , the Adjudicators Chris Cwej and Roz Forrester of the powerful Forrester family grew up in the late Earth Empire period of the 30th century . ( PROSE : " Original Sin " ) Two other , very different 26th century individuals , both of whom had loved ones killed by the Daleks ( and who later met ( COMIC : " Emperor of the Daleks " ) ) lived during the earlier history of the Empire : Though originally native to the late 1980s , after her travels with the Seventh Doctor , Ace decided to stay on Heaven at the same time as Benny joined him . ( PROSE : " Love and War " ) Ace joined Spacefleet , where she served for at least three years in her mid - to - late twenties . ( PROSE : " Deceit " )
