Great War ( The Evil of the Daleks ) The Great War was the name used by the Dalek s to identify a series of galactic conflicts fought after the year 4000 which nearly resulted in the extinction of the Dalek race . ( PROSE : " The Evil of the Daleks " ) History . Origin . Dalek expansion . According to Gordon Lowery , Daleks disappeared from human space in the early stages of the 31st century , after an invasion of Earth . Although they stayed clear of human space in the years that followed , the Dalek Empire began a rapid expansion process at the start of the 36th century . In 500 years , they gained control of over 70 planet s in the Ninth Galactic System and 40 more in the Constellation of Miros . ( TV : " Mission to the Unknown " ) Following their failed invasion of Earth in the 22nd century , ( TV : " The Dalek Invasion of Earth " ) the Daleks wanted revenge on the Doctor for his part their defeat . An assassin ation squad was sent from Skaro in a Dalek time machine to hunt down the TARDIS and eliminate the Doctor . Not only did the mission fail but the squad also ended up using all the Dalek Empire ' s supplies of taranium , which the time machine was powered by . The time machine was ultimately stolen and destroyed by Ian Chesterton and Barbara Wright , ( TV : " The Chase " , PROSE : " The Chase " ) crippling the Daleks ' time researches . ( PROSE : " Mission to the Unknown " ) The Daleks gradually rebuilt their taranium supplies but only acquired enough to power their time machines . ( PROSE : " The Mutation of Time " ) In the early 40th century , the Daleks returned to human space and slaughtered a garrison on Alpha Millennia . Six months later , a Dalek ship was sighted near Mars before vanishing again . These were the only records the Space Security Service had on the Daleks later in the century . The Daleks resurfaced again 70 years later with an attack on the Space Exploration Team compound on M5 . Sara Kingdom , Mark Seven and Jason Corey , searching for David Kingdom , discovered the Daleks ' plan to attack Earth again but the Daleks escaped into hiding again . ( AUDIO : " The Destroyers " ) The plot against Earth did not become known throughout the SSS ranks . ( AUDIO : " The Guardian of the Solar System " , TV : " Mission to the Unknown " , " The Daleks ' Master Plan " ) The Galactic Council . In 3950 , the same year he succeeded Amazonia as Guardian of the Solar System , ( PROSE : " Legacy " , AUDIO : " Neverland " ) Mavic Chen commenced a 50 - year mining operation on Uranus to acquire an emm of taranium , intending to replace the Great Clock as a means of protecting the influence of Earth ' s empire . Sara Kingdom , having travelled back in time with the First Doctor , destroyed the Clock in 3999 . Chen thus formed an alliance with the Daleks as part of another plan to protect Earth , ( AUDIO : " The Guardian of the Solar System " ) privately intending to betray them once his ambitions were achieved . ( TV : " The Daleks ' Master Plan " ) Chen and his underling , SSS Security Chief Karlton , became the newest members of the Daleks ' Galactic Council , an alliance of several rulers of the Outer Galaxies all contributing resources to the war force . Other members included Malpha , Beaus , Gearon , Sentreal , Trantis , Warrien , Celation and Zephon , master of the Fifth Galaxy . Meanwhile , as the Daleks plotted in secret , a non - aggression pact was signed in 3975 , bringing about a period of peace and prosperity in the galaxy . This lasted 25 years until the Daleks put their plans to strike at Solar System from Kembel into action . ( TV : " The Daleks ' Master Plan " ) Attempted invasion of the Solar System . In 4000 , the Daleks were at last sighted again in human space . The captain of a space freighter reported a brief sighting of a space vessel which the SSS identified as a Dalek spaceship . Marc Cory , with Gordon Lowery and Jeff Garvey , set off for Kembel , where Cory had a hunch the Daleks were operating . Cory uncovered the existence of the Great Alliance during its first meeting but all three men were killed by Dalek patrols and Varga plant s . Seconds before his death , Cory recorded a message intended to warn Earth of the alliance and the impending attack . ( TV : " Mission to the Unknown " ) Six months later the SSS sent Bret Vyon and Kert Gantry to search for Cory on Kembel as the Council reconvened , with Chen attending for the first time and providing the alliance with his taranium . With the help of the First Doctor , they discovered the Daleks ' plans to use the taranium to power a doomsday weapon called the Time Destructor which could destroy all the planets in the Solar System . The Doctor stole the taranium , leading Chen and the Daleks to pursue him both across the galaxy and through time until it was recovered in ancient Egypt , ( TV : " The Daleks ' Master Plan " ) although the Red Dalek in charge of the time machine was destroyed by the Egyptians who bombarded it with rock s . Yet this would be a small price to pay for the Daleks if their plans succeeded . ( PROSE : " The Mutation of Time " ) Once the Daleks returned the taranium core to Kembel , they broke off the alliance , imprisoning the members of the Council who were still alive . The Doctor , Steven Taylor and Sara Kingdom followed them back to Kembel and freed the surviving delegates , who fled back home to warn their civilisations and others of the Dalek attack , save for Chen who was convinced the Daleks were still his allies , which later got him killed . As the Daleks made their final preparations , the Doctor managed to get hold of the Time Destructor with the core in place and activated it , wiping out everything on Kembel , including the Dalek invasion force . ( TV : " The Daleks ' Master Plan " ) This was a huge disaster for the Dalek Empire , as the Dalek Prime considered both the fleet and the Black Dalek lost on Kembel irreplaceable . Back on Earth , Karlton was awaiting word from Chen and for the Dalek invasion to begin , and he was concerned when this did not come to pass . He was then arrested by Senator Diksen and placed on trial for high treason with the sentence being execution . Chen and Karlton ' s parts in the attempted invasion had been exposed by Cory ' s recording which had been found on the body of Bret Vyon . SSS agents also set off for Kembel to arrest Chen , unaware of his fate or the planet ' s destruction . ( PROSE : " The Mutation of Time " ) The wars . With the Dalek plans exposed , the Great War began as several powers retaliated by declared war on the Dalek Empire over the course of the following millennium , which was exactly what the Daleks had sought to prevent by cutting out the heart of human space . ( PROSE : " The Evil of the Daleks " ) One of the earliest shots fired in the wars was a minor victory by Space Security Agent Dryn Faber a very short time after the Kembel incident , when he successfully destroyed a Dalek drilling rig on the water planet of Antalin , costing the Daleks valuable minerals and chemicals they were in the process of mining . Faber was driven by the desire to avenge Cory ' s death , as they had been friends before the events on Kembel . ( PROSE : " War of the Daleks " ) As the Great War continued , the Daleks were overwhelmed . Many of the events that occurred over the centuries , particularly towards the end , were massive Dalek defeats as they were driven back on all fronts : During this time , the Dalek Prime took on the title of Dalek Emperor . ( PROSE : " The Evil of the Daleks " ) End of the wars . Over 1000 years after their defeat on Kembel , Dalek computers predicted that the wars would eradicate the Dalek race in as little as 80 years if the defeats continued . The Dalek Emperor ordered the Daleks to capture the Doctor so that they could force him to conduct research into the Human Factor . This would this unlock the secrets of the Dalek Factor which was to be spread throughout all areas of human history , giving all humans the mentality of a Dalek and preventing the Great War from ever happening . The Supreme Council was responsible for the task . Led by a Red Dalek , an emissary for the Council , the Daleks invaded Theodore Maxtible ' s house on Earth in 1866 and set up operations . They kidnapped Victoria Waterfield and forced her father Edward Waterfield to steal the TARDIS from Earth in 1966 to lure the Second Doctor and his companion Jamie McCrimmon to Maxtible ' s house . The Daleks had the Doctor send Jamie to rescue Victoria so that his behavioural patters could be recorded , from which the Human Factor could be distilled . It was tested on three Daleks , which the Doctor named Alpha , Beta and Omega , and proved successful as they had the mentality of human children . With the experiment complete , the Daleks returned to Skaro after destroying the house , with the Doctor , Jamie , the humanised Dalek s and others following them . There , the Doctor confronted the Emperor and learned of the Daleks ' true plans involving the Dalek Factor . To thwarth the Daleks , the Doctor escaped captivity and infected many more of the Daleks with the Human Factor , and , like Alpha , Beta and Omega , they began to question the orders of their superiors which escalated into a full - scale rebellion . The Emperor Dalek ' s guards , the Black Daleks and the other remaining loyalist forces retaliated and the ensuing battle destroyed the Dalek City , seemingly taking the Dalek race with it and ending the wars . ( TV : " The Evil of the Daleks " , PROSE : " The Evil of the Daleks " ) Aftermath . However , the Dalek Civil War did not end the Daleks as the Doctor predicted it would . In the end , the Emperor ' s forces proved too strong and the rebellion was crushed , ( COMIC : " Bringer of Darkness " ) although Alpha and several other humanised Daleks escaped and fled to the planet Kyrol where they began breeding . They ultimately destroyed themselves to prevent the telepathic parasite Kata - Phobus from feeding on them . ( COMIC : " Children of the Revolution " ) Back on Skaro , the Emperor ' s forces began rebuilding , resulting in the emergence of a new command structure , involving grey Dalek drones which largely replaced replaced the silver Daleks , although not completely , ( TV : " Death to the Daleks " ) and Gold Dalek s which outranked the Black Dalek s . ( TV : " Day of the Daleks " , " Frontier in Space " , PROSE : " Day of the Daleks " , " War of the Daleks " ) The Daleks built an automaton to assassinate Victoria Waterfield . Taking the form of her late father , it waited in the London graveyard where her mother was buried , expecting her to return there . However , by the time she did , a century of neglect , inaction and weather had crippled it , allowing the Doctor to easily destroy it . ( PROSE : " Father Figure " ) Despite further encounters with them , the Doctor tried to deny the survival of the Daleks for a time ( COMIC : " Bringer of Darkness " , PROSE : " The Dark Path " , AUDIO : " Fear of the Daleks " ) but when he first encountered them in his third incarnation , by which point the new hierarchy was in place , he reflected on how he was wrong to believe that they had been utterly defeated . ( TV : " Day of the Daleks " ) The crew of the " Hank Morgan IV " knew of the war with the Daleks but considered it ancient history by their native time period , during the war against the Wall of Noise . ( AUDIO : " The Anachronauts " ) By the far future , the Great War , as with other wars involving the Daleks , was considered a part of the First Segment of Time . ( TV : " The Ark " ) After the Last Great Time War , from the Daleks ' perspective , the New Dalek Paradigm began a war with humanity and the SSS during the 40th century , meaning they were already at war when the Great War began in 4000 .
