Dalek Empire

The Dalek Empire was an empire created by the Daleks which spanned much of time and space. With a goal to exterminate all life save the Daleks themselves, the Empire waged numerous interstellar wars, bringing it into frequent conflict with the Doctor. It was divided for a time during its civil war, but was eventually reunited. Ultimately, the entire Empire fought the Time Lords in the Last Great Time War, which was marked by unprecedented destruction across time. The Dalek Empire ceased to exist when the war ended, although remnants survived. One of the survivors of the Dalek Empire, Dalek Caan, went on to become the founder of the New Dalek Empire, which itself would later be succeeded by a third empire.

Origins
The Empire was formed during an unknown period in Dalek history, presumably after venturing into space from their home planet of Skaro. Events from this period included their initial invasion of Earth. (TV: The Dalek Invasion of Earth)

The Daleks began to come into conflict with the Doctor, prompting them to focus their efforts on creating their own means of time travel, resulting in them constructing time machines. They attempted to hunt down the Doctor through time and space, but failed when the Doctor trapped them in a conflict with the Mechanoids. (TV: The Chase)

Expanding the Empire

 * As always, time travel makes the sequence of events here conjectural.

Settling down to more general use of their time travelling abilities, the Daleks proceeded on a grand effort to create a permanent base of operations. Using knowledge from the library of Kar-Charrat (AUDIO: The Genocide Machine) and the power of Gallifrey, the Daleks obliterated the entire Seriphia Galaxy, remaking it to their own designs. (AUDIO: The Apocalypse Element) From there, the Daleks staged several major invasions of the Mutter's Spiral, notably in the 42nd and 67th centuries. (AUDIO: Dalek Empire)



Despite having their own galaxy, the Dalek Emperor maintained himself on the home planet of Skaro, and continued efforts from there to take over Earth at various points in history. (TV: The Daleks' Master Plan, The Evil of the Daleks, Day of the Daleks)

After the resurrection of the Daleks' creator Davros during the Movellan war, (TV: Destiny of the Daleks) the Daleks entered a new era, led by Davros as the new Emperor. (COMIC: Emperor of the Daleks!) A schism developed between the Imperial Daleks loyal to Davros and Renegade Daleks loyal to the Dalek Supreme. The subsequent Imperial-Renegade Dalek Civil War stretched across the entire Dalek Empire. As the war escalated, the Seventh Doctor set a trap for factions, resulting in the destruction of (TV: Remembrance of the Daleks) Skaro's second sun. (PROSE: The Stranger)

The Dalek Prime and Davros survived the war and encountered one another once more during a decline in Dalek pervasiveness throughout the galaxy. Davros was again defeated and the Dalek Prime set about rebuilding the Empire. (PROSE: War of the Daleks)

Last Great Time War and destruction


United once more, the Daleks, including Davros (TV: The Stolen Earth) and a new Dalek Emperor, (TV: Bad Wolf) fought the Time Lords in the Last Great Time War, a titanic battle across all of history, resulting in the near-total destruction of both sides. (TV: Dalek) It was eventually revealed that "all thirteen" incarnations of the Doctor (led by the War, Tenth and Eleventh Doctors) came together to save the Time Lords and Gallifrey which was under attack by the entire empire, a "billion billion" Daleks in millions of ships. When the Doctor moved Gallifrey into a pocket universe, the Daleks were caught in their own crossfire and they destroyed themselves (rather than being destroyed along with the Time Lords by the War Doctor with the Moment, as previously believed). (TV: The Day of the Doctor)

Remnants
There were at least four different instances of Dalek survivors of the Time War: a single drone which fell through time, landing on Earth in the 20th century, (TV: Dalek) the Dalek Emperor himself, (TV: The Parting of the Ways) the four-member Cult of Skaro, in possession of a Genesis Ark containing millions of trapped drones (TV: Doomsday) and the inmates of the Dalek Asylum, a prison planet containing thousands of insane and damaged Daleks. (TV: Asylum of the Daleks)

Further Dalek empires
After the destruction of the Dalek Empire, two subsequent empires were established: the New Dalek Empire, followed by the New Dalek Paradigm.

The New Dalek Empire was established by Dalek Caan, who made a perilous journey back through time into the first year of the Time War, and rescued Davros from the "jaws of the Nightmare Child". Davros sacrificed cells from his own body to create millions of new Daleks. Together they built a massive fleet and a space station called the Crucible within the Medusa Cascade. Dalek Caan worked in secret to betray the New Empire and Davros, however, and assisted the Doctor and Donna Noble in disarming the reality bomb and foiling the stolen planets plot. The Meta-Crisis Tenth Doctor then caused a chain reaction which destroyed the New Empire, including apparently Davros and Caan. (TV: The Stolen Earth, Journey's End)



Through a deception called the "Ironside Project", three Daleks, having survived a previous encounter with the Doctor, tricked the Eleventh Doctor into helping them activate the Progenitor. The device then created five new Daleks, referred to as a New Dalek Paradigm. These newcomers destroyed their three forebears and escaped through a time corridor. Amy Pond speculated that the new Daleks would need time to "build themselves up". (TV: Victory of the Daleks) The Paradigm's new empire would eventually grow to be overseen by a Parliament led by a Dalek Prime Minister. (TV: Asylum of the Daleks)

The Daleks at some point after a vast Galactic Recession established the Sunlight Worlds, 400 worlds and the planet Carthedia acting as a government state. Humans were allowed to live there, not knowing of the danger of the Daleks. The Dalek time controller planned to use the Cradle of the Gods to turn the Sunlight Worlds into copies of Skaro. However the Eleventh Doctor and Jenibeth Blakely foiled this plan. (PROSE: ''The Dalek Generation)

Alternate timelines
Following their escape, the new Daleks discovered the lost Time Lord artefact, the Eye of Time, allowing them to alter time as they saw fit. The Daleks returned to Skaro, rebuilt their capital city of Kaalann, appointed a new emperor, and began rebuilding their empire. One of the empire's first acts with their new-found power over time was to invade Earth in 1963. In this new timeline, they succeeded in killing every member of the human race. However, the Doctor and Amy Pond successfully undid these events, leaving Earth unconquered and erasing the new empire from existence. (GAME: City of the Daleks)

Another alternate timeline was created when guerrillas from this timeline travelled back and accidentally caused a war by assassinating delegates, allowing the Daleks to invade Earth. This was averted when the Third Doctor travelled back from this timeline and told the guerrilla responsible the truth. Daleks and Ogrons travelled back to keep this timeline intact, but the guerrilla destroyed them with a bomb. (TV: Day of the Daleks)

In another alternate timeline, the Daleks invaded Earth in the 17th century. This was averted by the Eighth Doctor and Charley Pollard. (AUDIO: The Time of the Daleks)
