The Galactic Federation was the political entity that succeeded the Earth Empire as the dominant galactic power.

Philosophy and mission[]

The Federation was designed to ensure peaceful relations between the many species in the galaxy, with emphasis on cooperation rather than competition in matters of trade and policy. It was formed to help the unstable economy of the Galaxy after the collapse of the Earth Empire. (PROSE: Legacy)


The headquarters of the Federation was located on Alpha Centauri in 3375, though Jupiter's moon Io was eventually chosen as the Federation Chair. (PROSE: The Dark Path)

Each member of the Federation took a chairmanship for a limited term. Any decision had to be by unanimous vote. (PROSE: The Dark Path, TV: The Curse of Peladon)

The Guardian of the Solar System was a Federation title. (PROSE: Uranus) Mavic Chen held the title in 4000. (TV: The Daleks' Master Plan)


The Federation guaranteed full planetary sovereignty to its member worlds, meaning that the Federation council could not interfere with the local laws and customs of individual planets. (TV: The Curse of Peladon, The Monster of Peladon)


Known members included Alpha Centauri (TV: The Curse of Peladon), Arcturus (TV: The Curse of Peladon), Arviem 2 (AUDIO: The Revolution), Draconia (PROSE: The Dark Path), Earth (TV: The Curse of Peladon), Mars (TV: The Curse of Peladon), Peladon (TV: The Monster of Peladon), Terileptus (PROSE: The Dark Path), Vega (TV: The Monster of Peladon), Veltroch (PROSE: The Dark Path), Liasici (PROSE: Placebo Effect), Thoros Beta (PROSE: The Dark Path), Balhoon (COMIC: Reunion of Fear), Zygor (PROSE: The Bodysnatchers), Xlanthius (PROSE: Beige Planet Mars) and Emindar (PROSE: Vanderdeken's Children)


According to one account, the Federation was already in existence by 1979, with the Solar system already within Federation space. By this time, the Slarvians had petitioned to join the Federation many times, to no avail. (PROSE: Childhood Living)

By another account, the Federation wasn't formed until the first third of the 32nd century, after the collapse of the Earth Empire and its old alliances. Earth, New Mars, and Draconia were founding members. (PROSE: Legacy)

In 3375, the Federation tried to integrate the Empire remnants at Darkheart colony into the new system. (PROSE: The Dark Path)

Peladon was admitted to the Federation during King Peladon's reign, despite the efforts of the delegate from Arcturus and High Priest Hepesh to sabotage its assessment. (TV: The Curse of Peladon)

Five years after Peladon joined the Federation, the Federation Council had Alpha Centauri secretly hide the Princess Lixgaar on Peladon to keep her safe after the rest of the Martian royal family was executed by the New Martian Republic. (AUDIO: The Prisoner of Peladon)

Late in King Peladon's reign, Lord Ixmari was sent to carry out a surprise Federation inspection on Peladon. (AUDIO: The Ordeal of Peladon)

During Queen Thalira's reign on Peladon, the Federation was at war with Galaxy 5. They made numerous attempts to broker a peace deal but Galaxy Five refused to cooperate. The Federation became dependant on trisilicate supplies mined on Peladon which two Galaxy 5 agents, Eckersley and Azaxyr, conspired to seize. They were foiled and Galaxy 5 quickly agreed to a peace deal. (TV: The Monster of Peladon, PROSE: Doctor Who and the Monster of Peladon)

Following a galactic alert warning of plague and imminent republican uprising on Peladon, a group of Federation delegates went dispatched to Peladon. After River Song uncovered numerous plots and a Karg Mafia agent within the delegates, delegate Alpha Centauri promised to write a positive report to the Federation. (AUDIO: The Poison of Peladon)

In 4010, when the asteroid Maleficent was due to collide with the planet Uranus, it was sabotaged so that it would collide with the Hub. Branko Chen hoped to seize power with his followers and become the new Guardian of the Solar System in the aftermath of the Federation's communications being knocked out. When his plan failed due to the intervention of the Seventh Doctor, he tried to escape in his Spar but was arrested by his own Technix. (PROSE: Uranus)

During Queen Minaris's reign, relations between Peladon and the Federation became tense so Alpha Centauri served as a liaison despite being semi-retired. After Princess Isabelda's role in causing a mining disaster and insurrection was exposed, the Queen accepted Centauri's efforts to organise Federation aid to the planet and Centauri decided to remain on Peladon as a special ambassador. (AUDIO: The Death of Peladon)

The Federation had an incursion with the Ba-El Cratt in the 51st century after the Human Empire unknowingly entered an agreement with their enemies, the Cancri, to supply them diamonds for their war effort. (PROSE: Diamond Dogs)

The Federation starship Nepotist became part of Daedalus' plot to bring the war in the Enclave into the outside universe. The Federation was predicted to be one of the many forces to follow the Daleks into the war. The Eighth Doctor was present at the beginning of these events, but Iris Wildthyme prevented him from taking part in their outcome. (PROSE: The Blue Angel)

While it was a Federation member, Earth and its colonies were also organised into the Earth Alliance. (AUDIO: The Sirens of Time) The Federation was later replaced as the dominant galactic power by the Second Great and Bountiful Human Empire. (TV: Planet of the Ood)

A Federation was still around by the ninth millennium but had been corrupted by the descendants of Mavic Chen. An uprising of democrats sparked a civil war, which ended in the Federation being replaced with the Union. In the tenth millennium, it bordered the Draconian Republic. In 10674 the Doctor claimed the Union would be replaced by the brutal Junta in a century, although he later said he'd made up some future history. (PROSE: The Crystal Bucephalus)

Circa 2000000, the Galactic Federation was still around, and included Avalone. (PROSE: Head Games)

According to the Fourth Doctor, the Galactic Federation ultimately built an all-powerful justice machine to settle disputes across all its lifeforms. However, the machine found the Federation in contempt of court and blew up the galaxy. (TV: The Stones of Blood, PROSE: Doctor Who and the Stones of Blood)
