Asimov created the Galactic Empire in the early 1940s based upon the Roman Empire, as a proposal to John W. Campbell, after reading Edward Gibbon's The History of the Decline and Fall of the Roman Empire when he was working at the Philadelphia Navy Yard with Robert Heinlein. The concept evolved through short stories and novellas in Astounding Science Fiction magazine during the 1940s, culminating in the publication of the Foundation stories as a trilogy of books in the early 1950s.[1][2]

As of 827 G.E. (Galactic Era, the number of years after its founding), the Galactic Empire comprises millions of inhabited worlds with 500 quadrillion residents.[3] According to the Foundation series chronology established in the late 1990s, it comes into existence approximately 10,000 CE, year one of the Galactic Era. (The establishment of the Empire was originally 34,500 CE, according to Asimov's unofficial unpublished early 1950s chronology.) The Galactic Empire was made possible by the ability of humans to travel through hyperspace. The space navy of the Galactic Empire is called the "Imperial Navy".[4] The empire's capital, named Trantor, is the closest habitable planet to the center of the galaxy, and the novels in the Foundation trilogy describe its fall, over a period of centuries, and a period of anarchy and decay, a parallel to the fall of the Western Roman Empire and the Dark Ages.

Asimov posits that two foundations are instituted to restore the empire to its former glory. Through the use of psychohistory, a future science hypothesized by Asimov, a scientist on Trantor named Hari Seldon in about 12,000 Galactic Era predicts the fall of the empire, and institutes the two foundations.[2][5]

The Periphery

The Periphery is a fictional location in Isaac Asimov's Foundation Series and refers to the outer rims of the Galactic Empire, including planets such as Anacreon and Santanni. Imperial control is weakest in the periphery, as planet governors there frequently possess their own fleets. Santanni revolts during Forward the Foundation. About 50 years after the First Foundation is established on Terminus, the emperor will grant the periphery autonomy. This effectively removes them completely from Imperial control, making the dissolution of the Empire far more apparent than it had been before.

In the years preceding the fall of Trantor, the periphery became any area outside the empire as this area became larger the empire became less and less great.

As the empire decreased in size and power, the stagnation that would ultimately cause the collapse of the empire increased.


A complete list of Galactic emperors and their dynasties does not exist; however, a number of names and their rule are known:

Name Dynasty Notes
Frankenn I Kamble The first Galactic Emperor.
Loris VI
Aburanis Introduced the "Law Codes of Aburanis."
Kandar V Transplanted the last inhabitants of Earth to Alpha Centauri.
Agis VI[6] Wyan Followed by Entun dynasty ca. 11,830 GE.
Manowell Entun Nicknamed "Bloody Emperor."
Stanel VI Entun Father of Cleon I.
Cleon I Entun Ruled from 11,988 GE – 12,038 GE. He was assassinated by his chief gardener.
Interregnum between 12,038 and 12,058 GE. Rule by a military junta.
Agis XIV
Daluben IV Ruled during the time of the Seldon Trial.
Stannell VI Died 104 FE.
Ammenetic the Great Mentioned in Foundation and Empire, where Cleon II reminds that his grandfather was merely a pirate, and he now lives "in the luxurious palace of Ammenetic the Great." There is no information to position Ammenetic on the list of Emperors. and to assign him to a dynasty, except for the obvious fact that he must have lived and ruled before Cleon II.
Cleon II The last strong Emperor.
Dagobert VIII Final ruler of the Galactic Empire. Fled Trantor during the Great Sack by the rebel Gilmer.
Dagobert IX Resided on Neotrantor following the Great Sack of Trantor. At least one more Emperor presumably succeeded him, since the dynasty was stated to have survived for a century after the Sack.

Consensus cosmogony

Asimov's Galactic Empire was the first example after Olaf Stapledon's 1937 science fiction novel Star Maker of one of the eight stages of a "consensus cosmogony", also called the Science Fiction Cosmology, identified by Donald A. Wollheim in the 1950s, which science fiction writers needed only hint at in their stories for experienced SF readers to slot into their perception of future history and envisage the background to the tale without the writers having to expend time and space explicitly laying it out. These stages are:[7]

  1. The initial exploration, colonization, and exploitation of the solar system, including plots modeled on the American War of Independence where the human colonies on Mars, Venus, or other planets declare independence from Earth
  2. The first flights to the stars, with plots similar to those of the preceding stage
  3. The rise of a Galactic Empire, and possible contact, either friendly or hostile, with empires of alien species (in Asimov's galactic empire, only one intelligent nonhuman race is found; it leaves the galaxy in "Blind Alley")
  4. The Galactic Empire at its height, with exploration occurring at its Rim
  5. The Decline and Fall of the Galactic Empire, as explored by Asimov and later other authors
  6. The Galactic Dark Ages, an interregnum with worlds reverting to barbarism, as also partially explored by Asimov
  7. The Galactic Renaissance, where a new democratic Galactic Civilization arises, including the restoration of civilization to and communication with worlds that were isolated during the Fall—this stage was called by Stapledon the Galactic Community of Worlds, was called by Asimov the Foundation Federation, and is most commonly called by most authors the Galactic Federation
  8. The Challenge To God, an effort to solve the last secrets of the universe by transcending matter and morphing into beings of pure energy, the end of time, and the investigation of the beginnings of new universes—Stapledon covers this in the last part of Star Maker and Asimov covers it in his short story The Last Question

Other authors and Asimov's universe

Bondanella (listed in Further reading) analyzes Asimov's Galactic Empire as an example of the influence of the myth and history of the Roman Empire upon modern fiction. Asimov himself wrote two non-fiction books on the subject of the Roman Empire, aimed at the mass market and young readerships, The Roman Republic in 1966 and The Roman Empire in 1967, reflecting the positive view of the Roman Empire that then prevailed, as it was considered the prototype of the rising American Empire. After the cinematic release of the first Star Wars trilogy, another parallel to the Roman Empire that presents the negative view of the empire that became widely prevalent in late 20th and early 21st century popular culture as a result of the negative view of the American Empire resulting from the Vietnam War, Asimov revisited his Galactic Empire and wrote further novels in the Foundation series. Other writers to have been influenced by the Roman Empire include, of course, those who have written novels set in Asimov's universe of the Galactic Empire, such as David Brin's Foundation's Triumph, and Robert Silverberg, who wrote of an alternative universe in which the Roman Empire never fell, and who edited Far Horizons (listed in Further reading) which contains several examples of Asimov's influence upon science fiction. Brian Herbert and Kevin J. Anderson's Dune: House Atriedes (1999) is, similarly, a Greek parallel to ancient Rome.[8]

Other works to have been influenced by Asimov's Empire include Donald Kingsbury's Psychohistorical Crisis, whose galactic empire, and the scholar-empire that succeeds it, are clearly based upon Asimov's Galactic Empire and the Foundations, albeit that Kingsbury was not granted permission to set his work directly in Asimov's universe. Seed calls this work "perhaps the most remarkable homage that any SF writer has received from another SF writer".[9]

Asimov's Galactic Empire, its decline, fall, and rebirth, in particular, is characterized by Perelman as a simple repetition of the history of Western Civilization from the fall of the Roman Empire to the 20th century, borrowing freely from Toynbee, and a validation of postwar American culture of the 1940s and 1950s, with the Second Galactic Empire being "definitely suburban".[10]

Other writers to explore the cycles of civilisations in their works include James Blish, who studied the works of Oswald Spengler and whose novels Cities in Flight, They Shall Have Stars, A Life for the Stars, Earthman Come Home, and The Triumph of Time portray the rise and fall of the galaxy as an inevitable cycle, of which (unlike in other dystopian SF stories of the 1940s and 1950s) the use of machine technology is merely a symptom not the actual cause, and culminate, as in Wollheim's eighth stage, with the end of the universe and the birth of a new one.[2][11]

Colin Manlove characterizes Asimov's description of the Galactic Empire, its people, its culture, its history, and its planets, laid out in the Foundation novels as an aesthetic monotony: "persons are usually seen as typical rather than special, even as clichés … the mutant Mule […] is not given a personality, he is merely a powerful anomaly … Nor do we hear much of landscapes, apart from Trantor and one sea-scape … we do not know how one planet differs from another, as, say, Ursula K. Le Guin differentiates the desert Anarres from the lush twin Urras … Nor are we given details of battles, lingering accounts of love, different customs of civilisations. There are no animals, only man. … Thought-processes and conversations largely fill the trilogy, and nearly all these are confined to finding things out and with gaining power."[12][13]
