The '''''Foundation'' series''' is a [[science fiction]] book series written by American author [[Isaac Asimov]]. First published as a series of [[short stories]] and novellas in 1942–1950, and subsequently in three books in 1951–1953, for nearly thirty years the series was widely known as '''''The Foundation Trilogy''''': ''[[Foundation (Asimov novel)|Foundation]]'' (1951), ''[[Foundation and Empire]]'' (1952), and ''[[Second Foundation]]'' (1953). It won the one-time [[Hugo Award]] for "Best All-Time Series" in 1966.<ref>{{cite web| url=http://www.thehugoawards.org/hugo-history/1966-hugo-awards/| title=1966 Hugo Awards| publisher=[[Hugo Award]]| website=thehugoawards.org| date=26 July 2007| access-date=July 28, 2017}}</ref><ref>{{cite web| url=http://www.nesfa.org/data/LL/Hugos/hugos1966.html| title=The Long List of Hugo Awards, 1966| access-date=July 28, 2017| publisher=[[New England Science Fiction Association]]| archive-date=April 3, 2016| archive-url=https://web.archive.org/web/20160403182439/http://www.nesfa.org/data/LL/Hugos/hugos1966.html| url-status=dead}}</ref> Asimov later added new volumes, with two sequels, ''[[Foundation's Edge]]'' (1982) and ''[[Foundation and Earth]]'' (1986), and two prequels, ''[[Prelude to Foundation]]'' (1988) and ''[[Forward the Foundation]]'' (1993).

The premise of the stories is that in the waning days of a future [[Galactic Empire (Isaac Asimov)|Galactic Empire]], the mathematician [[Hari Seldon]] devises the theory of [[psychohistory (fictional)|psychohistory]], a new and effective [[mathematics]] of [[sociology]]. Using statistical laws of [[mass action (sociology)|mass action]], it can predict the future of large populations. Seldon foresees the imminent fall of the Empire, which encompasses the entire [[Milky Way]], and a [[Dark Ages (historiography)|dark age]] lasting 30,000 years before a second empire arises. Although the momentum of the Empire's fall is too great to stop, Seldon devises a plan by which "the onrushing mass of events must be deflected just a little" to eventually limit this [[interregnum]] to just one thousand years. The books describe some of the dramatic events of those years as they are shaped by the underlying political and social mechanics of Seldon's Plan.

==Publication history==

===Original stories===
The original trilogy of novels collected a series of eight short stories and novellas published in ''[[Astounding Magazine|Astounding Science-Fiction]]'' magazine between May 1942 and January 1950. According to Asimov, the premise was based on ideas in [[Edward Gibbon]]'s ''[[History of the Decline and Fall of the Roman Empire]]'', and was invented spontaneously on his way to meet with editor [[John W. Campbell]], with whom he developed the concepts of the collapse of the [[Galactic Empire (Asimov)|Galactic Empire]], the civilization-preserving Foundations, and psychohistory.<ref>Asimov, Isaac. ''La edad de oro II''. Plaza & Janes. 1987. pp. 252–253 (Spanish language translation of [[The Early Asimov]]) See afterword for the "Legal Rites" story.</ref> Asimov wrote these early stories in his [[West Philadelphia]] apartment when he worked at the [[Philadelphia Naval Yard]].<ref>{{cite news |last1=Soniak |first1=Matt |title=Get sci-fi legend Isaac Asimov a plaque in West Philly |url=https://www.inquirer.com/philly/blogs/trending/Get-sci-fi-legend-Isaac-Asimov-a-plaque-in-West-Philly.html |access-date=6 April 2022 |work=The Philadelphia Inquirer |date=24 April 2013}}</ref>

===''Foundation'' trilogy===
The first four stories were collected, along with a new introductory story, and published by [[Gnome Press]] in 1951 as ''[[Foundation (Asimov novel)|Foundation]]''. The later stories were published in pairs by Gnome as ''[[Foundation and Empire]]'' (1952) and ''[[Second Foundation]]'' (1953), resulting in the "Foundation Trilogy", as the series is still known.<ref>{{cite book |author=Isaac Asimov|title=Foundation's Edge |publisher=Spectra |location=Halmstad |year=1982 |isbn=978-0-553-29338-8 }}</ref>

===Later sequels and prequels===
In 1981, Asimov was persuaded by his publishers to write a fourth book, which became ''[[Foundation's Edge]]'' (1982).

Four years later, Asimov followed up with another sequel, ''[[Foundation and Earth]]'' (1986),<ref>{{cite book |author=Isaac Asimov|title=Foundation and Earth |publisher=Spectra |location=Halmstad |year=2004 |isbn=978-0-553-58757-9 |url=https://archive.org/details/foundationearth00asimrich }}</ref> which was followed by the prequels ''[[Prelude to Foundation]]'' (1988) and ''[[Forward the Foundation]]'' (1993), published after his 1992 death. During the two-year lapse between writing the sequels and prequels, Asimov had tied in his ''Foundation'' series with his various other series, creating a single unified universe. The basic link is mentioned in ''Foundation's Edge'': an obscure myth about a first wave of space settlements with robots and then a second without. The idea is the one developed in ''[[Robots of Dawn]]'', which, in addition to showing the way that the second wave of settlements was to be allowed, illustrates the benefits and shortcomings of the first wave of settlements and their so-called ''[[carbon|C]]/[[iron|Fe]]'' (carbon/iron, signifying humans and robots together) culture. In this same book, the word ''psychohistory'' is used to describe the nascent idea of Seldon's work. Some of the drawbacks to this style of colonization, also called ''Spacer'' culture, are also exemplified by the events described all the way back in 1957's ''[[The Naked Sun]]''.

The link between the Robot and Foundation universes was tightened by letting the robot [[R. Daneel Olivaw]] – originally introduced in ''[[The Caves of Steel]]'' – live on for tens of thousands of years and play a major role behind the scenes in both the Galactic Empire in its heyday and in the rise of the two Foundations to take its place.

== Asimov ''Foundation'' series novels ==

===''Foundation'' (1951)===
{{main|Foundation (Asimov novel)}}
Called forth to stand trial on Trantor for allegations of [[treason]] (for foreshadowing the decline of the Galactic Empire), Seldon explains that his science of psychohistory foresees many alternatives, all of which result in the Galactic Empire eventually falling. If humanity follows its current path, the Empire will fall and 30,000 years of turmoil will overcome humanity before a second empire arises. However, an alternative path allows for the intervening years to be only 1,000 if Seldon is allowed to collect the most intelligent minds and create a compendium of all human knowledge, entitled the ''[[Encyclopedia Galactica]]''. The board is still wary, but allows Seldon to assemble whomever he needs, provided he and the "Encyclopedists" are exiled to a remote planet, Terminus. Seldon agrees to these terms – and secretly establishes a second foundation of which almost nothing is known, which he says is at the "opposite end" of the galaxy.

After 50 years on Terminus, and with Seldon dead, the inhabitants find themselves in a crisis. With four powerful planets surrounding theirs, the Encyclopedists have no defenses but their own intelligence. A vault left by Seldon is due to automatically open and it reveals a recorded [[hologram]] of Seldon, who informs the Encyclopedists that their reason for being on Terminus is false; Seldon did not care whether or not an encyclopedia was created, only that the population was placed on Terminus and the events needed by his calculations were set in motion. In reality, the recording discloses, Terminus was set up to reduce the Dark Ages based on his calculations. It will develop by facing intermittent and extreme "crises" – known as "Seldon Crises" – which the laws governing psychohistory show will inevitably be overcome, simply because human nature will cause events to fall in particular ways which lead to the intended goal. The recording reveals that the present events are the first such crisis, reminds them that a second foundation was also formed at the "opposite end" of the galaxy, and then falls silent.

The Mayor of Terminus City, [[Salvor Hardin]], proposes to play the planets against each other. His plan is a success; the Foundation remains untouched, and he becomes its ruler. The minds of the Foundation continue to develop newer and greater technologies which are more compact and powerful than the Empire's equivalents. Using its scientific advantages, Terminus develops trade routes with nearby planets, eventually taking them over when its technology becomes a coveted commodity. The interplanetary traders become diplomats to other planets. One such trader, [[Hober Mallow]], becomes powerful enough to challenge and win the office of Mayor and, by cutting off supplies to a nearby region, also succeeds in adding more planets to the Foundation's control.

===''Foundation and Empire'' (1952)===
{{main|Foundation and Empire}}
An ambitious general of the emperor of the galaxy perceives the Foundation to be a growing threat and orders an attack on it, using the Empire's mighty fleet of war vessels. The Emperor, initially supportive, becomes suspicious of his general's long-term motive for the attack and recalls the fleet despite being close to victory. In spite of its undoubted inferiority in purely military terms, the Foundation emerges as the victor. Seldon's hologram reappears in the vault on Terminus, and explains to the Foundation that this opening of the vault follows a conflict whose result was inevitable whatever might have been done – a weak Imperial navy could not have attacked them, while a strong navy would have shown itself by its successes to be a threat to the Emperor and been recalled.

A century later, an unknown outsider called [[The Mule (Foundation)|the Mule]] has begun taking over planets at a rapid pace. The Foundation comes to realize, too late, that the Mule is unforeseen by Seldon's plan. [[Toran and Bayta Darell]], accompanied by [[Ebling Mis]] – the Foundation's greatest psychologist – and a court jester named Magnifico, who is familiar with the Mule, set out to Trantor to find the Second Foundation, hoping to bring an end to the Mule's reign. Mis studies furiously in the Great Library of Trantor to figure out the Second Foundation's location to seek its help. He is successful and also deduces that the Mule's success stems from his being a mutant who is able to change the emotions of others, a power he used to first instill fear in the inhabitants of his conquered planets, then to make his enemies devoutly loyal to him. Mis is murdered by Bayta Darell before he can reveal the location because she realized that Magnifico is the Mule and has been using his gifts to help Mis do his research, so that the Mule can subjugate the Second Foundation. The Mule ruefully acknowledges that his feelings for Bayta prevented him from tampering with her mind to block just such interference. He leaves Trantor to rule over his conquered planets while continuing his search.

===''Second Foundation'' (1953)===
{{main|Second Foundation}}
As the Mule comes closer to finding it, the mysterious Second Foundation emerges briefly out of hiding to face the threat. While the first Foundation has developed the physical sciences, the Second Foundation has been developing Seldon's mathematics and the Seldon Plan, along with their use of mental abilities. The Second Foundation launches an operation to deceive and eventually mind control the Mule, whom they return to rule over his kingdom peacefully for the rest of his life, without further thought of conquering the Second Foundation.

As a result, the first Foundation learns something of the Second Foundation beyond the fact that it exists, and comes to have some understanding of its role. This means that their behavior will now be influenced by that knowledge, invalidating the mathematics of the Seldon Plan and placing the Plan itself at great risk. The First Foundation starts to resentfully consider the other a rival, and a small group secretly begins to develop equipment to detect and block the Second Foundation's mental influence. After many attempts to infer the Second Foundation's whereabouts from the few clues, the Foundation is led to believe the Second Foundation is located on Terminus (the "opposite end of the galaxy" for a galaxy with a circular shape). The Foundation uncovers and eliminates a group of 50 members of the Second Foundation, believing they have destroyed it.

The 50 were volunteers who sacrificed themselves so that humanity's collective behavior would once again be predictable and follow the mathematics of the Seldon Plan. The Second Foundation is revealed to be on Trantor, the former Imperial homeworld. The clue "at Star's End" was not a physical clue but based on an old saying, "All roads lead to Trantor, and that is where all stars end".

===''Foundation's Edge'' (1982)===
{{main|Foundation's Edge}}
Believing that the Second Foundation exists (despite the common belief that it has been extinguished), young politician [[Golan Trevize]] is sent into [[exile]] by the Mayor of the Foundation, [[List of minor Foundation series characters#Harla Branno|Harla Branno]], to uncover the Second Foundation; [[Golan Trevize|Trevize]] is accompanied by a scholar named [[Janov Pelorat]]. The reason for their belief is that, despite the unforeseeable impact of the Mule, the Seldon Plan still appears to be proceeding in accordance with the statements of Seldon's hologram, suggesting that the Second Foundation still exists and is secretly intervening to follow the plan. After a few conversations with Pelorat, Trevize comes to believe that a mythical planet called [[Foundation universe|Earth]] may hold the secret to the location. No such planet exists in any database, yet myths and legends refer to it. Trevize believes that the planet is being kept hidden. Unknown to Trevize and Pelorat, Branno is tracking their ship so that if they find the Second Foundation, the first Foundation can take action.

[[Stor Gendibal]], a prominent member of the Second Foundation, discovers a simple local on Trantor who has had a very subtle alteration made to her mind, far more delicate than anything the Second Foundation can do. He concludes that a greater force of Mentalics, those with the ability to read and shape the minds of others, must be active in the Galaxy. Following the events on Terminus, Gendibal tries to follow Trevize, reasoning that by doing so, he may find out who has altered the mind of the Trantor native.

Using the few scraps of reliable information within the myths, Trevize and Pelorat discover a planet called Gaia on which every organism and inanimate object on the planet shares a common mind. Branno and Gendibal, who have followed Trevize, also reach Gaia. Gaia reveals that it has engineered this situation because it wishes to do what is best for humanity but cannot be sure what is best. Trevize's purpose, faced with the leaders of the First and Second Foundations and Gaia, is to be trusted to make the best decision among the three main alternatives for the future of the human race, the First Foundation's path, based on mastery of the physical world and its traditional political organization (i.e., Empire); the Second Foundation's path, based on mentalics and probable rule by an elite using mind control; or Gaia's path of absorption of the entire Galaxy into one shared, harmonious living entity in which all beings and the galaxy would be a part.

After Trevize makes his decision for Gaia's path, the intellect of Gaia adjusts Branno's and Gendibal's minds so that each believes he or she has succeeded in a significant task. (Branno believes she has negotiated a treaty tying Sayshell to the Foundation and Gendibal – now leader of the Second Foundation – believes that the Second Foundation is victorious and should continue as normal.) Trevize remains but is uncertain as to why he is "sure" that Gaia is the correct outcome for the future.

===''Foundation and Earth'' (1986)===
{{main|Foundation and Earth}}
Still uncertain about his decision, Trevize continues the search for Earth along with Pelorat and a local of Gaia, advanced in Mentalics, known as Blissenobiarella (usually referred to simply as Bliss). Eventually, Trevize finds three sets of coordinates which are very old. Adjusting them for time, he realizes that his ship's computer does not list any planet in the vicinity of the coordinates. When he visits the locations, he rediscovers the forgotten Spacer worlds of Aurora, Solaria, and finally Melpomenia. After searching and facing dilemmas on each planet, Trevize still has not discovered any answers.

Aurora and Melpomenia are long deserted but Solaria contains a small population extremely advanced in the field of Mentalics. When the lives of the group are threatened, Bliss uses her abilities (and the shared intellect of Gaia) to destroy the Solarian who is about to kill them. This leaves behind a small child who will be put to death if left alone, so Bliss makes the decision to keep the child as they quickly escape the planet. Eventually, Trevize discovers Earth but it contains no satisfactory answers for him (it is also long-since deserted). It dawns on Trevize that the answer may not be on Earth but on Earth's satellite – the Moon. Upon approaching the planet, they are drawn inside the Moon's core, where they meet a robot named [[R. Daneel Olivaw]].

Olivaw explains that he has been instrumental in guiding human history for thousands of years, having provided the impetus for Seldon to create psychohistory and also the creation of Gaia, but is now close to the end of his ability to maintain himself and will shortly cease to function. Despite replacing his [[positronic]] brain (which contains 20,000 years of memories), he is going to die shortly. He explains that no further robotic brain can be devised to replace his or which will let him continue assisting for the benefit of humanity. Some time can be won to ensure the long-term benefit of humanity by merging Olivaw's mind with the organic intellect of a human – in this case, the intellect of the child that the group rescued on Solaria.

Once again, Trevize is put in the position of deciding if having Olivaw meld with the child's superior intellect would be in the best interests of the galaxy. The decision is left ambiguous (though likely a "yes") as it is implied that the melding of the minds may be to the child's benefit but that she may have sinister intentions.

===''Prelude to Foundation'' (1988)===
{{main|Prelude to Foundation}}
''Prelude to Foundation'' opens on the planet [[Trantor]], the empire's capital planet, the day after [[Hari Seldon]] has given a speech at a mathematics conference. Several parties become aware of the content of his speech (that using mathematical formulas, it may be possible to predict the future course of human history). Seldon is hounded by the Emperor and various employed thugs who are working surreptitiously, which forces him into exile. Over the course of the book, Seldon and [[Dors Venabili]], a female companion and professor of history, are taken from location to location by [[Chetter Hummin]] who, under the guise of a reporter, introduces them to various Trantorian walks of life in his attempts to keep Seldon hidden from the Emperor.
Throughout their adventures all over Trantor, Seldon continually denies that psychohistory is a realistic science. Even if feasible, it may take several decades to develop. Hummin, however, is convinced that Seldon knows something, so he continuously presses him to work out a starting point to develop psychohistory.
Eventually, after much traveling and introductions to various, diverse cultures on Trantor, Seldon realizes that using the entire known galaxy as a starting point is too overwhelming; he then decides to use Trantor as a model to work out the science, with a goal of later using the applied knowledge on the rest of the galaxy.

===''Forward the Foundation'' (1993)===
{{main|Forward the Foundation}}
Eight years after the events of ''Prelude'', Seldon has worked out the science of psychohistory and has applied it on a galactic scale. His notability and fame increase, and he is eventually promoted to First Minister to the Emperor. As the book progresses, Seldon loses those closest to him, including his wife, Dors Venabili, as his own health deteriorates into old age. Having worked his entire adult life to understand psychohistory, Seldon instructs his granddaughter, Wanda, to set up the Second Foundation.

==Development and themes==
The early stories were inspired by [[Edward Gibbon]]'s ''[[The History of the Decline and Fall of the Roman Empire]]''. The plot of the series focuses on the growth and reach of the Foundation, against a backdrop of the "decline and fall of the Galactic Empire." The themes of Asimov's stories were also influenced by the political tendency in [[science fiction fandom]], associated with the [[Futurians]], known as [[John Michel (science fiction)|Michelism]].

The focus of the books is the trends through which a civilization might progress, specifically seeking to analyze their progress, using history as a precedent. Although many science fiction novels such as ''[[Nineteen Eighty-Four]]'' or ''[[Fahrenheit 451]]'' do this, their focus is on how current trends in society might come to fruition and they act as a moral allegory of the modern world. The ''Foundation'' series, on the other hand, looks at the trends in a wider scope, dealing with societal evolution and adaptation rather than the human and cultural qualities at one point in time. In this Asimov followed the model of [[Thucydides]]' work ''The [[History of the Peloponnesian War]]'', as he [[The Foundation of S.F. Success|once acknowledged]].

Asimov tried to end the series with ''[[Second Foundation]]''. However, because of the predicted thousand years until the rise of the next Empire (of which only a few hundred had elapsed), the series lacked a sense of closure. For decades, fans pressured him to write a sequel. In 1982, after a 30-year hiatus, Asimov gave in and wrote what was at the time a fourth volume: ''[[Foundation's Edge]]''. This was followed shortly thereafter by ''[[Foundation and Earth]]''. This novel, which takes place some 500 years after Seldon, ties up all the loose ends and ties all his Robot, Empire, and Foundation novels into a single story. He also opens a brand new line of thought in the last dozen pages regarding [[Gaia (Foundation universe)|Galaxia]], a galaxy inhabited by a single [[Geist|collective mind]]. This concept was never explored further. According to his widow [[Janet Asimov]] (in her biography of Isaac, ''[[It's Been a Good Life]]''), he had no idea how to continue after ''Foundation and Earth'', so he started writing the prequels.

==Asimov's imprecise future history==
[[File:Heinlein-decamp-and-asimov.jpg|thumb|Asimov (right) was inspired by the ''[[Future History (Heinlein)|Future History]]'' stories of Heinlein (left), but self-consciously wrote that his was "not the beautiful job that Heinlein did, but was actually made up 'ad hoc'".<ref name=":1" />]]
In the spring of 1955, Asimov published a [[future history]] of humanity in the pages of ''[[Thrilling Wonder Stories]]'' magazine based upon his thought processes concerning the Foundation universe at that point in his life. According to the publication, "the scheme was not originally worked out as a consistent pattern and only includes about one-quarter of his total writings". Because of this, the dating in the ''Foundation'' series is approximate and inconsistent.<ref name=":1" />

Asimov estimates that his ''Foundation'' series takes place nearly 50,000 years into the future, with Hari Seldon born in 47,000 CE.<ref name=":1">{{Cite book|url=http://archive.org/details/Thrilling_Wonder_Stories_v44n03_1955-Winter_bogof39-slpn|title=Thrilling Wonder Stories v44 n03 1955 Winter (bogof39 slpn)|date=1955 |pages=62–63}}</ref> Around this time, the future emperor Cleon I is born in the imperial capital Trantor, 78 years before the Foundation Era (FE) and the events of the original Foundation trilogy.

Asimov himself commented that his fiction's internal history was "actually made up ad hoc.

If some reader checks my stories carefully and finds that my dating is internally inconsistent, I can only say I'm not surprised."<ref name=":1" />

== Prequel trilogy after Asimov's death==
A second Foundation trilogy of prequels was written after Asimov's death by three authors, authorized by the Asimov estate.  These were ''[[Foundation's Fear]]'' (1997) by [[Gregory Benford]], ''[[Foundation and Chaos]]'' (1998) by [[Greg Bear]], and ''[[Foundation's Triumph]]'' (1999) by [[David Brin]].<ref>{{cite web|url=https://sf-encyclopedia.com/entry/foundation_series|title=SFE:Foundation|date=17 January 2022|website=The Encyclopedia of Science Fiction}}</ref>

==Cultural impact==
===Impact in nonfiction===
In ''Learned Optimism'',<ref>[[Martin Seligman|Seligman, Martin]]. ''Learned Optimism'' ((c) 1998 by Alfred A. Knopf, Inc.), 185ff.</ref> psychologist [[Martin Seligman]] identifies the ''Foundation'' series as one of the most important influences in his professional life, because of the possibility of predictive sociology based on psychological principles. He also lays claim to the first successful prediction of a major historical (sociological) event, in the [[1988 United States presidential election|1988 US elections]], and he specifically attributes this to a psychological principle.<ref>Seligman discusses the successful prediction of the Presidential and 33 Senatorial elections based on an evaluation of the candidates' optimism as expressed in their speeches, and the principle that American voters systematically favor optimistic candidates.</ref>

In his 1996 book ''To Renew America'', [[Speaker of the United States House of Representatives|U. S. House Speaker]] [[Newt Gingrich]] wrote that he was influenced by reading the ''Foundation'' trilogy in high school.<ref>[http://historynewsnetwork.org/article/143446 "Newt Gingrich the Galactic Historian"]. [[Ray Smock]], [[History News Network]], 08 December 2011.</ref>

[[Paul Krugman]], winner of the 2008 [[Nobel Memorial Prize in Economic Sciences]], credits the ''Foundation'' series with turning his mind to economics, as the closest existing science to psychohistory.<ref>{{cite web|url=https://www.theguardian.com/books/2012/dec/04/paul-krugman-asimov-economics|title=Paul Krugman: Asimov's Foundation novels grounded my economics|first=Paul|last=Krugman|date=4 December 2012|website=the Guardian}}</ref><ref>{{Cite web|url=https://www.pbs.org/newshour/bb/business/july-dec08/nobelkrugman_10-13.html|title=U.S. Economist Krugman Wins Nobel Prize in Economics|website=[[PBS]]|access-date=2017-08-28|archive-date=2014-01-22|archive-url=https://web.archive.org/web/20140122042610/http://www.pbs.org/newshour/bb/business/july-dec08/nobelkrugman_10-13.html|url-status=dead}}</ref>

Stating that it "offers a useful summary of some of the dynamics of far-flung imperial Rome", [[Carl Sagan]] in 1978 listed the ''Foundation'' series as an example of how science fiction "can convey bits and pieces, hints and phrases, of knowledge unknown or inaccessible to the reader".<ref name="sagan19780528">{{Cite news |url=https://www.nytimes.com/1978/05/28/archives/growing-up-with.html |title=Growing up with Science Fiction |last=Sagan |first=Carl |date=1978-05-28 |work=The New York Times |access-date=2018-12-12 |page=SM7 |language=en-US |issn=0362-4331}}</ref> In the nonfiction PBS series ''[[Cosmos: A Personal Voyage]]'', Sagan referred to an ''Encyclopedia Galactica'' in the episodes "Encyclopaedia Galactica" and "Who Speaks for Earth".

===Awards===
In 1966, the ''Foundation'' trilogy beat several other science fiction and fantasy series to receive a special [[Hugo Award]] for "Best All-Time Series". The runners-up for the award were the ''[[Barsoom series]]'' by [[Edgar Rice Burroughs]], the ''[[Future History (Heinlein)|Future History series]]'' by [[Robert A. Heinlein]], the ''[[Lensman series]]'' by [[Edward E. Smith]] and ''[[The Lord of the Rings]]'' by [[J. R. R. Tolkien]].<ref name="Hugo">{{cite web|url=http://www.thehugoawards.org/hugo-history/1966-hugo-awards/|title=1966 Hugo Awards|date=26 July 2007}}</ref> The Foundation series was the only series so honored until the establishment of the "Best Series" category in 2017. Asimov himself wrote that he assumed the one-time award had been created to honor ''The Lord of the Rings'', and he was amazed when his work won.<ref>{{cite book|title= In Joy Still Felt: The Autobiography of Isaac Asimov, 1954–1978|last= Asimov|first= Isaac|date= 1980|publisher= Doubleday|location= Garden City, New York|isbn= 978-0-385-15544-1|at= [https://archive.org/details/injoystillfelt00isaa/page/ chapter 24]|url= https://archive.org/details/injoystillfelt00isaa/page/}}</ref>

The series has won three other Hugo Awards. ''Foundation's Edge'' won Best Novel in 1983, and was a bestseller for almost a year. Retrospective Hugo Awards were given in 1996 and 2018 for, respectively, "The Mule" (the major part of ''Foundation and Empire'') for Best Novel (1946) and "Foundation" (the first story written for the series, and second chapter of the first novel) for Best Short Story (1943).

===Impact in fiction and entertainment===
[[Douglas Adams]]' ''[[The Hitchhiker's Guide to the Galaxy]]'' mentions the encyclopedia by name, remarking that it is rather "dry", and consequently sells fewer copies than his own creation "The Guide".<ref>{{cite book |last1=Adams |first1=Douglas |author1-link=Isaac Asimov |title=The Hitchhiker's Guide to the Galaxy |date=2005 |publisher=Del Rey/Ballantine Books |location=New York |isbn=978-0-307-41713-8 |chapter=Chapter 2}}</ref>

[[Frank Herbert]] also wrote ''[[Dune (novel)|Dune]]'' as a counterpoint to ''Foundation''. Tim O'Reilly in his monograph on Herbert wrote that "''Dune'' is clearly a commentary on the ''Foundation'' trilogy. Herbert has taken a look at the same imaginative situation that provoked Asimov's classic—the decay of a galactic empire—and restated it in a way that draws on different assumptions and suggests radically different conclusions. The twist he has introduced into ''Dune'' is that the Mule, not the Foundation, is his hero."<ref>{{Cite web|url=https://www.oreilly.com/tim/herbert/ch05.html|title=Frank Herbert, Chapter 5, Rogue Gods|website=[[oreilly.com]]|access-date=May 15, 2020}}</ref>

In 1995, [[Donald Kingsbury]] wrote "Historical Crisis", which he later expanded into a novel, ''[[Psychohistorical Crisis]]''. It takes place about 2,000 years after ''Foundation'', after the founding of the Second Galactic Empire. It is set in the same fictional universe as the Foundation series, in considerable detail, but with virtually all ''Foundation''-specific names either changed (e.g., Kalgan becomes Lakgan), or avoided (psychohistory is created by an unnamed, but often-referenced Founder). The novel explores the ideas of psychohistory in a number of new directions, inspired by more recent developments in mathematics and [[computer science]], as well as by new ideas in science fiction itself.{{cn|date=March 2024}}

In 1998, the novel ''[[Spectre (Star Trek)|Spectre]]'' (part of the [[Shatnerverse]] series) by [[William Shatner]] and [[Judith and Garfield Reeves-Stevens]] states that the [[Mirror Universe]] divergent path has been studied by the ''Seldon Psychohistory Institute''.{{cn|date=March 2024}}

According to lead singer [[Ian Gillan]], the hard rock band [[Deep Purple]]'s song ''The Mule'' is based on the Foundation character: "Yes, The Mule was inspired by Asimov.

=== Adaptations ===
==== Radio ====
{{main|The Foundation Trilogy (BBC Radio)}}
An eight-part [[The Foundation Trilogy (BBC Radio)|radio adaptation]] of the original trilogy, with sound design by the [[BBC Radiophonic Workshop]], was broadcast on [[BBC Radio 4]]<ref>{{Cite web|url=https://genome.ch.bbc.co.uk/d72b48f863784e7f85feae8bc9c2cbce|title=Broadcast - BBC Programme Index|website=genome.ch.bbc.co.uk|date=17 September 1977 }}</ref> in 1973—one of the first BBC radio drama serials to be made in [[stereophonic sound|stereo]]. A [[BBC 7]] [[rerun]] commenced in July 2003.

Adapted by [[Patrick Tull]] (episodes 1 to 4) and Mike Stott (episodes 5 to 8), the dramatisation was directed by [[David Cain (composer)|David Cain]] and starred William Eedle as Hari Seldon, with [[Geoffrey Beevers]] as Gaal Dornick, [[Lee Montague]] as Salvor Hardin, [[Julian Glover]] as Hober Mallow, [[Dinsdale Landen]] as Bel Riose, [[Maurice Denham]] as Ebling Mis and [[Prunella Scales]] as Lady Callia.

==== Film ====
By 1998, [[New Line Cinema]] had spent $1.5&nbsp;million developing a film version of the ''Foundation Trilogy''. The failure to develop a new franchise was partly a reason the studio signed on to produce [[The Lord of the Rings (film series)|''The Lord of the Rings'' film trilogy]].<ref>{{cite book | last = Sibley | first = Brian | author-link = Brian Sibley | title = Peter Jackson: A Film-maker's Journey | publisher =Harpercollins | year =2006 | location =London | page =403 | isbn = 978-0-00-717558-1 |chapter=Three-Ring Circus}}</ref>

On July 29, 2008, New Line Cinema co-founders [[Bob Shaye]] and [[Michael Lynne]] were reported to have been signed on to produce an adaptation of the trilogy by their company Unique Pictures for Warner Brothers.<ref>{{cite news | author = Rich Drees| title = 'Foundation' Heading To Big Screen| publisher = Film Buff OnLine | date = 2008-07-29 | url = http://www.filmbuffonline.com/FBOLNewsreel/wordpress/?p=842/ | access-date=2008-07-29}}</ref>
However, [[Columbia Pictures]] (Sony) successfully bid for the screen rights on January 15, 2009, and then contracted [[Roland Emmerich]] to direct and produce. Michael Wimer was named as co-producer.<ref>{{IMDb name|0000386|Roland Emmerich}}</ref>
Two years later, the studio hired [[Dante Harper]] to adapt the books.
