|Birth Of Susan Calvin. Incorporation of U.S. Robots and Mechanical Men.
|Susan Calvin begins to work for U.S. Robots. Later becomes chief robopsychologist.
|Early 21st C
|A social and technical renaissance flourishes on Earth. Development of positronic robots, controlled by the Three Laws of Robotics. Hyperatomic Drive allows first successful interstellar journey. Through an accident, Joseph Schwartz is sent on a time journey 10,000 years into the future.
|Death of Susan Calvin. Humanity begins colonizing several planets including Aurora. The first chaos outbreaks affect civilization, breaking down confidence. On Earth, citizens cluster underground, ban robots from cities. Spacers lose empathy. Relations between Earth and Spacer Worlds deteriorate.
|The planet Solaria [the last Space world] settled from the planet Nexon. Decline of the robot-dependent Spacer culture. Later, Han Fastolfe of Aurora creates the humaniform robot,R. Daneel Olivaw.
|SpaceTown is established near New York City. R. Daneel Olivaw is assigned to work with Earthman detective Elijah Bailey.
|Elijah Bailey and Daneel Olivaw pursue an investigation on Solaria. Fastolfe becomes influential in Auroran government and supports new Earth emigration. Opponents led by Keldon Amadiro want Spacers to terraform and populate new planets.
|Baley carries out investigation on Aurora accompanied by Daneel Olivaw and Giskard Relentlov –a telepathic robot. Aurora lets Earth colonize new planets. Giskard suggests Earth folk must build their new worlds completely without robots.
|The second wave of emigration from Earth begins, led by Ben Baley. First Settler planet is named BaleyWorld. Number of Settler planets grows fast. Relations between Settler and Spacer worlds grow tense.
|Death of Elijah Bailey on BaleyWorld.
|Kelden Amadiro and Levular Mandamus begin planting nuclear amplifiers throughout Earth to take revenge for their earlier defeat.
Death of Han Fastolfe. Population of Solaria vanishes. Daneel
Olivaw and Giskard Relentlov formulate the
Zeroth Law of Robotics, to override original
Giskard provides Daneel with telepathic abilities. Amadiro and allies turn on amplifiers to make the Earth radioactive and inhabitable. Giskard permits this for Zeroth Law reasons, in order to encourage human dispersal, then dies because of First Law conflicts.
The Great Diaspora (final emigration) begins. A majority of robots split into two camps. Giskardians led by Daneel follow the new Zeroth Law religion. Calvinians think this an outrage.Robotic civil war ensues, mostly unseen by humans fleeing poisoned Earth.
Meanwhile robot ships operating under Auroran programming cruise the galaxy ahead of the spreading Settlers, terraforming and preparing planets for colonization. Meme entities will later claim that this devastated existingraces. Memes escape to the Galactic Core.
|Spacer-colonized planet Inferno is doomed by ecological and cultural catastrophe. Robots are built to operate under New Laws, giving them greater flexibility and freedom. Settler specialists help terraform the planet. Hostility toward New Law robots grows evident. Comet crashes into the planet. Merging of Spacer and Settler culture prevents social collapse. The interstellar robot civil war eventually reaches Inferno. New Law robots are destroyed or go into hiding.
Planet Rhodia and the Nebular Kingdoms led by the noble Hinriad
family shake off rule by planet Tyrann and rediscover democracy.
Decadent Spacer worlds slowly die out.
Colonization of Galaxy completed. R. Daneel Olivaw formulates the Encoding Laws, setting limits to artificial intelligence. Damping effects such as historical amnesia, brain fever, and Giskardian mentalic persuasion devices are introduced to fight chaos, Human mind, society and technology stagnate. Some human and robot groups fight the amnesia.
Trantorian Republic of five worlds becomes Trantorian
Confederation, then later the Trantorian Empire.
R. Daneel Olivaw uses early "laws of humanics" to guide it. Human origins forgotten.
|Half of the inhabited worlds of the Galaxy are part of Trantorian Empire. Trantor supports rebellion of planet Florina against oppression by planet Sark.
|12500 C.E | 1 G.E
|Trantorian Empire becomes the Galactic Empire. Start of Galactic Calendar.
|Arrival of Joseph Schwartz (thrown forward in time during the early 21st Century). A radioactive sparsely populated Earth tries to revolt against the Empire by using a bio-weapon. Rebellion fails, thanks partly to Schwartz and a mentalic amplifier. Empire initially helps Earth recover, then effort is mysteriously abandoned.
|Forced evacuation of inhospitable Earth. Establishment of colony on planet Alpha.
|An alien race is discovered on a desert world and moved to Cepheus 18. Later they mysteriously escape beyond the Galaxy.
|Daneel Olivaw and R. Yan Kansarv establish a robot production and repair facility on distant Eos. The great Emperor Ruellis helps establish principles of good paternalistic government, augmenting the stability of an unchanging society against chaos.
|During a chaos outbreak, ancient personality simulations Voltaire and Joan of Arc debate about machine intelligence. With support of Calvinian robots, the Empress Shoree-Harn tries to introduce a new calendar and shake up social rigidity without success.
|A new "renaissance" begins on planet Lingane. Falls into chaos eight years later.
|Humanoid robot Dors Venabili is constructed on Eos
|The only extragalactic human colony is abandoned in the Greater Magellanic Cloud. All data is suppressed.
|Birth of Hari Seldon and Cleon I. Daneel Olivaw knows the Empire is destabilizing, partly due to frequent chaos outbreaks. He is forced by the Zeroth Law to actively interfere, first as Chief of Staff, then as First Minister. His secret genetic experiments lead both to Hari's mathematical genius and the appearance of human mentalics.
|Cleon I becomes Emperor.
|Hari Seldon lectures on possibility of psychohistory. Daneel persuades him to develop a practical science to help save the Empire. Dors Venabili becomes Seldon's wife. They adopt a boy, Raych. Seldon and Yugo Amaryl begin to flesh out psychohistory.
|Calvinian robots, led by R. Plussix, move to Trantor and find historical documents dating from era of Shoree-Harn, as well as the sims Voltaire and Joan of Arc. They help seed a new "renaissance" on planet Sark. Seldon helps remove Laskin Joranum from politics. Daneel resigns his post. Cleon I makes Seldon First Minister. Voltaire and Joan get into the Trantorian Mesh where they meet the ancient memes, triggering a rebellion among "tiktok" robots who kill many of Daneel's positronic companions. Seldon strikes a deal to get the memes off Trantor. Sark renaissance falls into chaos.
|Death of Cleon I. A military junta seizes power. Seldon resigns as First Minister.
|Birth of Wanda Seldon, daughter of Raych. A new "renaissance" begins on planet Madder Loss. Its collapse rocks galactic society.
|"Death" of Dors Venabili and Fall of the junta. Puppet Emperor Agis XIV ascends the throne. Real power is in the hands of the Commission for Public Safety. Daneel brings Dors to the Eos base for repair.
|Birth of Bellis Seldon. Hari Seldon discovers Wanda's metal abilities. He tries to find others, without success. Psychohistorical equations predict the unavoidable collapse of the Empire. Seldon team works out plan to save human knowledge and create a Second Empire via the Foundation. Death of Yugo Amaryl.
|Raych, Manella, and Bellis move to Santanni where a New Renaissance has begun. Anacreon Province seeks independence. Chaos breaks out on Santanni, Raych dies, and his family is lost in space. Stettin Palver, another mentalic joins the Seldon Project.
|12067 G.E | 1 F.E
|Puppet Emperor Klayus I sits on the throne. Hari Seldon is put on trail and Commission for Public Safety exiles the Encyclopedia Foundation to Terminus. Beginning of the Foundation Calendar. Vara Liso, a strong mentalic, gets entangled in Farad Sinter's hunt for robot "eternals." Calvinian robots foiled in a plot to ruin Seldon Project and stymie Daneel's control over human history.
|Reign of puppet Emperor Semrin. Members of the Encyclopedia Foundation exiled to Terminus. Daneel plans using human mentalics to design an overmind Gaia. Millions of ancient archives destroyed. A New Renaissance on planet Ktlina is devoured by chaos. A heretic robot tries to send Seldon into the future but is foiled by Daneel. Mors Planch dives into the future.
|Death of Hari Seldon. Chief Commissioner Linge Chen dies. Replacement pays attention mostly to Trantor and vicinity. Psychohistorians provoke succession at Empire's Periphery.
|Anacreon declares independence, separating Terminus from the Empire. Seldon's hologram explains the true purpose of the Foundation. Terminus offers scientific support for neighboring kingdoms, balancing their powers.
|80 - 195 F.E
|Foundation develops quasi-religious sway over neighboring kingdoms. Foundation then relies more on economic influence.
|Under Cleon II, Imperial General Bel Riose campaigns against the Foundation, conquering large territories. But Cleon recalls the fleet, as predicted by psychohistory.
|Dagobert VIII rules remnant Empire. The rebel Gilmer's troops sack Trantor. Second Foundation protects the Galactic Library, then signs a peace treaty with Gilmer.
|Empire of Dagobert IX has shrunk to twenty worlds centered on Neotrantor. The Mule, a mutant with strong mentalic power, conquers the Foundation, knocking Seldon Plan off course. The Mule establishes the Union of Worlds and searches for the Second Foundation.
|Members of the Second Foundation mentalically alter the Mule, who then gives up further conquest.
|Death of the Mule. The Foundation regains strength, but also begins studying neglected mental sciences, further endangering Seldon Plan.
|The Foundation searches for the Second Foundation, fearing its mentalic rule. Diverting this search with a ruse, the Second Foundation continues operating secretly on Trantor (Star's End). Daneel Olivaw unleashes his Gaia overmind.
|The Gaia overmind offers Golan Trevize ("the man who is always right") a choice between an Empire built by physical force, one rules by Second Foundation mentalics, or a galaxy-sized version of Gaia.. Galaxia. No other options are presented and no other humans consulted. Trevize chooses Galaxia. Preparations being for gradual assimilation of humanity into the collective overmind.
|Trevize embarks on a journey, seeking to explain his choice. On Solaria he finds the planet's vanished folk have become a new race. Reaching Earth, he meets R. Daneel Olivaw, whose actions to this point were compelled by the Zeroth Law. Trevize realized any real solution must take into consideration robots, Solarians, memes, mutants, and any other kind of intelligence. The right answer may not be to simplify.
|First Galactic Coalescence Investigation Commission convenes on planet Pengia. The subsequent Great Destiny Debates rage on for 180 years, interrupted by waves of violence, amnesia, and chaos. Robotic civil ward reignite. Foundation civilization approaches ultimate confrontation with both Gaia and Chaos.
