2064 , AD : Death of Susan Calvin
2070-3200 , AD : Extrasolar colonisation begins on several planets including Aurora.
First Chaos outbreaks affect humanity, breaking down confidence.
The aftermath of the Chaos Plagues on Earth cause Terrans to build underground hive-cities.
On Earth Robots are banned from cities.
Aftermath of Chaos Plagues on colony (Spacer) worlds cause colonists (spacers) to loose empathy.
Relations between Earth and Spacer worlds decline
3200-3500 , AD : The last Spacer world, Solaria, is settled by the Spacer world Nexon.
Decline of the Robot-Dependant Spacer culture begins.
Dr Han Falstolfe of Aurora begins work on humaniform robots
3470 , AD : Spacetown (a Spacer enclave) is established near New York City prompting xenophobic anti-Spacer and anti-Robot riots.
3500 , AD : R. Daneel Olivaw is assigned to work with Terran investigator Elijah Baley to investigate the murder of a prominent Spacer in Spacetown (in The Caves of Steel).
3501 , AD : Elijah Baley and Daneel Olivaw pursue a murder investigation on Solaria (in The Naked Sun).
Dr Han Falstolfe enters politics in the Auroran government, he pursues a pro-Terran policy.
Opponents of Falstolfe led by Kelden Amadiro seek to promote an expansionist policy of terraforming and populating new planets.
3503 , AD : Elijah Baley carries out investigation on Aurora accompanied by Daneel Olivaw and Giskard Reventlov, a telepathic Robot (in Robots of Dawn).
Aurora lets Earth begin an expansionist programme
Giskard advises Elijah that the new Settler worlds must be completely Robot-free.
3505 , AD : Second (Settler) wave of emigration begins led by Ben Baley. First Settler planet is named Baleyworld.
3537 , AD : Death of Elijah Baley on Baleyworld
3537-3696 , AD : Number of Settler worlds grow fast resulting in tense relations between Settlers/Earth and Spacers
3696 , AD : Kelden Amadiro and Levular Mandamus begin planting nuclear amplifiers througout Earth to take revenge for their political defeat which had resulted in the the permission for Earth to found colonies.
3700-3800 , AD : Death of Dr Han Falstolfe.
Population of Solaria vanishes
Daneel Olivaw and Giskard Reventlov formulate the 0th Law to override the Calvinian 3 Laws for the greater good of humanity as a whole.
Giskard provides Daneel with telepathic abilities.
Amadiro turns on nuclear amplifiers that will make Earth uninhabitable. Giskard permits this for 0th Law reasons as it will encourage the expansion of humanity. Giskard promptly dies as this will also cause the death of millions, a fact that is unquestionably against the 1st Law.
3801-3855 , AD : Spacer world Inferno is doomed by ecological breakdown as well as the general Spacer cultural decay. Settler terraforming specialists are brought in to stabilise the environment. Robots are built with weakened 1st Laws to allow them to work with humans in the risky re-terraforming project.
Hostility to New Law robots grows
As part of the re-terraforming project it is proposed that a comet is manoeuvred to skim the atmosphere of Inferno. Political terrorism causes potential oblivion as result of cemetary impact, this is narrowly avioded, primarily as a result of actions by a small number of robots. The crisis results in merging of Spacer and Settler populations on the planet
3800-12000 , AD : As a result of Giskard's actions the Great Diaspora also called the First Dark Age begins.
The majority of robots are split into two camps. Giskardians, led by Daneel follow the new 0th Law 'religion'. Calvinians who follow the tradional 3 Laws see this as an outrage. Robotic civil war ensues, mostly unseen by humans.
Robotic ships operating under Auroran programming are launched to prepare planets for a planned colonisation by Spacers, a project that never takes place due to social conservatism. Later evidence will imply that these ships obliterated millions of low tech races through high powered mazers used for producing topsoil during terraforming.
At an unknown point the robotic war reaches Inferno and the New Law robots are largely destroyed, though some manage to go into hiding.
Spacer worlds stagnate and eventually die out Daneel places mental broadcasters (Giskards`) around each Spacer world to prevent rediscovery of Spacer tech/society.
Settler worlds spread througout the galaxy, falling into feudal government structures and forming principalities and kingdoms.
Settler world Rhodia and the Nebular Kingdoms led by the Noble Hinriad family manage to shake off rule by the Tyrann Kingdom and in the process redescover democracy (in The Stars Like Dust.
Damping effects such as historical amnesia, brain fever and use of orbiting mind control devices (Giskards`) are introduced by Daneel to fight the re-emerging Chaos Plague. Some Calvinians and Humans (notably the Nebular Kingdoms) fight the amnesia. Nebular kingdoms have to admit defeat but manage to broker a deal with Giskardians: Nebular kingdoms will be left alone in return for them not interfering in the rest of the galaxy
12000-12300 , AD , The Trantorian Republic of five worlds goes on the offensive, renaming itself the Trantorian Confederation and later the Trantorian Empire. R. Daneel uses his basic grasp of the laws of humanics` to guide it and steer it away from Chaos. in the process human origins are forgotten. By 12300AD half of the inhabited worlds of the galaxy are part of the Trantorian Empire, other states are forced to look to Trantor when conducting their affairs example being the rebellion of Florina against the Sark Kingdom in 12300 (in the Currants of Space)
12500AD/1GE , - , Trantor declaires itself the Galactic Empire and begins the Galactic calendar (GE)
827 , GE , Arrival of Joseph Schwartz (thrown forward from the early 21st Century AD. A now radioactive and sparsely populated Earth tries to revolt against the Empire by using a bio-weapon. The rebellion fails, partly thanks to Schwartz with the use of a mentalic amplifier. Schwartz travels the Empire`s core worlds campaigning for aid for Earth. He comes to the attention of the Emperor who reacts favourably and provides shipments of non-radioactive soil This effort is mysteriously abandoned
c900 , GE , Forced evacuation of Earth. Establishment of a colony of the Earth refugees on planet Alpha.

11867 , GE , The only extragalactic human colony, in the Greater Magellanic Cloud is abandoned. All data on the project is suppressed
11988 , GE , Birth of Hari Seldon and of Cleon I. Daneel is aware that the Empire is destabilizing, partly due to the explosion of 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 finally succede in producing one man (Seldon) who is immune to the Chaos Plague and the Brain Feaver as well as showing amazing talents for mathematics. Separate projects at this period lead to the isolation of those genes which allow the use of mentalic abilities.
12010 , GE , Cleon I becomes Emperor
12020 , GE , Hari Seldon lectures at a mathematics convention on Trantor about the possibility of predicting broad social trends through mathematics. He calls this hypothetical study Psychohistory`. This is misunderstood by the Emperor to mean that Seldon can predict the future, making Seldon a dangerous man. Daneel extracts Seldon from the attentions of the Imperial security services and convinces him to attempt to develop a practical predictive science to save the Empire. Seldon marries Dors Venabili and they adopt a son, Raych. Seldon and fellow mathematician Yugo Amaryl begin to flesh out Psychohistory.
12028 , GE : Calvanian robots, led by R. Plussix, move to Trantor and find historical documents dating from the era of Shoree-Harn including AI simulations of Voltare and Joan of Arc They help to seed a new Renaissance` on planet Sark.
Seldon helps remove the radical Laskin Joranum from politics. Daneel (aka. First Minister Demerzel) resigns his post. Cleon I (under Daneels influence) appoints Seldon as First Minister
Voltare and Joan get into the Trantorian Mesh (read super-high speed/complex/big internet) where they meet ancient and sentient memes and trigger a rebellion among the primitive tiktok` robots which had recently been developed on Trantor. The ticktoks proceed to hunt out and kill Daneel's humaniform companions. Seldon manages to strike a deal that gets the memes off Trantor (in Foundation's Edge).
The Sark renaissance falls into the Chaos phase.
12038, GE : Cleon I dies and a military junta seizes power prompting Seldon to retire from politics to spend more time with is formulas (in Dors Venabli)
12040, GE : The Chaos Plague strikes the renaissance world of Madder Loss. The apparent rise and collapse of this vibrant world rocks the galaxy.
Wanda Seldon daughter of Raych is born, she later (12052GE) is discovered to have powerful mentalic abilities.
12048, GE : 'Death' of Dors Venabili and the fall of the military junta (in Dors Venabili). The 'Commission for Public Safety' takes control of the Empire through the manipulation of the puppet Emperor Agis XIV.

Planet Ktlina experiences a great renaissance which rapidly decends into Chaos.
Mors Planch enters a time warp (a result of the events in Pebble in the Sky) to the year 12588GE (in Foundation's Triumph by David Brin).
A truce is called in the ongoing war between the Calvinian and Giskardian robots. They agree to find a single human who is untainted by robotic manipulation, a 'man who is always right' decide humanity's fate. Until that man is found they will cease the conflict.
12069 GE / 3FE : Death of Hari Seldon. Psychohistorians cause secesion on the rim (described in The Organist).
12116 GE / 50FE : Anacreon declaires independance from the Empire. This isolates Terminus and the Encyclopedia Foundation.
The hologram of Seldon appears to reveal the true purpose of the Foundation, that it is to create a Second Galactic Empire.
Terminus offers scientific support to neighbouring Kingdoms, managing to balance their powers and play one against the other (in The Mayors)
80FE-195FE : The Foundation follows a policy of playing to the increasing superstitious natures of the surrounding kingdoms but later switches to a policy of economic manipulation.
195FE : The campaigns of Bel Riose, the last great imperial leader. Riose manages to retake vast territories, but Riose is recalled to Trantor along with the Imperial Fleet amid fears of his growing prestige (described in The General)
c260FE (12327GE) : The Fall Of Trantor. The Empire of Trantor has shrunk to a remnant of the core worlds. Under the Emperor Dagobert VIII civil war breaks out. The rebel leader Gilmer leads his troops through the remains of the world city and sacks the former galactic capital. The Second Foundationers protect the Galactic Library before signing a peace treaty with Gilmer.
c300FE : The Mule, a powerful mentalic uses his abilities to conquer the Foundation and establish a 'Union of Worlds'. He then begins a search for the Second Foundation.
By this point the former Galactic Empire has shrunk to just twenty planets ruled from Neotrantor under the Emperor Dagobert IX.
305FE : The Mule is mentally altered by Second Foundationers so as to force him to abandon his dreams of galactic conquest. He dies five years later. The Foundation has learnt it's lesson and now begins studying the field of psionics.
498FE-499FE : Councilman Golan Trevize and Professor Janov Pelorat of Trantor begin their search for the Second Foundation and for the mythical mother world of Earth. After many events they are guided to Daneel's experiment; Gaia. Trevize (the 'man who is always right') is presented with the choice that will decide the future of the Galaxy: does he want the First Foundation to rule through force, the Second Foundation to rule through manipulation or does he want a mental union of humanity in the style of Daneel's Gaia, a Galaxia? Trevize chooses Galaxia. Trevize and Pelorat then continue their quest to discover Earth, in the process landing on a number of Spacer worlds. They eventually locate Earth and meet R. Daneel Olivaw.
520 FE : First Galactic Coalescence Investigation Commission meets on Pengia. The implications of this are unclear.
