Since all of this information has come from other sources, I don't feel as though I can copyright it. Feel free to use it as you wish, within the bounds of other copyrights on this material. If you like the occasional hypothesis that I have left strewn about within, please recall where you found it.

Notes on sources:

The sources used for this were Larry Niven's stories and novels. Some details from the Ringworld Game by Chaosium were added as well, and are noted as such.

The codes in parentheses indicate the source.

The above materials will be superseded should different information be published.

Finally, all items marked with an * are conjecture, based on the information on hand, and may be further explained by a description in brackets.

I would like to point out that noting the inconsistencies between dates should not be construed as criticism.  I'm happy that things hang together as well as they do.

It should be noted that the dates of the Gil Hamilton stories are absolutely internally inconsistent.

This material is in no way official, and the last time I heard had not received any "OK" from Niven.  I've never met the man, and have no insight into his writings other than what you see here - so please stop asking me how to contact him.

But I digress...

The Chronology

about 15 Billion Years Ago

Creation of the Universe (Ya gotta start somewhere!).

about 10 Billion Years Ago

Galaxies form.

about 9 Billion Years Ago

The "Outsiders" watch as planet-based sapients begin to develop (MKW7 "A Darker Geometry" - n.b there is some debate on the canonicity of this story).

about 1.5 Billion Years Ago

The Thrint, later known as the "Slavers", rule the Galaxy (This is described as anywhere from 1.5 to 3 Billion years ago).

The crypto-Ptavv Guerdoth's Pruntaquilan Balladeer Coquaturia is hidden in a stasis box (MKW5 "Hey Diddle Diddle").

In the last decades before the end of their rule, the slaves of a Thrint named Plorn produce antigravity, ruining the need for Stage Trees to launch material, and precipitating a major economic crash (World of Ptavvs, "A Relic of Empire").

At this point, Kzanol experiences a failure of his ship, which he abandons. He aims it at the eighth world of F124, and places himself in stasis. His ship slams into a moon orbiting the eighth world, tearing the moon from its orbit and forming the planet later called Pluto. Kzanol slams into the algae-covered sea of F124 - III, later known as Earth (World of Ptavvs).

Before Kzanol actually impacts onto Earth, the Thrint Empire is engulfed in a civil war that will last for a century. This long revolt is led by the Tnuctipun, using their weapons of Sunflowers, and their Bandersnatchi / Whitefood spies. This war quickly involves all known species in the Galaxy, presumably excepting the Outsiders (World of Ptavvs, "The Soft Weapon").

As it becomes clear that the war is lost, the surviving Thrint build a giant telepathic Amplifier designed to order all sentients in the Galaxy to commit suicide on "Last Day" (World of Ptavvs, MKW3 "The Asteroid Queen").

Durvash the Tnuctipun spy discovers a way to halt the impending Suicide Time, but his ship is thrust into Stasis by the impact of a Thrinti Godfist weapon that imbeds the tnuctip vessel into the molten crust of what will someday become the Jotun Mountains of Wunderland (MKW5 "The Hall of the Mountain King").

A day or so before the Last Day/Suicide Time/Suicide Night, Dnivtopun, Overseer of a food world in the 7-1Z-A (Alpha Centauri) System, his wives and his young son, suffer an accident that seals them in a stasis field (MKW3 "The Asteroid Queen").  (MKW10 "Peter Robinson" appears to date this as 3 billion years ago).

Apparently some Thrint arks and colonies emerge from stasis from time to time.  None of these appear to survive very far into the future without the support of the Tnuctipun (MKW10 "Peter Robinson"). 

Somehow, some Thrintun may have survived and gradually evolved into the sessile Grogs of Down ("The Handicapped".  It should be stressed that this is a risky hypothesis since the Thrint with the Power were male, and the females were non sentient, while with the Grogs, the situation is reversed). 

about 50 Million Years Ago

The evolution of the Pak, progenitors of the human race, on the Pak home world near the core may take place about this time (Game).

about 3 Million Years Ago

Oldest date of Pak records of spaceflight in the Library  (Protector).

The planets of  nearby stars are are "Pak-formed" and then destroyed in the endless war (Ringworld's Children).

A hollowed out asteroid containing 72 protectors and a 1000 breeders leaves the Pak home world heading for the galactic arms (Protector. According to the game, this is 5 million years ago) .

about 2.5 Million Years Ago

After a half million trip. The "Earth-Pak" arrive on Earth. They discover that the Earth's soil will not support the "tree of life" root, and send a message back to the Pak home world  (Protector).   At some point after this, the surviving protectors gradually die off, leaving the Pak Breeders to evolve freely  (It should be noted that it was Brennan who made the claim that the Pak were what we would term "Homo Habilis", but Brennan wasn't an anthropologist, and there is plenty of evidence of hominid existence on Earth prior to 2.5 Million years ago.  This means that the final answer to the link between Humans and Pak has not been revealed - MC).

about 1, 024,500 BCE

At some point, after receiving the message from the "Earth-Pak" fleet, the Ringworld Builders leave the Pak home world in a fleet made up of 10,000 Protectors in fighter scouts and an O'Neill environment full of breeders (Game, Ringworld Engineers have this at 2.5 million years BCE, while Ringworld's Children describes this as 4 million falons ago).

about 1, 024,420 BCE

80 years after the launching of the Ringworld Builder fleet, there are only 600 Protectors left (Ringworld's Children).

about 936,607 BCE

Building and stocking of the Ringworld from a System with a close in Super Jovian planet  (Game, Ringworld's Children has this as being "after 350,000 falans of travel").

Before the Ringworld is completed, 11 Protectors rebel, and are imprisoned on the Maps of Pak in the Isolation Zone in the farther Greater Sea (Ringworld's Children).


At some point after the rebellion of the 11 Protector Rebels someone travels to Earth to collect Whales (and who knows what else) (Ringworld's Children).

about 883,000 BCE

The Pak system on the Ring may have broken down about this time ("A few hundred thousand" falons after Creation Ringworld's Children).

about 513,698 BCE

Species differentiation begins on the Ring, suggesting some breakdown of  the Protector system (1 million falons before Ringworld's Children).

about 500,000 BCE

Puppeteer population numbers nearly half a trillion. They terraform two of the worlds in their system (Ringworld).

about 250,000 BCE

Approximate age of the "Map of Earth" on Ringworld (Game).

The Ringworld Pak die off from some undisclosed disease (Ringworld Engineers. Game has this at 300,000 BCE).

253,956 BCE

Proserpina has been "trapped" at least this long (1 million falons before Ringworld's Children).

about 100,000 BCE

"Outsiders" help the Puppeteers with technologies. They sell them gravity planers, hyperdrive, and the "Mover of Worlds" (MKW7 "A Darker Geometry" - n.b there is some debate on the canonicity of this story).

53,000 BCE

On Pak, the childless Pak Protectors gather for war (Protector).

about 40,000 BCE

"Cathouse" world built and stocked (MKW1 "Cathouse") (It's really not clear by whom, since the Ringworld Pak Protectors are supposed to be dead by this time.  There are sentient Kzin females and telepathic Neanderthal).

33,000 BCE

Phssthpok leaves the Pak home world (Protector).

32,800 BCE

First Emigration Wave leave Pak home world, following up on Phssthpok's flight (Protector - Truesdale's estimate).

32,500 BCE

Second Emigration Wave leaves Pak home world (Protector - Truesdale's estimate).

32,000 BCE

Protector Scout fleet leaves Pak home world (Protector - Truesdale's estimate).

about 15,000 BCE

The Empire of the City Builders begins to spread across the face of the Ringworld (Game).

about 14,975 BCE

The Proto-Ghoul Louis Wu eventually names Cronus becomes a Protector.  He begins to direct the breeding of the Night People so that they can communicate across the Ring (Ringworld Throne).

about 8,000 BCE

Importation of species to the Ringworld by the City Builders (Game).

*The Core Stars begin to explode ("At the Core").

The Kzinti develop a fairly stable, homogenous civilization (MKW8 "Jotok"; some 5 squared to 5 cubed generations before the Jotoki arrive).

Jotok merchants visit the planet Kzin, in the 61 Ursa Majoris system. The "Mage-Kzin" appropriate technology from them, and begin to unify their world.  Some "prides" become marginalized, but remain unconquered ("Mage Kzin" females are intelligent and fight and duel like males, although this is doubted by some members of the Ritt pride)  The Jotoki attempt to hire the Ritt Pride (and likely other marginalized Kzin) as mercenaries against other Kzin, but are themselves enslaved (MKW8 "Jotok") The Kzin use the Jotoki biological sciences to drive their females into non-sentience, and to make all their males into the ideal "Heroes" (MKW3 "Asteroid Queen"; date is an estimate)   (Kzin are sometimes pluralized as Kzinti.  Both forms appear to be correct).

about 7,000 BCE

The Core Stars complete their 'orgy of self-destruction' ("At the Core").

about 2200 BCE*

The Protector eventually killed by Bram and Anne is at least this age ("tens of thousands of falans old" - Ringworld's Children).

about 1042 CE

The Vampires that Louis Wu will eventually name Bram and Anne are "shaped", becoming Protectors after feeding on the blood of a Protector ("7200 falans ago") (Ringworld Throne).

about 1094 CE

The Protectors Anne and Bram  take control of the Repair Center.  "Fist of God"  mountain is created by a giant impact from outside the Ring ("7000 falans ago").  They kill the Cronus and Anne leaves Bram at the Repair Center ("just under 7000 falans ago") (Ringworld Throne) (Apparently Louis has trouble doing math in his head - he says this is about 1200 CE, however if a Falan is 75 30 hour days long, the math is pretty clear).

about 1607

The Protector Anne returns to the Repair Center to get more Tree of Life. She leaves again shortly thereafter ("5000 falans ago") (Ringworld Throne).

1731 CE

Puppeteers introduce Superconductor Plague to the Ringworld (Ringworld Engineers. Games this date as both 1733 and 1140).

1733 CE

Superconductor Plague causes the "Fall of Cities" on Ringworld (Ringworld Engineers, "Ringword Throne". Game dates this as both 1733 and 1140).

about 1850

Kzin occupy Warhead, in the p Eridani system, because of its nearness to the unconquered Pierin worlds (Ringworld Engineers; exact date is unknown).


The "Vaughn Tiger Man" is killed by Cpt. Henry Vaughn of the 4th Lancers in Dirragha (MKW7 "The Colonel's Tiger").


Karl Landsteiner classifies blood into four types, allowing for the first safe blood transfusions (Reality; "The Jigsaw Man").


Lucas Launcelot Garner is born (Protector).


Karl Landsteiner and Alexander S. Weiner report on the Rh factor found in blood (Reality; "The Jigsaw Man").


Blood banks are found world-wide (Reality).


The Kzinti conquer the Pierin (Game date).

India begins to break up criminals for organ transplants (Reality).


Persephone (Sol X) is deduced by gravitational perturbations (Protector).


The Viking landings on Mars (Reality).


Organ transplants are common (Reality).

about 1983

Messenger VI probe visits Mercury and discovers life ("Coldest Place").


Persephone (Sol X) is first seen by Earth astronomers (Protector).

about 1985?

"Howie" and Eric Donovan's brain visit both Mercury and Venus ("The Coldest Place", "Becalmed in Hell". Date is a guess. It is likely that Eric is founder of the computer company known as Donovan's Brains in the 26th century; he might also be the "Eric the Cyborg" mentioned in the the Game section on The Belt).

Mariner XX flyby of Pluto (Protector. Date is a guess).


First laws are enacted prohibiting organ sale (Game).


It becomes legal to freeze people who are not yet legally dead ("The Defenseless Dead").

The first manned expedition to Pluto ends in disaster, trapping the lander in the Ice. Both of the crew on Pluto commit suicide by exposure to the frozen "atmosphere" ("Wait it Out").


It becomes possible to store any organ for any reasonable period of time. The dying regularly will their organs to Organ Banks ("The Jigsaw Man").

The "Project Gulliver" automated Mars Rovers land on Mars (Game).


Leviticus Hale becomes the first person frozen for a non-terminal disorder (incurable paranoia) ("The Defenseless Dead").


Vermont enacts the first Organ Bank Laws to freeze criminals for crimes (This appeared once as "Arkansas").

Louis Wu's initial estimate of when Fist-of-God mountain was created  ("3500 falans ago"). He is mistaken (Ringworld Throne).


20 July:
First manned landing on Mars (Harry Bedrosian, Christopher Luden (Lander), Abe Cooper (Orbiter)). They discover the remains of a Martian ("Eye of an Octopus" - Date given in Game).


World Convention establishes a World Government. The ruling body is called the "United Nations". Subsequently, the U.N. establishes the Amalgamated Regional Militia (ARM) as its police force (Game).

about 2000*

Logically there must be a Second Mars Expedition between the First in 1996 and the Third in 2040.  It has been suggested that this might be the Mars expedition mentioned in "The Hole Man", although this is probably not a Known Space story.  If it is, then after "thirty years of Mariner Missions" 14 crew members arrive aboard the Percival Lowell, and find an alien base that was studying Earth during the last Ice Age, as well as a quantum black hole.  The mission ends with a tragic death and Mars threatened by a black hole.

about 2007

Moon is colonized; Jacob Hovestraydt founds Hovestraydt City ("Patchwork Girl". Dates in "The Girl in Del Rey Crater" suggest c. 2030).


First orbital passenger vessel is launched (World of Ptavvs).

Sometime between 2015 and 2025

Valerie Van Scopp Rhine is born in Winnetka, North America ("The Girl in Del Rey Crater").

about 2040

The Third Mars Expedition's problems begin when John "Jack" Carter (Ecologist) murders Lew Harness (Communications) because of perceived homosexual advances. Carter is tracked to his death by Alf Harness (Linguist), the murdered man's brother, but Carter's death is bought at the cost of Alf Harness's life ("How the Heroes Die").

The remaining twelve (Lieutenant-Major "Mayor" Michael Shute; Rufus Doolittle (Biochemist); Gondot, Lee Cousins (Writer), Hurley (Cook), "Timmy", and seven others) all die when their dome, "Bubbletown" at Lacis Solis, is destroyed by Martians ("At the Bottom of a Hole").


Maxim Yeltzin Shreve is born Outer Soviet, Moon ("The Girl in Del Rey Crater").

about 2045

Boeing Corporation stops launching radioactive waste into Del Rey Crater, on the Moon ("The Girl in Del Rey Crater").


First colony ships leave for Alpha Centauri (Game).


Ramscoop Robot No. 4 discovers Plateau in Tau Ceti system.


Confinement Asteroid is completed. This enables women in the Asteroid Belt to give birth without returning to Earth. Sometime after this, the Belt becomes independent from the Earth; most of the planets and asteroids are under the Belt jurisdiction - including Earth's Moon - but Earth has jurisdiction over Mars (World of Ptavvs, "At the Bottom of a Hole").

about 2065

Ramscoop Robot No. 9 discovers We Made It in Procyon system.


Geraldine Randall born Clavius, Moon ("The Girl in Del Rey Crater").


Lucas Garner resigns as Superintendent of Police of Greater Los Angeles, and becomes an ARM ("Intent to Deceive"). He is replaced as Superintendent of Police of Greater Los Angeles by Lloyd Masney.

about 2075

Approximate date of the launch of the Lazy Eight I to Sirius (Date is my guess, however, it is mentioned as having reached Jinx by 2097 in World of Ptavvs, based on speed of Slowboat in A Gift from Earth).

about 2076

Approximate date of the launch of the Lazy Eight II, eventually lost with its 50 passengers and 4 crew, en route to Sirius ("Flatlander". Date is my guess, however, it is mentioned as having reached Jinx by 2097 in World of Ptavvs, based on speed of Slowboat in A Gift from Earth. It is possible that there were some people who escaped the runaway slowboat?).

about 2080

Slowboat launched towards Alpha Centauri (Date is estimated, based on speed of Slowboat in A Gift from Earth).


Planck launched towards Tau Ceti (A Gift from Earth. Based on launch date; trip is thirty years long).


Valerie Van Scopp Rhine becomes a full partner with Maxim Yeltzin Shreve in Gabriel's Shield ("The Girl in Del Rey Crater").

Warren Lewis Knowles is tried for excessive speeding ("The Jigsaw Man" - Date given in TKS).

about 2100

By 2100, the Belt population is about one million. This is the era of Four-Gee Jennison, Airlock Atwood, and Monopole Mike - the exploits of Eric the Cyborg and the hazardous journeys of the Ringjammer take place at this time. The Church of Rodney sells gullible Flatlanders phony mineral rights on phantom asteroids (Game).

2094 or 2099 or 2101 or 2105

"First Big Slowboat" launched towards Alpha Centauri, carrying a large scale Shreveshield (Presumably this is a much larger slowboat than the ones launched around 2060 and 2080).  ("The Girl in Del Rey Crater" says this happened when Gil Hamilton was eight years old, but his age and date of birth varies from story to story).


First Conference to Review Lunar Law. The Moon becomes the center for criminal trial proceedings and executions for the entire Solar System off Earth ("Patchwork Girl").

They both steal ships and flee first to Neptune, and then to Pluto. After igniting the entire surface of Pluto, Kzanol is sealed in stasis. His second suit, with its telepathic amplifier is dumped into the atmosphere of Jupiter. Greenberg determines that Bandersnatchi are intelligent (Lucas Garner is 170 years old at this time, and Charles Martin "Lit" Shaeffer is First Speaker of the Belt Political Section).


Free Belt Charter proclaimed (Game date? This is quite inconsistent - see 2065).

about 2110

Launch of the Lazy Eight III towards Sirius (presumably carrying Larry Greenberg).


A Ramscoop Robot discovers Silvereyes (Beta Hydri). A power outage at the Copernicus Dome (hospital and penal complex) on the Moon ruins half the organs from four executions ("Patchwork Girl").

The Serpent Swarm is colonized by Belters about this time (MKW2 "Children's Hour").

Kenneth Graham becomes a wire-head pusher ("Death by Ecstasy" dates).


A Belter, Muller, crashes on Mars, near the Lacis Solis ruins, while smuggling monopoles. He discovers that the Martians had wiped out the 3rd Martian Expedition and are still around.

Cubes Forsythe's ceremonial drunk on Ceres ("Death by Ecstasy" - presumably after Hamilton is released from the hospital).

Six months later, Gil Hamilton returns to Earth and becomes an ARM (If Hamilton's dates in "Death by Ecstasy" are accepted. He spent three years in a the belt with Owen "Four Gee" Jennison and Homer Chandrasekhar. Owen saved a meteor which had hit him in the chest. But the story "ARM" would suggest he joined in 2122).


Miranda Mitchison is killed by her father, comedian "Ich" Mitchison ("Patchwork Girl").

Naomi Mitchison visits the Moon ("Patchwork Girl").

6 September:
Naomi Mitchison applies for Lunar Citizenship ("Patchwork Girl").


First Freezer Bill passed, making it legal for people who are technically dead when they were frozen to be broken up for the Organ Banks, if they would be unable to support themselves if awakened. Twelve hundred thousand people are broken up for the Organ Banks. Most of these are "The Freezeout Kids", young people who are unable to adjust to the world they lived in and chose the frozen sleep ("Defenseless Dead").

about 2175

Earth has to "restart" the gulf stream to combat an Ice Age ("Ghost"; exact date is unclear).  


An ice asteroid is discovered by Mahmed. It crashes into Mars, most likely destroying any surviving Martians (Protector; Game gives this as 2293, and the asteroid's name as Mahrem).
