For more on the creation of this timeline, read Geoff Johns' comments in a 2007 IGN.com interview, and more in a Newsarama interview.

Essentially, he asserted that in the post-Infinite Crisis universe:

  • "Adventure Comics #300 ... happened."
  • "...any Superboy and the Legion of Superheroes story ... happened."
  • "Really, we're sticking with everything that happened up through Crisis on Infinite Earths."
Comments Issue #
Pre-20th Century
Four billion years ago: On the planet Oa, Krona's forbidden experiment to witness the birth of creation causes the universe to split into the multiverse and unleashes a wave of evil into the cosmos. Krona is banished for his crime. His fellow Oans become the Guardians of the Universe. NOTES: This is the 1st chronological app. of the Guardians of the Universe, whose 1st app. in print was in Green Lantern #1 (7.60). (Green Lantern #40, 10.65)
A faction of the Guardians, dissatisfied with their colleagues' tactics in the war against evil, splits off to become the Controllers. NOTES: The Controllers first appeared in Adventure #357 (6.67). Their connection to the Guardians was revealed in Crisis. (Crisis #7, 10.85)
Three billion years ago: The Guardians devise a corps of warrior androids dubbed Manhunters. After the Manhunters rebel, they are disarmed and exiled from Oa. Over the coming millennia, the Manhunters secretly conspire against their former masters. (Justice League of America #141, 4.77), (Secret Origins #22, 1.88)
The Guardians of Oa organize a new force to battle evil throughout the universe: the Green Lantern Corps (1st chronological app.). The first Green Lantern is Rori Dag of the planet Rojira. NOTES: The Green Lantern Corps first appeared in Green Lantern v.2 #11 (3.62) (Green Lantern #67, 3.69)
c. One million BCE: Imsk, a planet around the star Irulan and the eventual homeworld of Salu Digby (Shrinking Violet), is colonized by the Krill. Eleven years after the colonists' arrival, they discover that the planet itself shrinks for a period of 90 days every ten years. To enable them to survive the shrinkage, an Imskian scientist finds a way to use the energies of radioactive Imskian rock to let all Imskians change their size at will. The ability is passed on to subsequent generations, but all Imskians must be exposed to the radiation once per year or they will die. (Superboy & the Legion #234, 12.77)
During Krypton's expansionist era, an astronomer named Val-Or discovered a distant sun, which was named after him. Later, a world in that system took the name of it's discoverer, Dax-Am. (They also ventured to Shwar, Imsk and Durla.) Unlike other worlds, Daxam's population melded with the colonizers'. Their genetic code was similar enough to enable mating. In time, Daxamite society grew to forget Krypton, and prosper. Some inherited the Kryptonian desire for exploration, and two camps arose: explorers and those who feared it. Superman Annual #14 (2009)
c. 5000 BCE: The native humanoids of the planet Rimbor (eventual homeworld of Jo Nah, Ultra Boy) become extinct. (Legion v.4 #15, 2.91)
1243 BCE: Searching for Universo, Shrinking Violet visits Gizeh (Giza), Egypt. Adventure #349 (10.66)
"Ancient times": A desert plague overtakes the planet Daxam. Its healing arts fall into the dark ages and the elders blame technology for failing them. When they are invaded by aliens, a scientist creates a powerful planetoid that becomes a huge golem and it topples the invaders. Superman #675 (6.08)
c. 209 BCE: The civilization of the planet Durla is nearly wiped out by a nuclear conflict called the "Six-Minute War." The inhabitants survive only through their shape-changing powers. Their original form is unknown. NOTE: The date was established by Legion v.2 Annual #2 (1983). (Legion v.2 #301, 7.83)
250–900 CE: Young Zax Vane leads a peaceful space program to Dryad, [cat-world], Xudar, Kalanor, Rann, Dhor, Korugar and Krypton itself. In this time, they discover their powers under a yellow sun. Unlike Kryptonians, Daxamites could sometimes breed with other races. This was proven by explorer Bal Gand, who visited Earth and conceived a child with an Mayan native, Juyu. Upon her return to Daxam, she kept her ship ready for return voyage, in case her family would not accept her child. The progeny of this clan were especially prone to look to the stars. For others, xenophobia grew, due in part to the Kryptonian Eradicator—which corrupted Kryptonian immunity to alien worlds and altered thought patterns. A four-day Science War eventually broke over the issue and cost a quarter of the population. Over millennia, this fostered a "pure-blood" Sorrow Cult, who feared all things alien. Over hundreds of years, their leader altered written history to omit the Science War and Krypton. Superman Annual #14 (2009)
c. 500 CE: The Guardians shrink the warrior giants called Djinn to tiny size and imprison them in bottles of green energy. (Legion v.2 #267, 9.80)

1300 CE: In pursuit of Universo, Chameleon Boy appears in the Peruvian city of Cuzco, capitol of the Inca empire, where he is nearly slain by the jealous Inca god-king. Adventure #349 (10.66)
700 years ago: Alien Athranian gene farmers abduct the Anasazi tribe and install them on a new planet. The Athranians are overthrown by the Spider Guild and this colony is forgotten. Genetic experiments endow them with wings. NOTE: This contradicts pre-Crisis lore from Legion v.2 #305, which stated that Starhaven was founded in the 23rd century. (REBELS v2 #2, 5.09)
Centuries ago: Brainiac of Colu sets out to collect all available knowledge in the universe. He uses miniaturization technology to spirit away whole cities, and destroys what remains of their worlds. Among these planets are Braal, Winath and Tharr. Action #872 (2.09)
c. 1600 CE: The island of Marzal is colonized by escaped slaves. The island fades into another dimension to return for 30-year periods every 200 years. (Legion v.2 #265, 7.80)
1812 CE: A time-traveling Saturn Girl visits Paris, where she encounters Napoleon and is nearly slain by a French aristocrat under the hypnotic control of Universo. Adventure #349 (10.66)
The radioactive boulders that renew Imskians' shrinking powers are consumed by a race of space dragons. Afterwards, the people of Imsk must periodically hunt the dragons and remove some of their scales, which emit the radiation necessary for the Imskians' survival. (Superboy & the Legion #234, 12.77)
20th Century Krypton
1938: During Krytpon's age of conquest, commander Dru-Zod's interstellar warship crashes on Earth at Texas and burrows into the planet. NOTES: This was said to have been "68 years ago," putting it in the year of Superman's published debut. "Dru-Zod" was General Zod's original pre-Crisis name. (Superman #650, 2.06; Action #838, 6.06)
Jor-El discovers the Phantom Zone, which Krypton's Science Council decides to use as a prison for Kryptonian criminals. NOTES: Adventure Comics #323 (1964), asserts that the Phantom Zone is the same dimension as, or contiguous to, the Bgztl Buffer Region. This issue was also the first historial app. of General Zod. (Adventure #283, 4.61)
Jax-Ur destroys Kandor's lunar colony. This lures Brainiac to Krypton. Jax-Ur becomes the first prisoner of the Phantom Zone. He's later joined by Quex-Ul, a surgeon who went mad with torture; Tor-An, a serial rapist and killer; and Nadeira Va-Dim and Az-Rel, homicidal lovers. NOTES: Jax-Ur's 1st historical app. was Adventure #289 (1961); Quex-Ul's, Superman #157 (1962). (Action #846, 2.07), (Action #867, 9.08)
35 years ago: The destruction of Kandor's lunar colony draws the attention of the Coluan, Brainiac. He attacks the Kryptonian city of Kandor. He seals it off, shrinks it and stores it in his ship. For his prowess against Brainiac's droids, General Zod becomes a hero. (Action #866, 8.08), (Superman: New Krypton Special #1, 12.08)
Lar Gand is born on Daxam to Kel and Marisa Gand. NOTE: The year of Lar Gand's birth in any timeline has never been established, although the 2995 Sourcebook gave his birthday as March 27. *
When Dev-Em (1st post-Infinite Crisis app.) is banished to the Phantom Zone, a riot breaks out in Fort Rozz prison and a Zone projector explodes, sending the prison into the Zone as well. Unlike the rest of the Zone, the prison is solid and time passes normally therein. NOTE: Dev-Em's 1st historical app. was Adventure #287 (1961), as a teenage delinquent whose ship escaped Krypton's destruction. He eventually became a pre-Crisis Legion ally. (Action #851, 8.07)
Jor-El and his mentor, Non, gather evidence of Krypton's declining geological health. Their lab is raided by General Zod and Ursa of the Kryptonian Defense and they are charged with heresy. The are set free, but Non continues to preach destruction and Zod and Ursa join his cause. The Council then kidnapps Non and transforms him into a mindless beast while Zod pleads with Jor-El to join them. Jor-El, however, will not choose violence and the rebels are ultimately captured again. Jor-El intercedes on their behalf; they are not executed, but banished to the Phantom Zone. Zod blames Jor-El for denying them chance save Krypton and swears vengeance on Jor-El and his son. NOTE: The first post-Infinite Crisis apps. of Zod, Non and Ursa was Action #845 (2007). (Action Comics Annual #10, 2007)
As the planet Krypton explodes Jor-El and his wife Lara prepare their infant son, Kal-El, for an interstellar voyage. Kal-El's ship is launched into space moments before the planet's destruction, bound for Earth. NOTES: Post-Infinite Crisis Superman continuity is governed by Superman: Birthright maxi-series. This series took cues from both the "Smallville" television series, the Superman movie series, and the "Legion of Super-Heroes" cartoon series, all of which show a young Clark Kent gradually coming into his powers, but never taking the name "Superboy." Part of this trend was due to legal claims brought against DC Comics by the heirs of Superboy's creator, Jerry Siegel. (Action #1, 6.38); (Superman: Birthright #1, 9.03)
A small group of Legionnaires visits Krypton on the day of its destruction. NOTES: The date of Krypton's destruction was given in World of Krypton #3 (9.79). (Legion v.2 #255, 9.79)
During Krypton's last moments, Jor-El and Lara receive a message a viewscreen sent from the future, in Lex Luthor's lab. Through the static, they see a barely-visible figure wearing the "S" insignia who says: "Mother... Father... I made it." Realizing that their efforts were successful, Jor-El and Lara kiss as the building collapses around them. (Superman: Birthright #12, 9.04)
Jor-El's brother, Zor-El, protects Krypton's Argo City using Brainiac's force field technology. The city escapes into space. When Brainiac reawakens, Zor-El and his wife Allura send their daughter, Kara, in a spaceship to Earth after her cousin Kal-El. Kara's rocket is encased in kryptonite and over 30 years, it builds in her bloodstream. When she arrives on Earth, the kryptonite causes memory loss and hallucinations. NOTES: Zor-El's 1st post-Infinite Crisis app. was Superman/Batman #9; Allura in Supergirl v.5 #16 (6.07); Kara in Superman/Batman #8; she does not become a member of this Legion. When first told, in Supergirl v.5 #16 (6.07), Kara had supposedly been sent by her mad father to Earth to kill Kal-El. She believed he was possessed by malevolent phantoms. This was "retconned" away by the tale in #35. (Supergirl v.5 #35, 1.09)
Brainiac assimilates Argo City into Kandor, then destroys Argo. (Action #869, 11.08)
The infant Iris Russell appears from the 30th century and is adopted by the West family. NOTES: Iris West and Barry Allen (Flash II) are the parents of Don and Dawn Allen, the 30th Century "Tornado Twins," and grandparents of the Legionnaire XS. Iris first appeared in Showcase #4 (10.56). Don and Dawn Allen first appeared in Adventure #373 (10.68). (Flash v.1 #350, 10.85)
Smallville, Kansas
Kal-El's rocket lands in Smallville, where he is found and adopted by Jonathan and Martha Kent and given the name Clark Kent. The boy's powers develop gradually and do not fully manifest until he is almost 18 years old. NOTES: Superman's foster parents first appeared in Superman #1 (Sum.39). Action #1 (6.38) said only that he was found by "a passing motorist." Jonathan Kent was first named in Adventure #149 (2.50), Martha Kent in Superboy #12 (2.51). (Superman v.1 #1, Sum.39)
Young Clark Kent finds his new powers increasingly troubling. He confides with Lana Lang about them. First strength and invulnerability, then x-ray and flight. A kiss from Lana ignites his heat vision. John and Martha Kent decide to show him his spaceship. He activates a holographic image of Jor-El and Lara, which he reacts against. He meets young Lex Luthor, who lives with his father and sister, and who has discovered green kryptonite. The Kents fashion a pair of glasses made from his ship that withstand his heat vision. Martha is inspired by Kryptonian fashions to make Clark a uniform using his swaddling cloths, and bearing the El family crest. Clark celebrates his birthday on December 1. (Superman: Secret Origin #1, 11.09)
Clark begins costumed adventuring but remains relatively unseen. Lex Luthor succeeds in killing his father but making it look like an accident. The three founding members of the Legion of Super-Heroes (Cosmic Boy, Lightning Lad, and Saturn Girl) travel back in time to meet their idol, Superman. Instead, they find 14-year-old Clark Kent, who is oblivious to his legend. They reluctantly allow him to return to the future with them. He visits their clubhouse in 30th century Smallville, where he meets their other members, and joins the Legion. When Clark returns to the 20th century, a Kryptonian ship crashes, delivering Krypto. NOTES: The Legionnaires call him "Clark," not "Superboy." This chronology assumes that Silver Age stories were told in the order in which Clark experienced them. This may be different than the order in which the Legionnaires experienced them. The original tale says the Legion lives in the 30th century, although some subsequent stories used the 21st century instead. Most Legion stories are supposed to take place exactly 1,000 years in Superman's future (not Superboy's). (Superman: Secret Origin #2, 12.09), Adventure #247 (4.58), (Action #858, L12.07)
The Legion tries to stop Superboy from going on a rampage, unaware that he is actually on a secret mission for the President. NOTES: 2nd Legion app. The Legionnaires' costumes are changed from their first appearance. They still use rocket belts rather than flight belts. It's unclear whether this event exists in current continuity. Adventure #267 (12.59)
When traveling across the country, young genius Lex Luthor discovers a piece of kryptonite in Smallville, Kansas. He forces his father and sister to move there. His mother died when he was young. He and Clark become friends, sharing a love of astronomy. NOTE: Lex's sister is not mentioned in Birthright, but in the next entry. Also shown in Superman: Secret Origin #1. Superman: Birthright #6-8 (3-5.04)

Lar Gand of the clan Gandaja finds references to an abandoned spaceport. He and his friend Van find his ancestor, Bal Gand's, ship near an ancient temple high in the mountains. The ruling elders of the Sorrow Cult discover him there and he escapes in a spacecraft, which is preprogrammed for a return flight to Earth. At this time, Lar's has a younger sister and his parents are ill. Asleep, Lar learns about Krypton. 1st chronological app. of Mon-El.

Superman #674 (5.08); Superman Annual #14 (2009)
Lar Gand of Daxam crash lands on Earth and loses his memory. Because of his instruction, he believes he is from Krypton. He meets the young teen Clark Kent, who intercepts Gand's rocket. Gand speaks Kryptonese and addresses him as the "son of Jor-El." Clark takes him in, hoping he might trigger information in his sunstone crystals. Clark begins to wonder if the older boy is his brother, and Lar fashions a name for himself: Mon-El. When Clark decides to test his kryptonite on him, Mon-El shrinks away from it and regains his memory. He is poisoned by the enclosing lead box and asks Clark to project him into the Phantom Zone until a cure can be found. NOTE: Action Annual #10 is one of the first verifications that Superman: Birthright was the definitive origins. It also shows new diagram of the Fortress of Solitude shows this Legion, which is the first evidence that the original Legion has been restored to Earth-0's continuity. Superboy v.1 #89 (6.61), (Action Comics Annual #10, 2007), (Superman Annual #14)
Dawnstar, Polar Boy and Wildfire travel to Smallville for a sample of young Lex Luthor's DNA. NOTES: This is just before Lex lost his hair, and after some incident involving his sister. In original continuity, Superboy first mets boy genius Lex Luthor in Adventure #271 (1960). In current continuity, their meeting is governed by Superman: Birthright #??. Final Crisis: Legion of Three Worlds #3 (12.08)
At age 18, Lex Luthor uses his kryptonite sample to fuel a device that can peer into Krypton's past. Clark is exposed to kryptonite for the first time, and Lex mistakes Clark's sudden illness for disdain. When the machine overloads, it singes off Lex's hair, destroys his home, and kills his father. Lex later destroys all traces of his life in Smallville. Superman: Birthright #8 (5.04)
The time-traveling Karate Kid meets Superboy and a group of young Legionnaires, who help him battle the Lord of Time and Major Disaster. The Lord of Time blasts Karate Kid forward in time and erases the Legionnaires' memories of these events. NOTES: The Lord of Time first appeared in Justice League of America #10 (3.62), Major Disaster in Green Lantern v.2 #43 (3.66). Karate Kid #12-13 (1-4.78)
Clark meets the new Legionnaire Star Boy. NOTES: It is uncertain how many of the Legion's appearances in the 20th century remain post-Infinite Crisis continuity. Since Clark did not go public in costume until he moved to Metropolis, these Legion adventures would have to have been covert. Adventure #282 (3.61)
A 30th century criminal posing as Sun Boy fools Clark into reassembling a Cyclops robot buried in Smallville by the Legion. Adventure #290 (11.61)
Chameleon Boy visits Clark to write an article for the Legion newspaper. Superboy v.1 #93 (12.61)

The Legionnaires deliberately remove their own memories of their true identities in a futile attempt to escape Mordru. Despite their efforts, Mordru captures them, along with Pete Ross and Lana Lang, and puts them on trial. The Legionnaires ultimately escape with the help of Dream Girl and the White Witch. Adventure #370 (7.68)
Superboy battles Mordru in the 20th century and imprisons him by burying him. He tosses Mordru's magical Blood Crystals into deep space, where they are later discovered by the Legion.

Phantom Girl, Dawnstar, and Superboy find Ultra Boy in the Bgztl Buffer Region and learn how he (in Superboy's body) became Reflecto. Superboy decides to resume participation in the Legion. NOTES: This was the Legion's last visit to the 20th century before the Crisis. After his public debut as Superboy, Clark visits the 30th century only three more times before the Crisis: Legion v.2 #289-294, 312 & Legion v.3 #11. Legion v.2 #282 (12.81)
20th Century: Metropolis
THE PUBLIC DEBUT OF SUPERMAN — BIRTHRIGHT
Clark finds an unlikely friend in the newcomer Lex Luthor. They share an interest in astronomy. Lex discovers a piece of meteor rock (kryptonite), which causes Clark sudden pain. Later, Lex opens a portal allowing him to veiw events on the planet Krypton — until his device explodes. In the resulting conflagaration, his house burns and he loses his hair. NOTE: Birthright #1 was the post-Infinite Crisis Luthor's true 1st app. (Superman: Birthright #8, 5.04)

Clark returns to Smallville, determined to learn more about his alien heritage. He convinces his mother to unearth his spaceship and he uses an alien tablet to access Kryptonian historical records. He learns of his family's "S" insignia and uses it on a costume designed for his super-powered adventures. Martha Kent encourages him to dress — while in civilian attire — in a professional but nondescript way complete with faux glasses. He develops different body languages for both his "identities." (Superman: Birthright #3, 11.03)
Clark Kent interviews for a job at the Metropolis newspaper, The Daily Planet. He meets Jimmy Olsen and Lois Lane. The editor, Perry White is unsure of his ability to pursue a story aggressively enough.

Jor-El and Lara also appear, seconds after launching their son. (#12) NOTE: Issue #12 asserts that Clark only just learns his name, Kal-El, from Luthor's viewscreens, but in Action Comics Annual #10, Clark is a boy and already knows his name of Kal-El. Since Birthright was not necessarily meant to rewrite Superman's at the time of its publication, I defer to latter-day tales for definitive answers. (Superman: Birthright #10-12, 7-9.04)
The public debut of the Flash II, Barry Allen. Showcase #4 (9.56)

A single universe arises out of the battle at the Dawn of Time. NOTE: The full effects of the changes to history did not appear for several months afterward.

The survivors of the battle at the Dawn of Time awaken on Earth, which has been unified to include aspects of Earth-1, -2, -4, -S, and -X (only those who were present at the Dawn of Time remember the multiverse). Earth-2 heroes including Superman, Robin and the Huntress, discover that they were never born in the reformed universe. Earth is then drawn into the anti-matter universe, where the Anti-Monitor prepares to destroy the Earth once and for all. NOTES: This issue began an "interregnum" period in which the previous multiverse had been united into a single world, but during which most of the changes later attributed to the Crisis (such as the extensively revised histories of Superman and Wonder Woman) had not yet appeared and those who were present at the Dawn of Time still remembered the multiverse.

Alexander Luthor (of the former Earth-3) receives visions of a "paradise" and a "hell" which are his only two options to escape the disintegrating antimatter universe. He does not realize that the hell is Apokolips, and his vision is linked to Darkseid's. He decides upon the extra-dimensional "heaven," but is left much weaker he does not have enough power to escape it. As they adjust to life there, Alex regrets not choosing to Apokolips, because they could have returned to Earth. He also resents having grown to adulthood in a matter of days, wishing that Superman had saved the world instead and allowed him a normal life. Ultimately, Alex's bitterness overcomes him and he begins coercing Superboy into pummeling their crystalline barrier. He finds that the unified Earth has not settled into its proper place and each blow alters its history. Alex is convinced he can create the perfect Earth and begins an elaborate plan. NOTES: Superboy Prime's blows ultimately create the Legion of Earth-Prime, and alters Superman's history, too. Crisis #12 (3.86), Infinite Crisis Secret Files (4.06)
