What follows is a complete Fallout timeline of all events from every game.
Note that the Fallout world is not our own, but rather one that has diverged from ours soon after World War II. So, while it takes place in the future, it is not our future, but a future as imagined in traditional 1950s science fiction. Note that the timeline is only for the chronological sequence of the Fallout world events, birthdates are not allowed here and must be put in the birthdates page.
Behind the scenes
Much of the following text comes from the timeline in Fallout Bible 0, written by Chris Avellone, which in turn comes from the original Fallout timeline created by Brian Freyermuth and Scott Campbell. Some post-Fallout information was laid out by Rob Hertenstein, and some dates were added by Chris Avellone himself. Additionally, this timeline includes all dates seen or mentioned in Fallout, Fallout 2, Fallout 3, Fallout: New Vegas, Fallout Tactics and Fallout: Brotherhood of Steel, in all Fallout official game guides, in the Fallout Bible as well as Van Buren design documents.

- July 27: The United Nations is officially disbanded.
- ZAX 1.0 goes online, developed by Vault-Tec. Initially a prototype of some of the systems designed to govern the vaults, it is given to the government to help the Department of Energy collect resource data.

The project, financed by junk bonds, is designed to create shelters, called Vaults, for the populace in the event of a nuclear war or deadly plague. Construction begins late in 2054 and proceeds rapidly due to advances in construction technology.
- ZAX 1.0 goes on-line, developed by Vault-Tec. Initially a prototype of some of the systems designed to govern the vaults, it is given to the government to help the Department of Energy collect resource data. Within a year, it is taken by the military for plague and tactical research; one version, ZAX 1.2 is constructed for West Tek.
- West Tek starts working on a new virus to kill the New Plague. Their viral research and close ties to the federal government eventually lead to them being chosen for the Pan-Immunity Virion Project twenty years later as well as power infantry armor and laser research.
- ZAX 1.2 is brought in to regulate conditions in West Tek. It is not part of the Vault-Tec preservation software, so it does not have any orders to protect humanity after the bombs fall. In the meantime, it calmly calculates data and plays chess with the scientists. Many scientists claim that ZAX is a "big ol' cheater" and draws the game out too much for a computer of his considerable abilities.

The Anchorage Front Line causes tensions between the United States and Canada, as the United States attempts to pressure Canada into allowing American military units to guard the Alaskan pipeline.
- The first artificial Intelligence is born. Limited by memory constraints, its expansion is rapidly halted. The discovery paves the way for future A.I. research in laboratories throughout the United States.
- Traffic on the streets of the world stops moving. Fuel becomes too precious to waste on automobiles, so alternatives are explored - electric and fusion cars begin to be manufactured, but factories can only make limited amounts while conserving fuel. The U.S. economy teeters on bankruptcy. Pressure on fusion research increases.
- The European-Middle Eastern War ends as the oil fields in the Middle East run dry. There is no longer a goal in the conflict, and both sides are reduced almost to ruin.

- August: The construction of most Vaults completed, except for Vault 13, whose construction finally gets off the ground heralding a development cycle that seems plagued with problems. Drills begin in the other cities with completed Vaults, but the increasing frequency of the drills has a "cry wolf" effect, and the turnouts for drills trickle off as the years go on.
- Van Buren (not confirmed as canon) The Reservation is given orders to research and produce nuclear missiles that can be fired from an orbiting space platform.
- February: Construction of Vault 76 begins.
- April 14: M.A.R.Go.T. enters service.
- June: Due to enormous demands for electricity from a 17+ million population, a nuclear reactor in New York City goes supercritical, almost causing a meltdown. The near meltdown brings into effect power rationing, and the term "Hot Summer" is used to refer to this incident.
- August: Increasing need for mobility in the United States mechanized cavalry leads the military to focus the efforts on creating a man-based tank - essentially, a two-legged walking armored unit: power armor. Research grows until 2067 and several prototypes are developed, many of which prove to be unworkable in the field. These prototypes pave the way for future advances in military, construction, and fusion technology.
- The U.S. Navy missile cruiser USS Ebon Atoll is accidentally sunk by the U.S. Navy Submarine USS. Interference during the Anchorage Campaign. The Interference mistook the Ebon Atoll for an enemy vessel and shot it with a nuclear torpedo killing all on board. It is one of the worst U.S. Navy disasters since World War II.
- Van Buren (not confirmed as canon) Resource rationing in Denver causes riots. Midwest U.S.A. and Mexico start having food shortages and can't supply Denver with the food it needs. Food riots occur. National Guard called in.

Nearly eleven years later, few sections of the United States were supplied with fusion power.
- Winter: In the winter of 2066, China invades Alaska. The Anchorage Front Line becomes a true battleground.
- Winter: As a sign of increasing tension between the two countries, Canada proves reluctant to allow American troops on Canadian soil or allow American planes to fly over Canadian airspace. American and Canadian tensions rise, but Canada eventually backs down, and U.S. troops pass through Canada. This sets the stage for the Canadian annexation in 2076.
- The first suit of T-45d power armor is deployed in Alaska. While lacking the full mobility of future versions, this power armor is incredibly effective against Chinese tanks and infantry. Its ability to carry heavy ordnance becomes key in various localized conflicts, and it has the power to destroy entire towns without endangering the wearer. China rushes to create its own versions, but they are many years behind the United States.
- By this year, a Nuka-Cola machine can be found on almost every street in America.
- Van Buren (not confirmed as canon) Senator Todd Peterson decides to build a secret bunker to house himself and his family should war break out. Senator Peterson is a wealthy man in his own right, but lacks the funds necessary for such a project. Through secret dealings with Poseidon Oil and a covert branch of the government known as the Enclave, the final funding for the project is attained. A construction site is chosen in southern Colorado and work begins.
- Canada begins to feel the pressure from the United States military as the U.S. draws upon Canadian resources for the war effort. Vast stretches of timberland are destroyed, and other resources in Canada are stretched to the breaking point. Many Americans refer to Canada as Little America, and Canadian protests are unheard.
- February 11: By order of the U.S. government, all Patriot's Cookbook magazines are banned and incinerated. However, many magazines still remained in circulation.

- Van Buren (not confirmed as canon) Completed B.O.M.B. missiles are sent to different space centers around the U.S. so they can be carried into space and installed into the B.O.M.B. satellites. The process is slow, but it is being carried out fairly regularly.
- June 3: Canada is fully annexed by U.S.A.
- Van Buren (not confirmed as canon) August: The Ballistic Orbital Missile Base, or B.O.M.B.-001, is completed and partially functional (for security and maintenance bots) using a temporary onboard generator. The only thing the base needs are the manually input final launch instructions and codes, and the main power reactor.
- September 15: As China becomes increasingly aggressive with their use of biological weapons, the United States government felt that a countermeasure was needed. The Pan-Immunity Virion Project is officially formed and plans are made to begin experiments at the West Tek Research Facility in Southern California.
- Contrary to their claims of seeking only to retake Alaska from the Reds, American power armor units, infantry, and mechanized divisions are deployed to China, but they become bogged down on the mainland, putting a further drain on American resources and supply lines.
- Van Buren (not confirmed as canon) Government decision makers order the dumping of radioactive waste into Eagle Rock's lower mines. Enclave politics help secure a contract for Poseidon Energy to develop and use their AGRICOLA mining robots in the operation of the dumping ground. Not surprisingly, the AGRICOLA lab turns out to be a pretty good bunker as well.
- June: Construction of Vault 112 ends.
- June 24: Negotiations between the U.S. and other world powers come to a dramatic end, with the president walking out of oil talks with the other world powers. After a much heated debate, the president stormed out of the meeting and declared that the last known supply of petroleum will be used exclusively by the U.S. and the U.S. will not sell or trade any oil to outside parties.
- Van Buren (not confirmed as canon) July: The new Bloomfield Space Center completes construction. The facility's first task is to complete the space rockets Hermes XIII and Hermes XIV to fly to B.O.M.B.-001 and -002 – respectively - (originally slated for a Mars mission before new orders arrived).

- May: Vault 112 seals two years early, for Stanislaus Braun's sadistic desires.
- June 30: FEV experiments continue at West Tek with batch 10-011, with white mice as subjects. Increased size, muscle density, and Intelligence are noted.
- November 9: FEV experimentation (batch 10-011) on rabbits is concluded. Increased size, Intelligence, and (this time) aggressiveness is noted. Apparently, it was hard to determine whether the flatworms in the previous experiments were angrier and more violent than normal. Frankly, the researchers cannot be blamed for this.
- REPCONN Aerospace is bought out by RobCo Industries.
- January 3: A military team under the command of Colonel Spindel is sent to the West Tek research facility to monitor the experiments in the interest of national security, due to fears of international espionage.

- January 12: Splicing in several new gene sequences into their test virus, dogs are injected with batch 11-101a at West Tek. Although increased strength was noted, increased intelligence was not. Using batch 11-011, experiments are conducted on raccoons. The same results are noted, but the attempted escape of several infected raccoons causes Major Barnett to terminate the escape... and the test subjects. Two pairs of raccoons, however, are unaccounted for.
- January: The United States annexation of Canada is complete. Canadian protesters and rioters are shot on sight, and the Alaskan Pipeline swarms with American military units. Pictures of atrocities make their way to the United States, causing further unrest and protests.
- April 15: Once all secondary tests and studies are done on the test subjects, all dogs from the batch 11-101a Forced Evolutionary Virus (FEV) tests at West Tek are terminated... from a safe distance.
- June: Power armor prototype completed, resulting in the T-51b power armor. This is the pinnacle of power armor technology before the Great War. Many of these units are sent to China, and they begin to carve a swath through the Chinese forces. The Chinese resources are strained to the breaking point, and the supply lines from the nations China has annexed begin to break down.
- July: Flotation Homes and Seaweed is published by Vault-Tec.
- August: Food and energy riots begin in major cities throughout the United States. Military units begin to be deployed in cities within the United States to contain rioters, and many temporary prisons are constructed. A state of emergency is declared, and martial law soon follows.

Units originally serving in China and the Anchorage Front Line find themselves fighting Americans at home. Food riots increase, and many civilians are killed. Several soldiers defect from the military both in Canada and the United States. They are captured, and are sent to military prisons.
- February: FEV Research is leaked to the world through an unknown source. Protests in many major cities and governments around the world, as well as accusations that the U.S. was responsible for the New Plague. F.E.V. is seen as the threat, and serves only to fuel tensions. The governments of the world fear what the U.S. is up to. Speculating anything from trying to make a breed of super soldier, to trying to make Hitler's master race, they begin to panic.

- Note: While Lynette says that the city was founded 120 years ago, which would place the event around 2120, the Chosen One later says that it's 70 years before the Vault Dweller left Vault 13. This probably means that Fallout 2 was initially meant to take place earlier, and the dialogue file was not corrected.
- LA Vault opens, the Boneyard is founded and attracts survivors.
- Dr. Richard Moreau is exiled from Vault City for murder. The circumstances surrounding the murder are unknown, but he changes his last name to Grey and heads south.
- The Hub is founded by a man named Angus, who sets up camp around a filthy oasis in the desert, and he proceeds to begin trading with other settlements.
- September 20 - November 15: 28 Mexican survivors, 11 male, 8 female and 9 children, arrive in Zion canyon and settle down.
- Harold rises to the level of a caravan boss in the Hub. His caravans suffer occasional attacks in the wastes, but Harold's caravan outfit survives and prospers... until the mutant attacks begin to pick up a few years later.
- February: The inhabitants of Vault 22 leave their vault due to an outbreak of mutated spores infecting most of the dwellers and overrunning the Vault.
- February 11: About 118 survivors of Vault 22 move out of the Mojave wasteland and travel to Zion Canyon. Most are infected with the spores and bring spore carriers and spore plants to the Zion Valley and attack/kill most of the Mexican survivors already in Zion.
- February 14: According to Randall Clark, the Vault 22 survivors eat the Mexican survivors they took captive.
- February 19 - January 13, 2097: Randall Clark begins to ambush the Vault 22 survivors and continues to until the remaining 34 survivors leave Zion.

- January 13: The thirty-four Vault 22 survivors leave Zion Canyon after 10 months of ambushes from Randall Clark.
- A man named Jonathan Faust leads his group of about 200 people from the overcrowded Vault 15 into the wastes of the outside. Eventually they become a raider band known as the Vipers.
- The Vault City Overseer retires and the Council of Citizens is established. The Council appoints the initial First Citizen.
- May 22: Increasing mutant attacks on Harold's caravans frustrate him to the point of financing and leading an expedition to find out where the mutants are coming from. Consulting with a scientist and doctor at the Hub, a man by the name of Grey, the two of them decide to join forces.
- June 23: Richard Grey's expedition (including Harold) finds the Mariposa Military Base and is summarily scattered and defeated by the mutant inhabitants. Grey is knocked into one of the vats of Forced Evolutionary Virus (FEV) by a robotic arm, and Harold is knocked unconscious, only to awaken later out in the wasteland.
- June 27: Harold, already mutating, is found by traders and taken back to the Hub. His former caravan partners and employees, horrified by his condition, abandon him.
- July: Richard Grey, now horribly mutated by the virus, crawls from the vat, covered with FEV and in terrible pain. Barely able to think or perceive his surroundings, he crawls into the vat control room and begins his audio log. He fades in and out of consciousness, sometimes for days or weeks at a time.
- July–November: Richard Grey begins to acclimate to his condition, and begins his first tests of animals by exposing them to FEV. These experiments and his growing awareness lay the foundation for his plans for the Unity and the master race. He takes the name "the Master".
- November: The first human victim wanders into Mariposa, and Grey consumes him.
- December: Grey continues his experiments on wanderers that enter Mariposa with no success. The creations are flawed (due to the radiation counts in their bodies), making them big but incredibly stupid, and Grey consumes them rather than letting them live.
- January: The Master discovers the problem with the influence of radiation on his mutations, and he begins to choose his subjects more carefully. The first classic super mutants are born. He begins his plans to build an army.
- 2103-2130: Throughout this period, the Master begins slowly gathering test subjects, willing or unwilling, from local human stock. The Great Winter of 2130 and the scarcity of human subjects make building his army difficult.
- Angus rules over growing Hub and establishes himself as governor.

- Winter: Angus is murdered. The Hub is thrown into chaos.
- A band of merchants seizes the water tower in the Hub. They demand anyone wanting water must pay a toll. The Great Merchant Wars begin.
- 2126-2128: The Great Merchant Wars are fought, the Water Merchants seal up the town, but are outnumbered.
- A man named Roy Greene makes peace in the Hub and negotiates a settlement. The Hub's Central Council is formed, composed of two representatives from each of the Hub caravan companies. A long period of indecisiveness and meetings maintain the status quo in the Hub.
- 2131-2135: The Master begins ordering his super mutants to gather human stock from caravans. For many years, the caravan disappearances are blamed on monsters in the desert, and even when the abductions begin to occur on Hub caravans, the deathclaws are blamed. The super mutant army grows.
- A faction within the Brotherhood of Steel led by Sergeant Dennis Allen gains strength, and they urge the Elders to let them explore the southeast Glow for artifacts. The Elders refuse, so Allen and his separatist group splits away from the Brotherhood of Steel, taking some technology and weapons with them.
- Led by Sergeant Dennis Allen, a small group of Brotherhood of Steel separatists make their way to the West Tek research facility in search of technological artifacts. They arrive there twenty days later, and are promptly chewed apart by the West Tek's unforgiving automated defense systems. Wounded, Allen begins to suffer radiation poisoning from a leak in his suit. Before he dies, he logs what happened to the expedition into a holodisk.
- Elder Roger Maxson dies of cancer, and his son, already an accomplished soldier, takes up the role of "General" (Elder) within the Brotherhood of Steel. John Maxson becomes a member of the Paladins, showing tremendous promise as a soldier.
- The Jackals lose a major battle against rival raider clan The Khans, survivors are forced further east.
- The Master begins to mass-produce super mutants. Only about one in six or one in five attempts are successful, and of these successes, only half seem to last to go on to be part of his growing army, called the Unity.
- Spring: Vault 15 opens.
- Winter: Raiders begin to organize in the region as food supplies run low. The Khans and the Vipers begin terrorizing local settlements.
- Around the early 2150s the Vipers recover from their defeat by Angus at the Hub, replenish their ranks from captured slaves and caravan drivers, and begin to establish a power base in the badlands to the North of the Hub (and south of the Lost Hills Bunker). Driven by a religious frenzy (and the need to provide for their much larger numbers of soldiers and disciples), they begin raiding more frequently than before, attracting the attention of the Brotherhood of Steel.
- As their influence slowly spreads throughout the wastes, the Master finds humans, doomsday cultists, and rather than dip them in the vats, he demands their obedience as spies - their leader is a man named Morpheus, an ex-member of the gang called the Rippers, and he pledges his followers to the Master. Morpheus and his cultists form the future core of the Children of the Cathedral.
- Vault 17 was raided and its inhabitants taken prisoner by the Master's Army. They were subsequently turned into super mutants, among them Lily Bowen.
- The Gun Runners begin their career as successful weapon manufacturers and merchants.
- The Brotherhood sends out a few squads of scouts to track the Vipers down - it is more of a training exercise conducted by John Maxson's father, as the Brotherhood is convinced that small detachment of troops in power armor would be sufficient to deal with a group of raiders, no matter how large. One Brotherhood squad, lead by Maxson, finds the Vipers. Expecting the raiders to break and run, Maxson doesn't take into account the religious ferocity of the Vipers (or their poisoned weapons), and when a single arrow nicks him with his helmet off, he dies within hours. John Maxson takes up the role of Elder, and Rhombus becomes the new head of the Paladins.
- The Paladins, now led by Rhombus, begin a full scale campaign against the Vipers, tracking them down and wiping out almost all of their members within the span of a month. Some of the Vipers are able to flee north and east into the mountain range.
- Note: According to Chris Avellone's Fallout Bible #6, the Vipers were never heard from again. It was added there possibly because they don't appear in the final game, but it is inconsistent with Fallout, where the Vipers are mentioned by several characters (Ian, Aradesh, Killian) as still being around. The surviving Vipers must have therefore been still active in California until at least 2161. Furthermore, small groups of Vipers can be found in the Mojave Wasteland in 2281.
- After capturing a caravan of vault dwellers, the Master learns the location of the Boneyard Vault, the future site of the Cathedral. He conquers the inhabitants and sets up operations there, and the human cultists begin to use the Vault as their powerbase. Within the Vault, the Master begins to send out patrols to Vault locations in search of these other Vaults. This move is finalized in the subsequent year, 2156.
- The Master sees advantages in establishing a benevolent "religion" (the Children of the Cathedral), and using them as spies in settlements throughout the wastes. Missionaries from the Children of the Cathedral spread slowly across the wasteland, acting as eyes and ears for Morpheus and the Master.
- The Master learns the location of the Bakersfield Vault, Vault 12, and sends a detachment of super mutants there to seize the vault. Many ghouls are snapped like twigs in the attack, and Set finally parleys with the super mutants, telling them that the ghouls are the Vault survivors the super mutants are looking for. The super mutants, angered at failing to find an intact Vault, set up a small garrison at the watershed to watch the inhabitants and ensure Set's...cooperation in the war to come.
