Timeline:

1974 AD: The Cold War comes to an end with a military coup in the Union of Soviet Socialist Republics in favor of a Confederacy of Independent democratic Republics, backed by the people of all the occupied countries. The United States enters a formal alliance with the new Democratic Soviet Russian Federation the next year.

1986 AD: The Space Shuttle Challenger launch is aborted when someone spots an anomaly on one of the booster rockets, leading to a discovery of the O-Ring flaw. The shuttle program is suspended for six months as the flaw is fixed. The Warsaw Pact is dismantled via treaty, Germany finally reunited. The DSRF and United States fund much of the reconstruction for the WarPac countries.

1987 AD: Dr. Minovsky discovers the Minovsky Particle thanks to H-3 taken from Luna. The first 'beam weapons' are tested by the Russo-American Testing Compact, known simply as Overwatch. The same year, a new titanium alloy is revealed. Called Lunar Titanium, as it was made on the DSRF/US space station in orbit of Luna, Earth's moon, it is lighter and stronger then regular titanium.

1989: Overwatch produces a new 'walking tank' prototype. Six meters tall, with wheel assemblies on its legs to get around quickly, the machine can only get airborne by jumping, and even then not very high. It is powered by experimental Minovsky fusion reactors, however, resulting in greatly increased power output over conventional fuels.

1991: Overwatch produces a new computer system based on quantum particle analysis. It is insanely bulky and useless, but it is a view of the future. The People's Republic of China declares war on the CIR. The Russian Federation and United States condemn the event before they are forced into the conflict.

1994: The Chinese War comes to an end, the Chinese losing to NATO and Russia's new 'mechs'. The technology will stagnate for another 40 years.

1997: The governments of the world begin a space colony development plan, to create more room for Earth's growing population. Bernal sphere-types are built piece by piece in Earth orbit.

1999: the first O'Neill-Class Island-3 is built, named Londonian after ancient Roman London. It is chosen as seat of government for the L1 colonies. George Glenn is born and given genetic enhancements after birth via retroviruses.

2001: September 11 attacks. The world rallies to crush radicalist terrorists in a War on Terror.

2003: The US, Russia, and Britain attack Iraq for harboring Terrorist Cells connected to the events of 9/11. With a few adjustments to operate in the desert sands, American and Russian 'mechs' are more than a match for the best weapons that Iraq can field. The L1 colony group grows to five I3 O'Neills.

2008: Overwatch acquires DARPA and Lockheed Martin's Skunk works, as well as other experimental agencies. The United States suffers a civil war that leaves the country in chaos, forcing their northern neighbor to take up the reigns, forming the United North American States, with the capital in Ottawa.

2010: The L1 Colony Group is now at 12 I3 O'Neills, and a second Colony group begins construction at L2.

2017: George Glenn enters university. An M1A4 Abrams MBT tests the first Minovsky beam cannon.

2020: UNAS constructs the first space warship: the Drake-Class frigate. The ship will remain in service until the Reaper War. The L2 colony group declares independence as the Republic of Zeon under Zeon zum Deikun, a former German People's Army officer.

2021: George Glenn graduates university, is immediately accepted into Overwatch. The United European Compact launches their first space warship, the Salamis-Class light cruiser. The DSRF absorbs the heavily indebted and demoralized PRoC, becoming the Chinese-Russian Federation. Former WarPac countries cede their borders to to NATO.

2025: Zeon zum Daikun declares his Newtype ideology, stating humanity must evolve and adapt to properly survive and thrive in space.

2026: The UNAS and CRF join hands in an alliance that, in 10 years time, will give birth to the Earth Federation. The African Union puts forth efforts to unite the continent, led by Egypt. An UNAS/CRF/AU mission sends a craft to Mars.

2028: George Glenn prepares to depart for Jupiter on an H-3 Mining and Exploration mission. As he departs, he announces his status as genetically engineered, and posts data on the internet to allow the creation of more like him, 'Coordinators' to assist and lead humanity into the next step of evolution, in line with Zeon Daikun's Newtype Ideology. The Republic of Zeon declares itself a genetic engineering state, mostly for the purposes of warfare. However the rest of the world remaining largely skeptical - if not outright hostile - towards Coordinators.

2036: The Earth Federation is formed. Coordinators form up 5% of the human population of 15 billion, 80% of that number being Zeonic. The countries of Papua New Guinea, Malaysia and the Solomon islands join with Japan to form the United Emirates of Orb.

2038: Zeon zum Daikun is assassinated, his associate Degwin sodo Zabi taking control of Zeon as it turns into the Principality of Zeon.

2042: George Glenn returns from Jupiter, his ship carrying plenty of H-3, as well as a giant space-whale fossil discovered at Jupiter - proving the first example of Extraterrestrial life beyond Earth. A new set of colonies, called PLANTs, begin construction at L5 - Rather than I3 O'Neill Cylinders, the PLANT colonies take the shape of giant hourglasses.

2043: The EFF creates the Nelson-Class heavy cruiser and Magellan-Class battleship. The PLANTs turn their cargo ships into armed frigate and cruiser-class ships, named Laurasia and Nazca-Class. The AU-area of the Federation is anti-coordinator, resulting in the buildup.

2045: The XMS-01 is built. 02 through 04 prove to be failures, the XMS-05 Zaku I being the first modern Mobile Suit. Blue Cosmos is formed as an environmentalist group, but they turn anti-coordinator within the first six months. The Mars colony discovers alien ruins on the planet's surface.

2049: The MS-06 Zaku II is produced. Groups in the PLANTs secretly begin their own Mobile Suit Development. The ZGMF-X1017 GiNN is the result of this work. Zeonic and the PLANT design bureau begin long collaborations. The Federation's Mobius Mobile Armors enter service as a stopgap for the GAT-X and RX design programs to run their courses.

2050: The Republic of Zeon is reorganized into the Principality of Zeon is declared. The PLANTs form the Zodiac Alliance of Freedom Treaty. The Federal outpost on Mars discovers an archive at the south pole.

2053: The Earth Federation Space Forces 4th Fleet launches a surprise attack on the PLANTs, secret Blue Cosmos elements striking the agricultural colony of Junius Seven with a nuclear missile. As a result, Zeon and ZAFT declare war on the Earth Federation. Two days after declaration, it was discovered that the strike was not authorized by the Federation Council, but rogue ZAFT elements join with Zeon forces to attack Londonien. The GAT-X units are stolen, their more advanced weapons being used by ZAFT's elite Sabers Squadron. The RX series is more lucky, the Pegasus-Class assault carrier White Base taking the RX-75 Guntank, 77 Guncannon and the RX-78 Gundam from the colony it was based at. Blue Cosmos attempts a coup and fails. The PLANTs withdraw from the war less than three months in. Zeon pushes until the end, nearly dropping three colonies on Earth before ZAFT turns on Zeon, joining EFF forces in cutting their throats. The Zabi family is assassinated by Char Aznable, sans Mineva, who is a child, escaping to Axis.

2055: ZAFT creates its 'Second Stage' and 'New Millennium' Mobile Suits: the ZGMF-1000 'Zaku Warrior', ZGMF-1001 'Zaku Phantom' and ZGMF-XX09T DOM Trooper lines inspired by the MS-06 Zaku II, and MS-09 DOM of Zeon, as well as development of the ZGMF-2000 GOUF Ignited inspired similarly by the Zeon Ground-use MS of the same name. Five machines based on the GAT-X line are also developed, as well as the ZGMF-X10A Freedom and ZGMF-X09A Justice that were produced near the end of the last war. The five new 'Specialty' machines have a unique Deuterion Beam System, allowing a warship to recharge their systems in the event that their Minovsky Reactors are non-functional, forcing them to rely on batteries. The Earth Federation begins developing the RX-78GP line.

2058: The GP02 is stolen by the Delaz Fleet. The Albion is sent to recover the machine. ZAFT and the Republic of Zeon engage in a cold war that eventually results in drawing the Federation into the affair, calling it the Second Valentine War.

2060: Gilbert Durandal is killed by the crew of the EAS Archangel, ending the SVW. The Archangel is decommissioned soon after. The PLANTs surrender authority to the Earth Federation. The XA and XS series Mobile Suits are given to the EAS Dominion.

2070: The Republic of Zeon folds into EF control. Humanity is finally united. The archives on Mars are disclosed, resulting in a ship being sent to Pluto. Pluto's moon, Charon, is revealed to be an exceedingly ancient device known as a Mass Relay, allowing for near instantaneous travel from one star system to another.

2071: Mobile Suit Development continues, given that the Protheans, creators of the Mars Archives, mention in said archives a race of machines that wipe them out, called the Reapers, and the EF has to be ready for these 'Reapers' to eventually make a return. Mobile Suits are considered to be the EF's ace in the hole, since the Protheans never developed anything similar from what they can tell in the Archives.

2076: A development team in the PLANTs makes an improvement in the Deuterion Beam System, allowing the emitters to be mounted on unmanned satellites, and the beam to be used to charge up high-power beam cannons, leading it to be renamed the Satellite System. Neo-Zeon seizes five colonies and attempts to drop them on Earth as an act of revenge. The EFSF, now massively enlarged, fights back. Three colonies hit Earth, but unlike AW, they are deep-water impacts, causing little more than coastal damage. Char Aznable, legendary Zeon ace and now leader of the Earth Federation Senate, denounces the actions of those that claim to follow his father's teachings.

2080: the EFSF's AEUG movement gains ground, moving the capital of the Federation from Earth to Londenian. The New Class Program produces ZAFT, Zeonic and EF ships such as the Reloowla, Ra Cailum and Minerva-Classes, as well as the Archangel-Class, named after the EAS Archangel.

2082: The Earth Federation begins colonizing other worlds through the Mass Relay System, establishing colonies at Arcturus and Eden Prime. I3 colonies are built in orbit of both worlds.

2085: Shanxi settled. The Federation undergoes a massive review to purge corruption and end corporate influence. EFSF designs its' first ME-based warship, the Geneva-Class cruiser. Older model ships refit with ME technology.

2098: Systems Alliance founded to maintain human unity. Ultimately answering to the Federation, the Alliance is the ultimate neutral authority between the colonies and Earth.

2148: The RGM-89 Jegan, GAT-04 Windam, and AMS-119 Geara Zulu become standard issue Earth Federation/Systems Alliance, Reserve, and Colonial Militia Mobile Suits. Older models are refit with ME technology as needed.

2154: Current year...
