The After Colony timeline, or AC for short, deals with the events of Mobile Suit Gundam Wing and its follow-up New Mobile Report Gundam Wing: Endless Waltz. This series is set in a universe in which the Gundams are the primary arm of the space colonies' resistance, rather than forming a small part of a larger army. The After Colony timeline ends sometime before the present-day events of Frozen Teardrop, and is continued in the Mars Century, or MC era, during which that novel takes place.



The following timeline of AC history attempts to synthesize the various official and semi-official Gundam Wing histories. It combines previously-published historical info, capsule summaries of the Endless Waltz and Episode Zero-derived flashbacks.[1]

AC 001

Several nations establish permanent space stations in Earth orbit. This is the first year of the After Colony (AC) calendar.

AC 020

The colony A0206 is constructed at Lagrange point 5. This colony will later become the home of the fierce and mighty Long clan when they are exiled from Earth by their fearful government. (Endless Waltz novelization, Episode Zero)

AC 022

Space colony construction begins at Lagrange point 1. Due to unexpectedly severe conditions and strange new diseases, construction is greatly delayed.

AC 050

Nations begin withdrawing from space, until the countries of the Middle East - leaving the oil industry and looking for a new enterprise to invest in - join the colony project. Colony construction begins at the other Lagrange points.

AC 070

Due to scarce resources and limited supplies from Earth, disputes break out at each Lagrange point. The Middle Eastern nations intercede and negotiate an end to the conflicts.

AC 087

The colony V08744 is constructed at Lagrange point 2. (Endless Waltz novelization, Episode Zero)

AC 102

An Island 2 type colony is completed at Lagrange point 1 (L-1). With this success achieved, the colony project goes on to construct population centers composed of multiple colonies, popularly known as "colony clusters."

On Earth, international disputes continue to escalate. Civilians flee the conflict by emigrating to the colonies, and soon 15% of the human population is living in space.

AC 130

With Earth's territorial lines redrawn, the conflicts die down. In spring of that year, twin princesses Katrina and Sabrina Peacecraft of Sanc Kingdom are born. (Frozen Teardrop)

AC 133

In the process of negotiating a lasting peace between the warring nations, the "United Earth Sphere Alliance" is established. In order to keep the peace - and deal with nations that oppose the new world government - the Alliance Forces are formed. One of the Alliance's key financial supporters is the military-industrial combine called the Romefeller Foundation.

AC 139

The colony autonomous government is established.

AC 140

One by one, Earth's nations join the Alliance. As their mother countries join, the colonies are also enrolled, willing or not. The colonies are critical of the Alliance and its intentions, and the Alliance decides to respond with force in order to silence its critics.

AC 145

The 19 year old Heero Yuy becomes the personal tutor of 15 year old Katrina Peacecraft. [Frozen Teardrop]

AC 147

In the name of peace and justice, the Alliance invokes the authority of its member nations to forcibly seize control of the colonies.

AC 149

The Alliance assembly transfers control of the previously-independent colonies to the mother countries that originally constructed and settled them. These nations then kindle a new colony emigration boom.

AC 150

The colonists, favoring autonomy, become increasingly dissatisfied with Alliance control.

AC 165

In order to peacefully oppose the Alliance, the citizens of the colonies elect Heero Yuy as their representative. His charismatic leadership strengthens solidarity between the colonies.

Brigadier General Septem, the ranking Alliance officer at the colony, permits Specials officer Treize Khushrenada and three of his cadets, including 12-year-old Lucrezia Noin, to join the battle.

Alliance officer Sally Po reports that the mission was successful, ensuring that A-0206 will be left alone in future. (Endless Waltz novelization, Episode Zero)

AC 195

At each colony cluster, anti-Alliance rebels prepare for Operation Meteor. Planned by Dekim Barton and coordinated by Quinze, the plan involves dropping a space colony on Earth to create a climatic catastrophe and global chaos. Then five super-advanced mobile suits, the Gundams, will be sent to Earth to seize control of the planet. The space colonists will thus become the rulers of the human race.

At the L3 colony cluster, designated Gundam Heavy Arms pilot Trowa Barton realizes that Doktor S and his aides are trying to subvert his father's plan.

"Operation Meteor" begins - apparently ahead of schedule. Five Gundams descend to Earth and begin attacking Alliance military bases and factories. Their goal is to cripple the secret society OZ.

AC 195, May 19

The Gundams attack an Alliance meeting at the New Edwards base. The Alliance's military leaders, who had that very day decided to begin disarmament and make peace with the colonies, are killed. OZ then discards its Specials cover and launches "Operation Daybreak", overwhelming the Alliance's terrestrial forces and seizing control of Earth.

White Fang (a movement fighting for the independence of the space colonies, led by Quinze and the erstwhile Zechs Merquise) and the World Nation (the Romefeller Foundation's world government, now led by Treize Khushrenada) begin a massive space battle. Treize is killed in battle, and the World Nation surrenders. White Fang's last gambit, an attempt to drop the space fortress Libra on Earth, is foiled and Zechs disappears.

AC 196, April

Heero Yuy, piloting the Wing Gundam Zero, destroys an orbital beam cannon before it could attack Earth. Relena Darlian secretly visits the supposedly deceased Doctor J.  (Gundam Evolve, Frozen Teardrop)

AC 196, December 24

Dekim Barton returns in order to carry out the original Operation Meteor. As the L3 colony X-18999 neared completion, Dekim revealed to the people of Earth the leader he had set up for the coming ages: Mariemaia Khushrenada, the daughter of Treize Khushrenada. During this time, Mariemaia made a speech to the Earth Sphere declaring the independence of X-18999 while simultaneously declaring war on the Earth Sphere Unified Nation. From the resource satellite MO-III, Dekim told the newly resurfaced Zechs Merquise of his intentions of dropping X-18999 onto Earth. Ironically, the colony drop was foiled by three Gundam pilots, who were originally meant to restore order to the chaos created by the destruction of X-18999 in the original operation plan.

Zechs destroys MO-III, but not before Dekim Barton escapes in a shuttle. Mariemaia's forces occupy Brussels, the ESUN capital, establishing Barton family control. However, Zechs, Noin, and the Gundam pilots engage Mariemaia's forces guarding the presidential residence. They disable most of the Mobile Suits without harming their pilots before being outnumbered and cornered. However, Wing Zero appears and fires its twin buster rifles at the presidential shelter, breaking through all of its defensive layers. Dekim, believing that he is still not defeated, calls to Mariemaia to rise up as ruler of the Earth Sphere; Mariemaia complies, only to be slapped by Relena, bringing her to her senses. Dekim refuses to let her brainwash his granddaughter and shoots Relena. However, Mariemaia takes the shot for her and falls to the floor. Dekim was unconcerned, as he could always make another puppet. But before he could take another shot, he was killed by a soldier loyal to Treize, who apologized to Treize for betraying his ideals, ending the Mariemaia Rebellion.

Note & Trivia

  • In Gundam EX A, the After Colony era is considered to be the most significant "world" to the people of Jupiter X. Much like the world of EX A, there is no people who represent evolution of humanity (Newtype, SEED factor, etc.), yet the denizens of After Colony show no sign of regression like EX A's do.
