The Galactic Colonization (GC for short) Era was the fictional timeline used by the anime television series Mobile Suit Gundam Galactic and its subsequent spin off projects. This timeline was noted for its inherent similarities to Gundam SEED and Gundam 00.

Along with Mobile Suit Gundam and Gundam SEED, the Galactic Colonization Era Universe was one of several series to include multiple TV series (Two so far), an OVA series special, a theatrical movie and several specials. In terms of development, Galactic was seen as one of the most developed series seen, with Mobile Suit Gundam taking first place.

Galactic Colonization takes place several hundred years after the Anno Domini timeline and one hundred years into the GC Era. Gundam Galactic was noted to be one of the few series to be split into two separate chapters, along with several specials and expansions.



Humanity had expanded beyond the Sol System and into all corners of the Milky Way Galaxy. Under one government, the Unified Earth Government, peace was ensured for centuries, culminating in what some historians referred to as the New Age of Humanity. Unfortunately, the everlasting peace many had taken for granted would seemingly crumble right before their eyes. A faction led by a man named Jean Regendorf revealed the true tyranny of the UEG, and their extensive use of propaganda and indoctrination to pacify and control the masses. However, Jean's revelation primarily fell on deaf ears and Jean's rebellion was quickly quashed, but not before he and his followers fled to the less-controlled Outer Colonial Territories. Decades later, Jean would resurface and pronounce the succession of the Outer Colonial Territories as the newly created Human Federation. Unwilling to acknowledge the HF, the UEG declared war on them, enveloping the entirety of the Milky Way Galaxy in conflict.


Primary Timeline

Prior to GC
Early 2000s

2020 - As the Earth's Population brims to capacity and resources become thin, all of Earth's Nations attempt to unify with each other in an effort to mitigate and solve the impending crisis.

  • December 16, 2020 - Due to contrasting ideologies between the countries, the unification fails and the theorized Resource Conflict breaks out.

2021-2033 - A mysterious man known as Andrew LeBlanc appears and apparently unites all of the Eastern Hemisphere under his leadership. Rather than continue down a path of war and destruction, Andrew extends an ultanium to the Western Hemisphere: agree to a ceasefire and unite, or face complete destruction. Well aware of Andrew's achievements, the Western Hemisphere unconditionally surrenders.

2034 - The already defragmented United Nations is rendered obsolete, falls, and is reborn as the newly established Unified Earth Government, with Andrew LeBlanc as Leader. EarthGov, as the UEG was eventually called, formally announces the Human Colonization Project. A plan of Reconstruction is eventually implemented following the declaration of the ceasefire. Now with peace, all of Humanity is able to focus their energies onto Human development and progression.

2066 - As part of the Project, the Moon and Mars are subsequently colonized and made inhabitable for Humans, with both having gone through an extensive terraforming process.

2075 - Construction of the first self-sufficient Colonies begins on Lagrange Points 1-5. Each of the Lagrange Points are later named after Ancient Figures: Aristotle (L1), Plato (L2), Socrates (L3), Euclide (L4), and Ptolemy (L5).

2076 - Construction of Titan Station begins near its namesake, Titan - Saturn's largest moon.

2088 - Titan Station is completed and is considered to be the Unified Earth Government's first major Outpost.

2089 - With input from an aged Andrew, the Unified Earth Government managed to develop the first experimental FTL engine, the Warp Gate Drive. Spurred by prospect of expansion, the Unified Earth Government begins construction of the first Exploratory Vessels.

2114 - Construction of the Exploratory Vessels are complete. The first Vessel to be completed is christened UEG LeBlanc.
