Prologue
2100 - The end of the First Inner Planet War and the establishment of the United Nations as the supreme government of humanity.
2106 - First attempts to colonize Mars.
2112 - Establishment of a mining colony.
2144 - An unknown spacecraft crashes onto the surface of Mars, causing it to terraform. May arise on Mars, and the planet itself becomes habitable by humans and other terrestrial life forms. The settlers find the wreckage and study it, but hide it from their homeworld.
2148 - Mars declares independence and begins the Second Inner Planet War. In response, the United Nations sends out space marines, but when they came to defeat the separatists, they were attacked by space fighters and warships. Despite the total defeat of Earth's forces in capturing Mars, one warship of the Martian Independence Army was captured.
2149 - In fear of a counterattack from Mars, underground shelters are built.
2150 - The first prototype of a space warship is built. After testing, several types are put into mass production.
2151 - First space skirmishes between the Martian Independence Army and the United Nations Space Fleet.
2154 - The Battle of Mars begins. The earthly forces win because they are largely outnumbered. After the victory, the United Nations Space Fleet begins preparations to attack Mars, but the Martians surrender earlier. The occupation and reintegration of Mars with Earth begins.
2155 - Prothean ruins are discovered by the Martians. In the hope of improving their situation, they forward the data directly to the UN. For handing over the ruins, a significant number of the occupation forces on Mars are lifted, and life there slowly begins to return to normal.
2156 - Prothean data is decrypted. Humanity is discovering Element Zero, and one of Pluto's moons, Charon, is proving to be a mass transmitter.
2157 - First expedition is sent through the ground relay. It turns out that it leads to an uninhabited system with a habitable planet. These discoveries lead to a closer unification of Mars and Earth and lead to the reform of the United Nations into an Alliance of Systems.
2158 - There are debates about the direction in which the fleet is to be developed. Ultimately, they decide to build it based on Prothean technology but continue their research on a ship that crashed on Mars. This is because if he had come here via a relay, this one would be active, meaning they would have to invent another way to travel faster than light. There are also problems with the marking of the fleet. The cruisers that took part in the Second Inner Planet War are, according to Prothean designations, frigates, and according to the ship's data, they are cruisers. This means that the Protheans races and the ship that crashed on Mars have different markings. To avoid problems, there are two different ship markings. One after the Protheans and one after the wrecked ship.
2165 - The terraformation system is recreated. Which increases the number of worlds to settle.
2167 - Shock cannons are invented. Plans begin for a fleet of ships with combined Prothean technologies and new weapons.
2168 - First successful FTL tests take place without the need for element zero. As a result of this, and the discoveries of the previous year, the third type of ship designation is created after the combined prothean and alien technologies. The new FTL propulsion is limited to ships of this category only.
2169 - A new fleet of the Alliance fleet is created with the introduction of the 3rd ship category. 300 ships of the 2nd category are divided into 3 fleets, and the ships of the new type are to form another one. Category 1 ships are to be sold as a self-defense force for many systems and the right to build them. They are approximately 50 Congo-class, 250 Murasame-class, and 600 Isokaze-class.
2170 - Status of the systems alliance fleet: 940 1st category (militia ships), 320 2nd category ships, 70 ships of 3rd category. In the same year, Shanxi's defense fleet receives permission to investigate its relay. 8 Shanxi defense fleet vessels and 2 research ships set out to investigate the relay. During the research, the Shanxi defense ships are attacked by unknown forces.
