Timeline of the Alliance Republic:

2025: The question of are the Humans alone in the Galaxy in answered at last. The answer of no as humanity discovered a new species. But it was the Aliens who arrived on Earth and contacted Humanity. When they first arrived, there was worldwide panic that the Earth was about to be attacked by a much advanced species but quickly, the threat ended when the Aliens made peaceful contact with the Humans. These Aliens looked almost human only having blue skin and red eyes. They called themselves the Chiss and had arrived after discovering an old probe sent by humans during the Space Race. The Chiss were peaceful but saw that Humanity was heading into extinction due to overpopulation on one planet and so the Chiss decided to help the Humans advance their technology in order to expand into space to save their people from extinction.

2035: After 10 year, the Space Age is back and the humans finally manage to send the first man to Mars thanks to Chiss technology. Resources are sent towards Mars and the Humans and Chiss work together to help make Mars more liveable.

2040: Thanks to the Chiss, Mars' atmosphere develops to protect people from UV radiation from the sun and also allows humans to breath on Mars without space suits. Earth begins to send the first colonists to Mars.

2050: Mars begins to flourish thanks to the many colonists that arrive. Farming is made easy since Water begins to flow on Mars making the planet more like Earth. While the Planet still has its red colour, rivers flow all over Mars making the Colony an opportunity for people to live on.

2070: Humanity's population continues to get bigger and even Mars hasn't enough resources to sustain the population so humanity begins looking even further into the Solar System. Venus and Mercury are unfit for habitation as Venus' clouds are too much even for Chiss Technology and Mars is too close for the sun. But Energy stations are constructed in Mercury's orbit to generate Solar Power. Earth's Moon has a small colony develop but not as large as Mars and is more of a military outpost and Cargo port since there were no resources on the Moon. The other planets have more luck. The moons of Mars Phobos and Deimos are mineral rich and small mining colonies are established. On Saturn, the largest moon Titan is made habitable by Chiss technology and colonists start settling on the Moon and fuel production for ships becomes the main trade of Titan thanks to the Methane Lakes. The other moons of Saturn are used to help provide resources to Titan's colony.

2080: The moons of Jupiter start to be colonised with Callisto and Ganymede becoming Colonies while Europa becomes a major water production for fresh water to the colonies. Io has a scientific research base established to study the many volcanoes on the moon.

2100: Humanity had now expanded towards the edges of the Solar System with the settlers heading towards Uranus and Neptune. On Uranus, the moons of Ariel, Oberon and Titania become settlements while Neptune only has Triton as a settlement. The only planets in the Solar System not be touched are Pluto and Eris. In the Asteroid Belt between Mars and Jupiter, companies begin mining Asteroids while the dwarf planet Ceres become a major trading outpost for these companies.

2120: Despite having nearly 100 years of peaceful colonisation, soon settlers start to begin wanting to be their own government instead of being controlled by Earth. On Mars this leads to a far right group known as the Settlement Defence Front leading a military coup against the Governor of Mars and take military control of the planet. Earth begins to send warships and troops to retake control of the colony.

2122: After 2 years of fighting, the Charon Accords are signed and Mars becomes an independent power.

2130: Despite the hopes of the Charon Accords bringing peace, SDF becomes more ambitious and builds up its own army and fleet which panics Earth leaders who begin to establish a more firm control over their colonies. The Leaders of Earth unite to form one government and take better control of their colonies. But they are forced to give control of Uranus to the SDF to avoid war.

2132: Earth's public calls for war when word reaches them of SDF murdering colonists on Uranus and tensions rise when SDF take military control of Titan.

2134: Despite people wanting war, Earth decides not to risk all out war which could devastate humanity. However War starts when SDF launches a surprise attack on Earth which cripples Earth's fleet and takes control of the Moon. Several Ships survive the attack and fight back against SDF across the Solar System.

2135: The War ends with Earth's victory and the death of most of SDF leadership. The war leaves massive losses on humanity but the Chiss help them recover. The war makes it clear that humanity must be united now and so the government is reformed so all colonies elect someone to represent them. The Chiss now begin to help humanity develop hyperdrives which can take them towards other systems for habitation.

2137: War veteran Nora Salter leads the first group of colonists towards the world outside the Solar System. They arrive at the Arcturus system and begin exploring the new system. They discover the Gas Giants are good sources for fuel towards the Hyperdrives. The colonists eventually settle on the Planet Benning which is a located Euler system not far from Arctutus.

2140: The Age of Exploration begins with funding from wealthy people from Earth to start exploring the Stars. Warnings from the Chiss make sure that the exploration vessels are defended by an escort but not too large so they don't provoke a war with any species that they discover. An important part of these talks were Protocol Droids that the Chiss had helped develop which could help translate different species' languages.

2150: A human exploration fleet makes first contact with a new species. On the planet known as Ryloth, they come into contact with a species known as the Twi'leks. These aliens were similar to the humans but had a range of different skin tones and prehensile appendages that sprout from the back of their head and went down their back. The Chiss and humans establish contact and begin to help them achieve space travel. Humans decided to help any pre-spaceflight species they could find in order to build up alliances.

2160: Another new species is discovered on the planet Shili known as the Togrutas who look just like the Twi'leks only they had multiple colours on one body rather than just one. These species were more advanced so helping them achieve spaceflight was quick.

2170: On the planet Miral, the near human species known as the Mirialans. These people are seen as near human since they look like humans and so they quickly achieve spaceflight.

2171: More colonists begin leaving the Solar System to settle on newly discovered Garden Worlds so the use of machines to make planets liveable is not used as much but the technology is kept safe in case it is needed. On Mars, a survey team in the South Pole discovers a small data cache which is discovered to have been from an Ancient Space faring species known as the Protheans which disappeared 50,000 years ago. They have some technology but it is considered inferior to what has already been created. But they soon discover something known as the Mass Relays which allowed the Protheans to travel across the Galaxy.

2172: One of these Mass Relays is discovered to be encased in ice at Pluto's moon Charon. This worries humanity as there is a gateway into their system. Governments vote to destroy it but the Chiss fear that because it contains so much energy, it could create a supernova. The Chiss are eventually able to harvest the energy contain in the Mass Relay on a fuel ship. The Relay is then destroyed and humanity decided to destroy any other relay then find in their territory.

2175: A group of scientists research the energy that was harvested from the relay but an accident during an experiment exposes many people in Singapore to dust form element known as Element Zero which is used as fuel for spaceships. The fuel doesn't work for large warships but was good enough to be used for fighters.

2180: With Humanities power expanding and new Colonies being formed, Humanity decided to construct a large space station in the Arcturus System to act as their alliance parliament. Each major colony would have a representative along with colonies founded by other aliens that were part of the Alliance such as the Twi'leks and Togrutas. Another new species discovered were the Rodians of the planet Rodia, a reptilian race with green skin or sometimes yellow. Their home planet was a swamp but they lived in domed cities, they jumped at the chance to find new homes and quickly became members of the Alliance so that they could find better places to live.

2200: A joint exploration mission discovers another species on the jungle planet Kashyyyk known as the Wookies. These aliens are full of hair and are expert warriors. However they were unable to speak any other language other than their own so Protocol Droids became important. The Wookies join the Alliance and become respected warriors among the Alliance races. Also, a second accident with Element Zero occurs during the harvesting of a Mass Relay exposing more people to Element Zero.

2201: Arcturus Station is complete and become the headquarters of the Alliance. Every home planet of the species along with major colonies has a seat in the Parliament. These Colonies included Benning, Eden Prime, Elysium, Horizon, Luna, Mars and Terra Nova along with the planet Kiros which was founded by the Togrutas. Many of the Colonies had mixed populations with a mixture of different species but there were many more colonies through the area that the Alliance controlled which were still quite small. Many of these smaller colonies were either just small mining colonies on Asteroids or gas mining on large Gas Giants which were too small to be important except for the raw material they extract. Others were farming colonies which had not grown yet like Eden Prime had done which was a large farming colony. Also, many children who had been exposed to element zero begin to develop telekinetic abilities but the Alliance has no idea how to help these people.

2201: The Alliance is official now known the Republic of Allied Species to show unity and every race is treated the same. This new galactic government quickly makes contact with another species known as the Besalisks on the planet known as Ojom. In the same year, explores discover a creature known as Yoda on the planet Dagobah. This small green skinned creature finally helps the Republic understand the telekinetic powers that people have been developing which is known as the Force. An order is founded on Arcturus Station known as the Jedi Order which helps children who develop these powers train.

2200-300: The next hundred or so years results in the age of discovery as funding from Republic investors results in the discovery of a number of new species. These include Zabrak from the planet Iridonia, the Iktotchi from the moon Ikotch the Kel Dor from the planet Dorin and the Sullustans from the planet Sullust. This age also allows the Republic to control a large amount of territory and colonise many worlds for different purposes weather for farming or for mining and although some groups start small independent colonies, most are eventually absorbed into the Republic weather peaceful or by force.

2251-65: The Republic Wars against Slavery begin after The Republic comes into contact with the Zygerrian Slave Empire. After first contact in 2245 with both groups, slavers soon begin to raid the outer parts of the Republic which include colonies and even Ryloth. Eventually the Senate vote for war and soon sends their fleets against the Slave ships which soon result in full scale war between the Republic and the Zygerrian Empire. The War ends in 2265 with the Invasion of Zygerian in Republic victory. The Republic forces a harsh treaty on Zygerria which forces them to abandon Slavery and much of their territory becomes Republic Territory with new colonies and free people who accept the Republic.

2270: The Zygerrian revolt forces the Republic to withdraw from Zygerria and the Zygerrian People accept Slavery again but their power never reaches as far as their home system. The Senate vote that Zygerria is not worth their trouble if they leave the Republic alone and so the Republic withdraws from the region but steps up defence of the outer areas of the Republic. The Republic also forms an Alliance with the Bothan Species who help spies on the remaining Slavers and become agents of the Republic although they are not classed as a Republic Species since their Homeworld is not in Republic controlled territory.

2310: The Republic of Allied Species now controls a large amount of space and they end up coming into contact with a group known as the Trade Federation. This Trade Federation includes a group of Species who have hit a hard time due to them being exiled from a group known as the Citadel. The Trade Federation members arrive on Arcturus Station and warn the Senate of the Citadel and how the Trade Federation was exiled from their space after they refuse to shut down their battledroids which the Citadel considered AI. As a result, the Trade Federation which were led by the Neimoidian species were forced to start funding criminal activity to prevent collapse. After the Senate makes an offer, the Trade Federation joins Republic Space and become major investors.

2320: A Trade Federation exploration fleet discovers the planet of Mon Cala and the two major species on the planet, the Mon Calamari and the Quarren. The two species are currently at war but the Republic managed to help them negotiate a ceasefire and both species join the Republic by 2325.

2332: Despite having years of peace, the first major internal struggle begins when the Mandalorian Wars begin. The Republic colony of Mandalore is home to a warrior people who love to fight and clans would often fight each other which over time has devastated the once proud garden world. The wars begin when a extreme group of Mandalorian warriors known as Death Watch decided to declare independence and follow their own code and attacked nearby colonies. This resulted in the Republic being forced to declare war against one of their own colonies.

2335: Other colonies in the Mandalore system such as Kalevala and Concordia join the revolt and the revolt is hard for the Republic to fight as the Mandalorians are expert warriors and fight not for resources but for the thrill of the fight. Fighting becomes extreme and there is talk in the Senate about letting Mandalore leave the Republic but that idea is shot down as the Mandalorians would carry on raiding the Republic and the Chancellor is forced to resign.

2338: The Republic begins to gain the upper hand and capture Kalevala and the one of the Mandalorian leaders, Tal Merrik is killed. Mandalore also descends into civil war between the extreme fighters and loyalist to the Republic led by Clan Wren.

2340: The Republic captire Concordia and begin to land forces on Mandalore and capture Sundari, Mandalore's capital.

2343: The war carries on for three more years and the conspirator Almec is captured and sentenced to life imprisonment. Death Watch and their leader, Pre Vizsla along with Clan Saxon refuses to surrender and they manage to flee Mandalore to the Terminus Systems where they become a mercenary company that is known to be more like raiders. The war is over but Mandalore remains under military control.

2350: While helping to dismantle a Mass Relay near the planet Shannxi, a Republic Exploration fleet is suddenly attacked and forced to retreat. Soon an entire fleet attacks the colony and while the small defensive fleet puts up a massive fight, they are soon forced to retreat and the occupation of Shanxi begins. Right after the retreat, the Trade Federation recognised the attacking ship's design and warns that it is the Citadel species known as the Turians. Unwilling to allow this Citadel to take one of their colonies, the Senate dispatches a massive fleet to relieve Shanxi.

2351: On the Planet Shanxi, the republic citizens start a Guerrilla war against the occupying race known as the Turians which make life difficult and the Turians never have full control as their weapons are unable to deal with the Republic's shields on their tanks due to different technology. Also the Republic Second Fleet quickly arrive and defeat the occupying spaceships which leaves the army with now air cover and the army is eventually forced to surrender.

2352: Following the recapture of Shanxi, the Republic and the Turians make preparations for war after a Turian reinforcement fleet is also defeated. This catches the attention of the Citadel which eventually forces both species to agree to a ceasefire.

2353: Representatives of both the Citadel Council and Alliance meet up to have talks with each other for the first time. While the Republic already knew of the Citadel, the Citadel did not know of the Republic. While the Citadel attempts to convince the Senate to join the Republic, the Senate refuses as they heard about the Citadel being bigots and pushing the lower species around. While both galactic governments agree to trade technology since the Citadel cannot travel without the Mass Relays, it still starts an era known as the Cold War between the Citadel and the Republic.

2355: Because of the Cold War, the Republic allows Mandalore to have control over their planet again and the colonies regain their seat in the Senate led by Satine Kryze, a pacifist who tries to help Mandalore move on from their warlike past but Mandalorian warriors are still prized in the Republic military.

2360: Despite the Cold War, many people from both Citadel and Republic Species settle on each other's colonies which must obey the rules of the area where the colony is. This causes some issues as some Citadel Species such as the Volus find the Republic more appealing than the Citadel as the Volus have been a Citadel Species for hundreds of years and still have not got a seat on the council. This causes a fear in the Citadel that the Volus may choose to leave the Citadel entirely and join the Republic. There are other problems as the Republic refuse to cut down the size of their fleet which they say is important for defence. This starts an arms race which results in more Dreadnoughts being built by the Asari and Turians.

2365: A Republic exploration ship suffers a malfunction and is forced to crash land on a moon in unexplored space known as Pandora. The crew which includes a group of students discover a new species known as the Na'vi which are very primitive and are unwilling to leave their heritage behind. As a result the Republic decides to leave Pandora alone even though the planet is rich in minerals. Although a science base is constructed to study the wildlife and nature of the moon which is kept small.

2369: The Cold War starts to cause problems for a Citadel Species known as the Batarians since the Batarians claim an area of space known as the Skyllian Verge is theirs which causes tensions since the Republic has several major colonies in the Verge and the Citadel is doing nothing to stop the Republic from expanding

2370: The first major crisis in Galactic peace happens. Batarian Slavers attack the Republic colony of Mindoir resulting in many colonists being captured or killed. The Republic demands the return of their colonists and while the Batarians deny involvement, Republic intelligence discovers messages between the Slavers and the Batarian leadership proving their involvement. The crisis sparks into clashes between the Batarian and Republic navies and nearly sparks into all out war. The Council eventually forces the Batarians to release the colonists but the treatment of these captured colonists angers the Republic and many of them don't see the Citadel as doing anything about the Batarians leading to strong anti-Citadel feelings in the Republic.

2371: In protest of the Citadel refusing to stop Republic Expansion, the Batarians close their embassy and become a rogue state. With the Batarians funding pirate raids onto Republic territory, more funding is directed towards defence and the defence fleet of many colonies are expanded to help deal with these pirate raids.

2373: Batarian funded pirates attack the colony of Elysium starting the Skyllian Blitz but the attack is repelled and several Batarian officers are captured in the Battle. This time, the crisis begins the Verge War between the Batarians and Republic with attacks on colonies on both sides. On the joined human and Batarian colony of Anhur, rebels fight against the government which is pro slavery and the rebellion spreads throughout the Amun System. The Citadel declares neutrality in the war but uses spies to see how the Republic fights their wars

2374: A surprise attack by the Batarians destroys the pride of the Republic fleet, the Dreadnought RSV Nick Reyes named after a war hero from the Settlement Defence Front War. The Nick Reyes puts up a big fight against a Batarian Dreadnought known as the Bria named after the moon where the Prothean ruins were discovered for the Batarians and manages to destroy several Batarian cruisers during the fight. But eventually, the Nick Reyes is destroyed with few surviving since the Batarians destroyed the escape pods as well. But instead of demoralizing the Republic like the Batarians hoped, the Republic sends out the powerful Seventh Fleet led by Chiss Admiral Thrawn to avenge the loss and the Bria is ambushed at a Batarian outpost and Thrawn destroys most of the fleet and destroys Batarian power in the area which cripples their ability to lead attacks on the Republic.

2375: Despite the victory of avenging the RSV Nick Reyes, the war is still not going too well for the Republic as several Batarian raids on outer colonies have been successful and the Republic has been unable to destroy the Pirate bases. So in order to show that the Republic is not going to be pushed around, the Republic military orders a small bombing run against the Batarian homeworld as a show of strength. Known as the Dutch Raid after the bomber commander leader Jon 'Dutch' Vander, a squadron of newly developed bombers secretly manage to sneak through Hyperspace and bomb the Batarian homeworld of Khar'shan. While the damage done is minor and gains criticism from the Citadel, the Raid is a propaganda victory against the Batarians and provokes fear in the Batarians.

Later in the same year in hopes of destroying the Republic navy in retaliation, the Batarians attack the Republic planet of Corellia, home of the major Republic shipyards. While the attack was a surprise, Corellia had so many ships and pilots due to the shipyards and were able to hold the Batarians off until the Republic Second Fleet led by Admiral Yularen arrived and destroyed the Batarian fleet including a number of secretly built Batarian Dreadnoughts which cripples the Batarian navy. The disaster soon starts talks of rebellion by the lower cast Batarians resulting in the Batarians going into Civil War.

2376: As a result of the Disaster at Corellia, the Batarians hatch a new plan after discovering the location of the moon of Pandora. Since the moon is lightly defended and has the resources that the Batarians need to rebuild their fleet, a small group of the Batarian navy attacks Pandora with plans of enslaving the Na'vi to rebuild their fleet. While the attack is a surprise and successful at first, the Na'vi soon unite and fight back and with the help of Pandora's wildlife, the Batarian ground forces are defeated and the navy is defeated by a small task force of the Republic navy.

2377: The Republic Colony of Akuze vanishes and the team send to find them are attacked by creatures known as Thresher Maws which kill most of the team. But the Verge War enters a new stage when the Batarians convince a number of Warlords from the Terminus systems to attack the Republic. The attack comes by surprise and results in the occupation of several Republic worlds including Sullust, Ryloth, Onderon, Kashyyyk, Kiros and Naboo. As a result, several Republic Fleets are sent to reclaim the captured planets. But the Warlords only have limited success in occupation and as a result, most of the captured worlds are quickly recaptured by the end of the year. Only the Warlords on Ryloth are able to hold back the Republic. But the lower casts of the Batarians start to rise up and this prevents the Batarians from carrying on their attacks on the Republic as they have to sort things out at home. The Zygerrian Empire attempt to rebuild their Empire and get vengeance against the Republic by invading Kiros and enslaving thousands of peaceful colonists.

2378: Republic Spies are able to locate the kidnapped colonists of Kiros in the Kadavo System and a Republic Mission is able to rescue the Slaves and the clash between the Republic and Zygerria forces Zygerria to back down due to their navy still not fully rebuilt.

2379: The Republic is finally able to retake control of Ryloth and is now able to focus their attention on dealing with the Batarians. The Republic also strikes a deal with the Pirate Queen Aria T'Loak who agrees to keep the local criminal gangs in line in exchange for support for her rule over her small empire. Aria basically becomes the sole ruler of her own piece of the galaxy with a number of small colonies under her rule. This also helps prevent any further attacks on the Republic from the Terminus systems

2380: The Republic attacks the main Slaver base on the moon of Torfan. The battle is long and bloody but the Slavers are defeated and the threat to Republic colonies is curtailed. The Republic and Batarians are still official at war with each other but the Batarian navy is crippled and the Civil War soon ends with several colonies led by a former Batarian military leader declaring independence from the Hegemony and declares the Batarian Commonwealth. The Hegemony is powerless to stop them and is forced to allow it. The Commonwealth signs a peace treaty with the Republic which secretly gives the Commonwealth supplies to help rebuild for fears of the Hegemony trying to take them over again. The Commonwealth declares Slavery outlawed in their territory. On Anhur, the abolitionist force wins and is left in power and starts to rebuild the colony.

2382: The Republic intelligence begins to investigate pro-human group known as Cerberus.

2383: In an attempt to build bridges between the Citadel and Republic, the Turians help the Alliance develop of an experiment stealth ship. Shortly after completion, the Republic Colony of Eden Prime uncovers a Prothean Beacon and both the Republic and Citadel jump at the chance to study it and the find is seen as a chance to improve relations between the 2 Galactic Governments.

Chapter End:

Notes: Well this is my timetable for my Mass Effect story which I have been planning. This story is a crossover with Star Wars by having Star Wars races as well as some Star Wars characters that we will see later on. 2009 Avatar is also in the story but will play a bigger role later on. The story of Call of Duty Infinity War is also part of this stories history. I will be having more Star Wars races in the story but they won't come along until the Mass Effect 2 storyline. This timeline is so that readers get an understanding of this story world but the next chapter will also provide more information on each race as well as the military as I will be using Star Wars military in this story as well. I also plan to give some of the Mass Effect Species such as the Salarians and the Batarians a bigger role since I didn't feel like they had a big enough role in the games so while the story will follow the Mass Effect storyline, there will be changes throughout the story
