Timeline:
Unknown BCE
The Leviathans dominate the galaxy, enthralling every new sapient race they encounter and protecting them in return for tribute. The Leviathans consider themselves the galaxy's first and only apex race.
After observing that their subservient races create synthetic races who consistently and violently rebel, the Leviathans create an Intelligence to seek a way to permanently preserve organic life. The Intelligence constructs an army of "pawns" to gather genetic information throughout the galaxy.
The Intelligence betrays the Leviathans, using its pawns to slaughter them for their genetic material to create Harbinger, the first Reaper. Thus begins the cyclical harvest of the galaxy's intelligent organic life by the Reapers, part of a vast experiment conducted by the Intelligence to fulfill its mandate.
The Intelligence builds the mass relay network to increase the efficiency of the cycles, allowing galactic civilizations to develop faster and more consistently between harvests.
1,000,000,000
The Leviathan of Dis, a Reaper, is killed by the Leviathans. Its corpse comes to rest on the planet Jartar and remains undisturbed for nearly one billion years.

37,000,000 BCE

About 5 million years Before Age
The evil wizard Bibidi creates Majin Buu. Majin Buu destroys thousands of planets in the following years. Four of the five Supreme Kais are killed. South Supreme Kai and Grand Supreme Kai are absorbed by Buu adding an aspect of good to him and changing his appearance. East Supreme Kai manages to kill Bibidi and leaves Buu's shell on Earth.
298,000 BCE
The ancient arthenn race flourish in the Zelene system, living on the planet Helyme until being destroyed in an unknown event that wiped out all complex life on the planet. They also maintained a presence on other planets in the system including Epho, which bears the scars of an ancient orbital bombardment, and Gaelon, which may have been mined for helium-3.
125,000 BCE
Ancient spacefaring races called the thoi'han and inusannon fight over the planet Eingana, littering the planet with the debris of hundreds of starships. Refined element zero scattered by broken drive cores contaminates the environment, causing many native species to go extinct and those that survive to show a tendency to develop biotic powers.
68,000 BCE
The Protheans achieve spaceflight and discover mass effect technology from the ruins of the extinct inusannon. They go on to establish a galaxy-wide civilization linked by the mass relay network with the Citadel as their capital.
At some point, the Protheans encounter a hostile race of machine intelligences that endanger their existence. To combat this threat, the Protheans aggressively assimilate many other spacefaring organic races into their empire. The Prothean Empire is able to fend off the machines in a conflict known as the "Metacon War".
48,000 BCE
The Prothean Empire collapses with the arrival of the Reapers through the Citadel. Although the Protheans had learned of the Reapers' existence from studying the ruins of previous civilizations and had begun to prepare, they were nonetheless caught off-guard. Over the next several centuries, the Protheans fight the Reapers system by system, world by world, and city by city. In the end, it is not enough. The Reapers methodically wipe out the remaining Protheans, as well as other contemporary races, and depart the galaxy to await the next cycle.
13,000 BCE

6000 BCE
Seeking to escape the imminent explosion of their sun, an alien race constructs and AI-managed starship equipped with supercomputers containing a virtual world, into which some one billion of the aliens transfer their consciousness. The starship begins a journey throughout the galaxy for the next 8,000 years.
1900 BCE
Tunchanka, the krogan homeworld, enters the nuclear age. In a global conflict weapons of mass destruction are released, triggering a nuclear winter. In the resulting devastation, krogan society devolves into a collection of warring clans.
1800 BCE
A supernova propels the Mu Relay, the only point of access to the remote Pangaea Expanse, out of position. Concealed somewhere in the dense nebula formed by the supernova, the relay's position is effectively lost for centuries. Later, the rachni rediscover the relay.
580 BCE
After developing faster-than-light spacefaring capabilities based upon Prothean technology, the asari begin to explore the mass relay network, and eventually discover the huge Citadel space station at a hub of many mass relays.
520 BCE
The salarians discover the Citadel and open diplomatic relations with the asari.
500 BCE - 1 CE
The Citadel Council is formed. The Asari and Salarians together colonize the Citadel and establish it as a center of the galactic community, led by the council. This year is also known as 0 GS, the beginning of the Galactic Standard timeline.
As a gesture of openness with their new asari allies, the Salarian Union opens the records of the League of One. Under threat, the League responds by assassinating every member of the Union's inner cabinet; Special Tasks Group (STG) operatives then hunt down and eliminate the League.
First contact is made with the volus. Eventually the Citadel Council commissions the volus to draw up the Unified Banking Act, which establishes a standard galactic currency known as the credit and links all galactic economies.
The turian Unification War occurs. The increasingly isolated and xenophobic colonies on the frontier of turian space go to war with each other. After years of fighting the Turian Hierarchy sweeps in and pacifies the remaining factions. Animosity between turian colonies continues for decades.
The Council grants the volus the honor of being the first non-Council species with an embassy at the Citadel, rather than a Council seat.
First contact is made with the batarians. They are granted an embassy a century later.
The asari discover the elcor home system and help the elcor locate and activate their nearest mass relay. "Within one elcor lifetime" they establish a regular trade route to the Citadel and are granted an embassy.
First contact is made with the hanar and the quarians. Both races are later granted embassies.
1 CE/1338 Before Age
In the first year marking a new era for the entire universe, war breaks out. The Rachni, a species of highly advanced hive-minded species, are discovered when a citadel expedition opens a dormant mass relay leading to their star systems.

Negotiations with the rachni queens is impossible because they cannot be contacted in their underground nests on the toxic rachni worlds.

The Citadel Council makes first contact with the turians around this time and persuade them to aid in the war. After the krogan respond to the initial turian offensive by devastating turian colonies with weapons of mass destruction, the turians vow to stop the krogan from ever becoming a threat again.
Sometime after the turians join the galactic community, the volus are accepted as a client race of the Turian Hierarchy.
710 CE/629 Before Age
