Yeah, well I'm sorry, I get a little testy when faced with the total annihilation of our little corner of it."

The Milky Way (a translation of the Latin Via Lactea, in turn derived from the Greek Kuklos Galaktikos), or Avalon by the Ancients, is a galaxy in the Local Group. It is home to several species influential to the history of the known universe, including the Goa'uld, the Tau'ri, and the Replicators.
The Milky Way galaxy is also one of a few known galaxies with a functional Stargate network, the others being Pegasus, Ida, the Alteran Home Galaxy and all of the other galaxies visited by the Destiny and her sister ships.
Millions of years ago, the Milky Way was colonized by the Ancients after they fled their home galaxy. They first landed on a planet they called Dakara. They later landed on Earth which they called Terra, the center of the Ancient presence in the galaxy, it was used as the reference point for the Stargate network, with the coordinate system inspired by constellations as seen from Earth.
Approximately five to ten million years ago, a virulent plague infected the Ancients that nearly wiped out the species. Originating at the construction site for their new capital known as Vis Uban, the deadly disease would spread across much of the galaxy. They attempted to travel back in time, to stop the plague from spreading, but their efforts were unsuccessful. Unable to cure it, the surviving Ancients left Earth in a huge space-borne city, which they called Atlantis.
Before leaving, the Ancients reseeded the Milky Way with human life with the Dakara superweapon. As a result of this intervention, the Tau'ri — the "second evolution" of the Ancients — evolved on Earth. By 9,177 BC, they developed primitive societies in isolation from the rest of the galaxy, as a result of not having access to the planet's original Stargate, which was buried under ice in the uninhabited Antarctica. This changed when the Goa'uld System Lord Ra discovered the planet and brought a second Stargate to transport Tau'ri slaves to Goa'uld-controlled planets.
By 3,000 BC, the Goa'uld had seeded the Milky Way galaxy with various human races descendant from the Tau'ri, most prominently the Jaffa. It was at this point that the Tau'ri back on Earth rebelled against Ra forcing him to abandon the planet. The humans then buried the gate.

20th Century onwardsEdit
Ra's Stargate lay buried until it was unearthed in 1928. In 1996, the Tau'ri activated their Stargate, and their first off-world expedition to Abydos, led by Colonel Jack O'Neill, confronted and killed Ra. This event created a power vacuum in the System Lords ranks, triggering a chain of events that eventually led to the downfall of the Goa'uld as the dominant power in the Milky Way. (Stargate)
In 2006, the enemy that was responsible for the Ancients fleeing to the Milky Way and presumably the plague that wiped out most of the Ancients, the Ori, started a massive crusade in this galaxy. After two years of war, the Ori were finally destroyed by SG-1 with some help from Morgan Le Fay who defeated Adria. The Priors of the Ori were made to believe truth about the Ori, that were not true gods, following the activation of the Ark of Truth, effectively ending the war in the Milky Way. Later, Ba'al, the last remaining System Lord was eliminated, removing the Goa'uld threat forever apparently. (SG1: "The Ark of Truth", "Continuum")
