Pax Republica: A Star Wars MUSH

The first Jedi establishes the beginnings of the Jedi Order on the remote planet of Ahch-To.

Shortly after the founding of the Jedi Order, the planet Ilum is discovered by Jedi scouts, and the first Kyber crystals are discovered.

The "Old" Galactic Republic is formed by the ratification of the Galactic Constitution in the Core Worlds, creating a union between Coruscant, Corellia, Alderaan, Duro, Brentaal, Caamas, and Kuat, among others.

The Republic undergoes a period of expansion as it colonizes the planets of the Inner Rim, which become known as The Colonies. Over time, several of these worlds establish themselves as important centres, due to their resources, political value, or strategic locations along critical hyperspace routes. The majority of worlds in The Colonies are agricultural or mining worlds.

The Temple of the Kyber is constructed on the cold desert moon of Jedha

A conflict between the Jedi Order and the Zygerrian Slave Empire results in a Jedi victory.

A rogue Jedi named Ajunta Pall is exiled from the Order for his belief that the Dark Side of the Force was the path to true power; Pall gained followers and formed a new sect of Force users which would eventually become the Sith. The ensuing period of war between the Jedi and Sith Orders is referred to by Jedi historians as the Hundred-Year Darkness. After a century of fighting, the Jedi defeat the Sith, who retreat from known space to the planet Moraband.

After a long period of rebuilding, the Sith re-appear in the galaxy as the Sith Empire under the command of the Dark Lord of the Sith, Naga Sadow. The Sith easily conquer nearby systems, until they attempt to invade the Koros sector, where they are rebuffed by the forces of Empress Teta with the help of the Jedi Order, and they retreat back to Moraband.

The Great Jedi Library is constructed on the planet Ossus, and Jedi philosophers and historians gather there to further their knowledge and study of the Light Side of the Force. Ossus had been the Jedi's cultural centre for thousands of years at this point.

Following their defeat in the Koros sector, the Sith rally their forces and invade the Core Worlds, sparking war with the Republic itself. Their forces are much more powerful than the Jedi and the Republic were led to believe based on their attack on the Koros sector, and the Sith are able to overwhelm their enemies and take control of Coruscant and occupy many of the Core Worlds. The Sith construct an immense shrine atop a Dark Side vergence on a mountain at the heart of the planet.

After fifty years of Sith occupation of the Core Worlds, the Republic and the Jedi are able to rally and drive the Sith out. In the aftermath of the war, the Jedi destroy the Sith Shrine, razing it to its foundations in an effort to literally and figuratively bury the Sith legacy. The Sith are driven back to the Outer Rim, and the Republic and the Jedi focus on rebuilding and recovery.

The Republic and Jedi come into contact with Mandalorian Crusaders conquering neighbouring systems. Following their initial encounter with the Force-using Jedi, the Mandalorians develop weapons and armor designed to combat them. Over the following millenia, conflict between the Mandalorians and the Jedi, as well as the Republic, is frequent enough that historians refer to it as the Mandalorian-Jedi War. There are few large scale battles until the final battle, during which the surface of the Mandalorian homeworld is scorched by a massive cataclysm, rendering the world all but uninhabitable outside of a handful of sealed dome cities. In the aftermath of the conflict, the Mandalorians are sequestered on their ruined planet, and made to pay reparations to the Republic and the worlds they devastated during the crusades.

Several stars in the Cron Cluster suddenly go supernova, devastating the region and creating the Cron Drift. As a result of these explosions, the planet Ossus is all but destroyed, its surface rendered largely uninhabitable and all life wiped from the planet.

The Jedi Temple on Coruscant is constructed over the ruins of the destroyed Sith Shrine, by the then-leaders of the Jedi High Council who come to be known as The Four Masters. As the Jedi Order becomes might rightly linked to the Republic, the Jedi Temple is expanded several times over the centuries to accomodate its growing importance.

The Sith and Jedi battle over the planet Malachor, where the Sith have been developing kyber-based superweapons. When defeat of the Sith seems imminent, the weapon housed in the Sith Temple is activated, killing every living thing on the planet, leaving the petrified remains of thousands of Jedi and Sith behind. Following the event, the Jedi are forbidden from travelling to Malachor, and the world's location is wiped from Republic and Jedi archives.

The Sith are finally defeated as infighting between the Dark Lords of the Sith weakens their Empire. The Jedi fight the Sith on Moraband to the last man, and when the battle is over the Sith are believed to have finally been destroyed in their entirety.

For nearly 1000 years, the power and influence of the Republic had declined under a stagnant bureaucracy, political corruption, and demoralized citizenry. Following the end of the Jedi-Sith War, the Old Republic finally collapsed under its own weight, entering a period during which individual systems and worlds retreated into themselves, distancing from the galactic community.

The Galactic Republic is re-organized and reformed, and the galaxy enters a period of peace known as the Republic Era, characterized by a lack of galaxy-spanning wars. Among the reformations is the demilitarization of the Republic, and the elevation of the Jedi High Council as a direct advisor to the Chancellor and Senate, and the Order tasked with peacekeeping duties throughout Republic space. The Jedi Temple on Coruscant is expanded, and serves as the Order's operational and spiritual headquarters.

Yoda is born on an unknown planet. It will be nearly 100 years before he joins the Jedi Order to begin his training.

The planet Naboo is officially admitted to the Galactic Republic. Within five years, the city of Theed is established, and the Theed Royal Palace is constructed as its seat of government.

The Antarian Rangers are founded on Antar IV as an auxiliary force to assist the Jedi in their peacekeeping efforts.

Jabba the Hutt is born on Nal Hutta

Improvements in hyperspace technology lead to the discovery of new hyperspace routes connecting more of the Outer Rim, and the Republic enters a period of expansion and exploration. Scouts are recruited to further explore unknown space and discover new worlds for the Republic to colonize and exploit, leading to contact with previously unknown species; over the next century the edges of what is considered to be the Outer Rim are pushed further and further from the Core Worlds.
