The years after the formation of the Jedi order and the time which they split into different factions (Sith and Ordu Aspectu). This is the first era of recorded history under early galactic governments.
The original Galactic Republic was formed in approximately 25,000 BBY on the urban world of Coruscant and rose to power by expanding across the galaxy, with several of its founding members being the planets Alderaan and Chandrila.
The Jedi were an order of ancient origins, having been present in the galaxy for over one thousand generations. Originally established at the first Jedi Temple on Ahch-To by the Prime Jedi, the Jedi Order established numerous sites throughout the galaxy on Coruscant, Ossus, Tython, and Jedha. The Jedi eventually came to align with the democratic Galactic Republic and owed their allegiance to the Galactic Senate.
A conflict was fought by the Jedi Order against the Zygerrian Slave Empire to end their slaving operations after they were outlawed in Republic space. Their defeat left many Zygerrians such as Darts D'Nar and Atai Molec with a seething hatred of the Jedi.
he Hundred-Year Darkness was a period of time that led to the formation of the Sith, who were once considered brothers in the Force with the Jedi Order. The birth of the Sith led to a number of wars over the course of galactic history.
The Entruvia Conflict was a war fought when the Domancion Accord was still employed as an epoch, between the Jedi Order and the Ordu Aspectu, a splinter sect. Eventually, a peace treaty was signed, which allowed the orthodox Jedi to inspect the Ordu Aspectu's work for signs of dangerous heresy.
The doom of the Ordu Aspectu was a battle that took place many years before the Battle of Yavin between the Jedi Order, Ordu Aspectu (a Jedi splinter group.), and droids controlled by Eternal Rur.
The Jedi declared war on criminal syndicates and pirates to halt their increasingly threatening presence in the galaxy.
According to the myths, the Great Hyperspace War was initiated when the Sith Empire invaded the planet Empress Teta, formerly Koros Major, which had recently been conquered by Empress Teta. After the outbreak of the Great Hyperspace War, Teta supposedly worked alongside the Jedi Order to fight against the Sith, successfully driving back the Sith Lord Naga Sadow and scattering the Sith forces across the galaxy. The Jedi Master Ooroo was involved in the Great Hyperspace War, perishing at some point during the conflict. While the inhabitants of Empress Teta presented the events of the Qel-Droma Epics, including the Great Hyperspace War, as historical fact, archaeological expeditions failed to verify the legends.
During a war against the Jedi Order, the Sith took control of the planet Coruscant, the capital world of the Old Republic. During their occupation, the Sith constructed a shrine over a dark-side vergence on the planet. The Jedi laid a siege to the shrine, burning it to its foundations and defeating the Sith. After this substantial victory, the Jedi build a new temple over the remains of the Sith shrine, in an attempt to rid the planet of Sith energy, and pledge their service to the galaxy as enforcers of peace in the newly formed "Galactic Republic."
The Jedi encounter the Mandalorians and immediately fall into a large scale conflict.
