The Star Wars Timeline
13,000,000,000 BBY – 25,053 BBY
The Pre-Republic Era, also known as the Early Hyperspace Age, was the period before the formation of the Galactic Republic. It included the formation and evolution of all the species of the galaxy, the dawn of their civilizations and their first developments in space travel, and ended in approximately 25,053 BBY, when the Republic was founded.
The Expansionist Era, also known as the Expansion Period or the Galactic Expansion Era, was the term given to the years after the Galactic Republic formed, when transit between the Core Worlds was opened up by the newly-developed hyperdrive, and during the early expansion of the Republic. Also, the Tion Hegemony, at this time, was a proud civilization, and most of the worlds of the Allied Tion sector were settled.
The Myneyrsh–Psadan wars and the Wayland colonial war were fought on Wayland during this era, as well.
Great Manifest Period
20,000 BBY–17,018 BBY
The Great Manifest Period of the Galactic Republic, is marked by the increased movement into the Rimward territories of the Slice, which became known as the Expansion Region.
The Republic expanded astrographically and so did its bureaucracy. The limit of fifty systems per sector that had been set by the early Republic is ignored, causing sectors in the newly colonized areas of galactic space to be ungovernable.
The Era also saw the creation of the Metellos Trade Route, which connected Coruscant to Metellos and other points west of the galactic center. The new hyperspace route increased trade among the newly connected systems.
The Indecta Era
The Indecta Era was the period of time from 17,018 BBY to 15,000 BBY.
The period was noted for the introduction of assassin droids used by the Judicial Department.
The Kymoodon Era marked a second boom in expansion similar to the Great Manifest Period. Hyperspace travel became more commonplace during this time and some of the most noted starship manufacturers were founded.
In the last centuries of the era, Republic colonists spread beyond the frontier into what was then the Wild Space between the Republic and Hutt Space. The Hutts sponsored numerous raids against these planets with the aim of enslaving the colonists. Lexrul, Drogheda, Hathrox, Imram and Parcovey Minor were among those colonies targeted. The successful defense of Parcovey Minor was one of the few bright spots for the colonists amid the raids.
Pius Dea Era
During The Pius Dea Era, the Contispex dynasty of Supreme Chancellors initiated the Pius Dea Crusades against outlying alien cultures, reversing a previous trend of cultural integration. Those under persecution fled to Hutt Space, transforming the Rimward Slice into a staging grounds for soldiers, as well as an area for war profiteers to operate.
Also during this time, Ordnance/Regional Depots proliferated and were a constant reminder to those outside the Galactic Republic.
10,966 BBY–9000 BBY
The Ductavis Era was an era of time in the galaxy from 10,966 BBY to 9000 BBY. It was considered a time of rebuilding after the crusades of Supreme Chancellor Contispex I during the Pius Dea Era.
The Rianitus Period of history lasted from 9000 BBY to 8000 BBY. It was remembered for the 275-year reign of Blotus the Hutt. Around the end of this period (c. 8000 BBY), the Republic established an outpost on Malastare’s eastern continent.
During The Subterra Period, there was a new mapping of the galactic southern quadrant. The planet of Malastare acted as an anchor for short hyperlane snippets, also known as praediums. The supply lines that linked the galaxy with the Rishi Maze were also constructed.
The rapid expansion led to lawlessness in the Rim and Coruscant lost its control on its new territories. This was thought to have contributed to the Second Great Schism in 7003 BBY, which led to the start of the Hundred-Year Darkness.
The Manderon Period was marked by a “trio” of discoveries which changed the fate of the galaxy.
The Hundred-Year Darkness is fought during the first century of this period.
According to legend, the Mandalorian Crusaders were formed around the beginning of this period on the planet Mandalore by the Taung, Mandalore the First.
The Exiles discovered the Sith Empire. The Corellian Trade Spine was completed by 5500 BBY. Simultaneously the Herglics and Givin form the Rimma Trade Route out of pre-existing praediums.
This time period, following the Manderon Period, lasted until the outbreak of the Great Sith War that marked the beginning of the Old Sith Wars in 4000 BBY.
The Great Hyperspace War, between the Galactic Republic and the Sith Empire—erupts when two young hyperspace scouts, Gav and Jori Daragon, accidentally make contact with the Sith.
