The year 12,000 before the Battle of Yavin (BBY) was a span of time that featured continued expansion of Galactic Republic boundaries. Explorers and settlers had been continuously and steadily expanding the boundaries of Republic space in the years prior. Around 12,000 BBY, explorers and colonists from Corellia established a settlement on the planet Ord Mantell, a world in a previously unexplored area of the Mid Rim. There, the settlers created an advanced military outpost.


During the years of the Old Republic, the governing body gradually but steadily expanded its boundaries. Most of the settlements, however, were in a wedge-shaped region of space known as the Slice. Aside from occasional protrusions into unknown areas and isolated settlements, most of the galactic society lived within the confines of known hyperspace routes and the established hyperlanes. Settlers and explorers, however, continued to search the wild and unexplored areas of the galaxy. In the years leading up to 12,000 BBY, this steady advancement continued.[1]

The expansion of the Republic continued around 12,000 BBY as colonists from Corellia continued to explore uncharted space. A group of colonists settled on the Mid Rim world of Ord Mantell. The colonists established an advanced military outpost on the planet for the expanding Republic, even though it was isolated from Republic space by uncharted area.[1] This planet was an Ordnance/Regional Depot (Ord) world whose purpose was to also protect Human colonists in the surrounding systems. Elsewhere, the Ithorians of Ithor had their first contact with the Republic, further expanding the reaches of known space.[7]

Notable events[]

Notes and references[]

  1. 1.0 1.1 1.2 1.3 The New Essential Chronology
  2. The Essential Guide to Warfare establishes the endpoints of this era as 15,000 BBY and 11,987 BBY.
  3. SWTOR mini.png Galactic History on The Old Republic's official website (article) (backup link) dates the Tho Yor Arrival, as described in Star Wars: Dawn of the Jedi 0, to the year BTC 32,800 of the calendar based on the date of the signing of the Treaty of Coruscant. Since the difference between that calendar and the Galactic Standard Calendar—based on the date of the Battle of Yavin—was 3,653 years per the reasoning here, the Tho Yor Arrival must have taken place in the year 36,453 BBY of the latter dating system. Therefore, the difference between the Galactic Standard Calendar and the dating system based on the Tho Yor Arrival that is featured in Dawn of the Jedi: Into the Void must be 36,453 years.
  4. Star Wars: The Old Republic Encyclopedia places the Treaty of Coruscant, which served as the zero point of a calendar adopted by the Galactic Senate following the conclusion of the Great Galactic War per SWTOR mini.png Galactic History on The Old Republic's official website (article) (backup link), in the year 3653 BBY of the Galactic Standard Calendar, which was based around the date of the Battle of Yavin. Thus, the difference between the two dating systems is 3,653 years.
  5. The New Essential Chronology establishes that the zero point of the calendar introduced by Tarsus Valorum was the Ruusan Reformation. The book places that event in the year of 1000 BBY of the Galactic Standard Calendar—which was based around the date of the Battle of Yavin—therefore establishing a difference of one thousand years between the two dating systems.
  6. The Essential Atlas places the Battle of Yavin, the zero point in the Galactic Standard Calendar per The New Essential Chronology, in 35:3 under the Great ReSynchronization dating system. The Essential Atlas also places the Battle of Selaggis on 43:2:28 and the Battle of Dathomir on 43:3:21. The Essential Guide to Warfare and The Essential Atlas both place the Battle of Dathomir in the year 8 ABY of the Galactic Standard Calendar. The Essential Guide to Warfare also places the Battle of Selaggis in 7 ABY, confirming the placement of the division between each Galactic Standard Calendar year as the third month in the Great ReSynchronization year. Thus, there is a two-month gap between the two dating systems, with the first two months of a GrS year being the last two of the preceding Galactic Standard Calendar year, and there is a total difference of 35 years and 2 months between the two systems.
