19,000 before the Battle of Yavin (BBY) was a year in the Galactic Republic's Great Manifest Period. The era, having begun 1,000 years earlier, featured rapid expansion out from the Core Worlds and into the areas of Wild Space east of the galactic center. Outside the galactic disc, the isolated world of Kamino underwent a dramatic climate change. There, the surface ice began to melt and flood the planet, forcing the native sentient species to relocate their cities.


In the years prior to 19,000 BBY, the planet Kamino was a terrestrial world outside the galactic disc that featured only small narrow oceans. Landlocked, the oceans were overpopulated with eels and cetaceans that choked the waters. On land, small marshes and low-lying areas had given rise to the tall, sleek Kaminoan species. The natives developed cities along the oceanic coastal areas, such as the community Derem.[1]

The galaxy in 19,000 BBY[]

Around the year 19,000 BBY, Kamino began a dramatic climate shift. The surface ice, which was confined to the planetary glaciers, began to melt. As it melted, the low-lying marshes that gave rise to the Kaminoans and the narrow oceans began to flood, covering the then-extant land area. Elsewhere, in the Galactic Republic, the Great Manifest Period was continuing. The Republic continued its expansion and settlement of the areas east of the Core Worlds, into the area that eventually came to be known as "the Slice."[1]


Within two centuries, all the surface land on Kamino was buried under water, which was hundreds of meters deep at places. The former cities, such as Derem, and architectural wonders, such as the Clock Spires of Harai Nova, were submerged. For survival, the Kaminoans adapted the technology they possessed to build their cities on stilts above the water level. Furthermore, the Kaminoans turned to genetic engineering to preserve many of the species that drowned in the rising waters. In the broader Republic, the expansion of the Great Manifest Period continued for another 2,000 years, until the rival Core Worlds began a series of conflicts for supremacy.[1]

Notable events[]

  • Kamino's glaciers began to melt due to climate change.[1]

Behind the scenes[]

The year 19,000 BBY receives its only appearance in The Essential Atlas, published in 2009.[1] While the Great Manifest Period is outlined in other sources, such as The New Essential Chronology, the year 19,000 BBY is not specifically mentioned.[7] In the Atlas, the year is specifically mentioned in the discussion of the planet Kamino, where the detailing of the planet's climactic shift is documented. Elsewhere in the Atlas, the year is merely alluded to in discussion of the Great Manifest Period.[1]


Notes and references[]

  1. 1.0 1.1 1.2 1.3 1.4 1.5 1.6 The Essential Atlas
  2. The New Essential Chronology and The Essential Guide to Warfare established the endpoints of this era as 20,000 BBY and 17,018 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.
