Mon Cala, also known as Mon Calamari or Dac, was an oceanic planet located in the Mon Calamari system, a binary star system positioned in the Calamari sector of the galaxy‘s Outer Rim Territories and The Slice.

Home to two sentient aquatic species, the industrious Mon Calamari and the prideful Quarren, Mon Cala was known for its shipbuilding industry, which produced beautiful and unique starships for various purposes such as pleasure cruises and deep-space exploration. The Mon Calamari ran the Mon Calamari Shipyards company, and the Quarren ran the Free Dac Volunteers Engineering Corps.

The planet was governed by a monarchy with the King of Mon Cala holding the title of ruler. The king also led the Mon Cala planetary defense services and was the judge in the Court Of Justice. The ruler was also tasked with keeping the fragile peace between the Mon Calamari and Quarren intact while ruling over the planet.

Mon Cala became a battleground for the galaxy wide Clone Wars after the assassination of King Yos Kolina. The Quarren took the opportunity to rebel against the Mon Calamari with aid from the Confederacy of Independent Systems while the Galactic Republic backed the Mon Calamari. After defeat to the Confederacy, the Gungan Grand Army came to the help of the Republic. During the end of the battle, Quarren and Mon Calamari joined forces to push the Confederacy from Mon Cala.

Mon Cala would play a vital role in shaping galactic history by its involvement in the Galactic Civil War between the tyrannical Galactic Empire and the Alliance to Restore the Republic, pledging the ships of its mercantile and exodus fleets to the cause of the latter. Mon Calamari vessels would play a key role in many battles and allow the Alliance fleet to meet the Imperial warships on a more even footing.

Mon Cala regrettably paid a steep price for its assistance to the rebellion, however; prompting the remaining population to adopt a policy of isolationism for fear of provoking another atrocity against the planet. Nevertheless, Mon Cala would once again pledge its ships to the cause of freedom in the form of Leia Organa’s Resistance, unwittingly bringing the attention of the First Order down on the water world.
