The battle of Corellia, took place in 4,022 BBY in the Core Worlds Campaign during the Republic-Mandalorian Wars. After gaining foothold in Corulag, the Mandalorian armies were preparing for a long-thought campaign which was issued by both Darth Admer and Mandalore the Deceived which were supposed to lead the Mandalorian Empire to a decisive victory against the Jedi. The battle was the beginning of a series of hit and run assaults, which destroyed all the Galactic Jedi Republic resource production factories and mines, which would lead to them taking control over civilian resource production, thus causing anti-republic operations and uprisings to begin planet wide. Eventually, the population decided to join the Mandalorian Empire and banish every republic presence from their systems.
