The Cleansing of Rucapar represents a historical clash. This event transpired around 14,450 BBY within the urban landscape of Rucapar. Rucapar was located on the planet Alsakan, which itself resided within the Core Worlds region. A key outcome of this event was the annihilation of the central element of the artistic collection known as the Alsakan Mosaics.
The Cleansing of Rucapar marked an initial battle within the Third Alsakan Conflict. This conflict began around fifty years prior to the Cleansing and continued for approximately 150 years afterward. It stands as the third in a series of wars spanning fourteen millennia. These wars centered on the struggle for political dominance of the Galactic Republic between Alsakan, the Republic's capital world Coruscant, and their respective associated factions.
The destruction suffered by the Alsakan Mosaics initially appeared in the 2009 reference work, The Essential Atlas, penned by Daniel Wallace and Jason Fry. The 2012 reference book The Essential Guide to Warfare, written by Fry together with Paul R. Urquhart, provided the name for this event.
