During the Mandalorian Wars, specifically in 3962 BBY, the Mandalorian Neo-Crusaders and forces of the Galactic Republic clashed in combat on Azure, a planet previously raided by the Mandalorians. This confrontation occurred as the Mandalorians, launching an offensive from their own space known as Mandalorian Triumph, sought to seize the Core World of Duro. The planet Eres III was their initial target and was devastated, after which they achieved victory on Azure. Subsequently, they attacked Contruum before advancing further into the Core Worlds.
Vilnau Teupt gave the keynote address at the four hundred and twelfth Proceedings of Galactic Anthropology and History in 24 ABY, and during his discussion on the Mandalorian people's evolution, he referenced the Mandalorian Wars, specifically mentioning Mandalorian Triumph and the engagement on Azure.
The battle's initial mention occurred within The Essential Atlas, a work penned by Daniel Wallace and Jason Fry that saw release in 2009. The galactic map included in the Atlas showed the Azure system as one of the systems where battles took place during the Mandalorian Wars.
