The Axanarri have a long history with the human species; their homeworld was colonized by the United Earth Government, and was designated Beta Gabriel. The Axanarri fought the encroaching humans several times for control of their homeworld before the two species were forced to fight side-by-side during the Human-Covenant War. Axanar itself was partially glassed by the Covenant and occupied in the aftermath of their defeat during that conflict. Following the Human-Covenant War, the Axanarri would join humanity in forming the Alliance of Free Stars to contest the Ur-Quan Hierarchy of Battle Thralls during the First Ur-Quan War. When the Hierarchy was eventually defeated, the Axanarri, hardened after several centuries of conflict and oppression at the hands of alien races, isolated themselves around their homeworld, cutting off all contact with their neighbors, particularly the UEG. Eventually, this period of isolation ended, and the Axanarri and humans finally made peace, with the former eventually joining the United Federation of Planets.
