The species developed their first nation-states in 800 BC. (Last Unicorn RPG module: All Our Yesterdays: The Time Travel Sourcebook) First contact between humans and the Axanarri occured in 2151, when the crew of the Enterprise (NX-01) encountered an Axanarri vessel following an attack by an unknown species on an Axanarri vessel. The unidentified assailants were "harvesting" triglobulin from the ship's crew. The Axanarri originally suspected that the Enterprise crew were responsible for the attack, but Ensign Hoshi Sato was able to communicate the truth to them. (ENT episode: "Fight or Flight")
