The Haakonian Order was an interstellar power in the Delta Quadrant which conquered Talax, Neelix's homeworld in 2356.
The Haakonians and Talaxians fought a decade-long, destructive war which ended with the deployment of the metreon cascade weapon on the Talaxian moon of Rinax. The weapon killed all three hundred thousand inhabitants of Rinax, vaporizing more than a quarter of a million people and leaving thousands of others to be eaten away by Metreon poisoning. After this event, Talax, which had previously been preparing for a Haakonian invasion, surrendered unconditionally to the Haakonian Order. (VOY: "Jetrel")
They were believed to still be in control of Talax in 2378. That year, Dexa remembered that the Haakonian occupiers on Talax "didn't treat Talaxians very well." (VOY: "Homestead")
Ma'Bor Jetrel at one point referred to his government as "my country".
