The planet formerly was an Earth Federation colony that broke away during the Sol Gamma Wave in 2601. It later was conquered by the Republic during the Annexation of the Western Territories in 2743, the Republic's annexation of the 27 independent colony worlds that dominated the space to its galactic west.
The planet rebelled during the Lovejoy Revolution and broke away in May 3073 during the Cessation of the Western Territories. It allied with the other rebelling worlds, forming the Western Confederation of Independent Worlds.
The planet was not ironically named after the Buchenwald concentration camp, a German Nazi concentration camp established Weimar, Germany, in July 1937, one of the first and the largest of the concentration camps on German soil. It was in fact named for the Buchenwald Resistance , a resistance group of prisoners inside the concentration camp. It involved Communists, Social Democrats, and people affiliated with other political parties, unaffiliated people, and Christians. The captain of the colony ship EFS Princess Mafalda was a direct descendant of the Buchenwald survivor Gert Schramm .
