Following World War II, Friedrichshafen was part of the French occupation zone before its incorporation into Baden-Württemberg, West Germany. In the aftermath of the war, Maybach and many other aviation companies turned to automobile construction, while Claudius Dornier purchased Theodor Kober's failed Flugzeugbau Friedrichshafen and established Dornier Flugzeugwerke. Owing to the provisions of the Versailles treaty, many of the planes were initially produced in Italy, Spain, the Netherlands or Japan, but resumed work at its Friedrichshafen and other German factories following the rise of the Nazi regime. The 1937 Hindenburg disaster and a subsequent embargo on sending American helium to Germany, however, effectively ended the production of German dirigibles. The German aeronautics industry was again banned for many years after the war, and companies again failed or shifted production.
