On 6th January 1926 by merging Deutsche Aero Lloyd and Luftverkehr there was established a new company called Deutsche Luft Hansa. It was the biggest German passenger carrier during the interwar period. After the outbreak of World War II Deutsche Luft Hansa limited its field of activity to neutral or allied countries or conquered territories. The enterprise was closed in 1951. Contemporary Lufthansa Airlines despite similar name and repurchasing part of its estate is not its legal heir.
