Although Daimler-Benz is best known for its Mercedes-Benz automobile brand, during World War II, it also created a notable series of engines for German aircraft, tanks, and submarines. Its cars became the first choice of many Nazi, Fascist Italian, and Japanese officials including Hermann Göring, Adolf Hitler, Benito Mussolini and Hirohito, who most notably used the Mercedes-Benz 770 luxury car. Daimler also produced parts for German arms, most notably barrels for Mauser Kar98k rifles. During World War II, Daimler-Benz had over 60,000 concentration camp prisoners and other forced laborers to build machinery. After the war, Daimler admitted to its links and coordination with the Nazi government.
