Anton Ludwig Friedrich August Mackensen, was a German field marshal. He commanded Army Group Mackensen during World War I (1914–1918) and became one of the German Empire's most prominent and competent military leaders. After the armistice of 11 November 1918, the victorious Allies interned Mackensen in Serbia for a year. In 1920, he retired from the army. In 1933 Hermann Göring made him a Prussian state councillor. During the Nazi era (1933–1945), Mackensen remained a committed monarchist and sometimes appeared at official functions in his World War I uniform. Senior Nazi Party members suspected him of disloyalty, but nothing was proven against him.
