An estimated 100,000 German Jewish military personnel served in the German Army during World War I, of whom 12,000 were killed in action. The Iron Cross was awarded to 18,000 German Jews during the war.
While strong attempts were made during the Nazi era to suppress the Jewish contribution and even to blame them for Germany's defeat, using the stab-in-the-back myth, the German Jews who served in the German Army have found recognition and renewed interest in German publications.
German Jews serving in the military predates the formation of the second German Empire in 1871, Jews having served in the Prussian Army in the German Campaign of 1813, the "Wars of Liberation". Meno Burg became the highest ranking German Jew in the Prussian Army in the 19th century, reaching the rank of Major. Jews continued to serve in the Prussian Army during the Second Schleswig War (1864), the Austro-Prussian War (1866), and the Franco-Prussian War (1870–71). After the establishment of the Empire in 1871, Jews in the Prussian Army did not receive the anticipated equal rights; they were barred from government positions and officer ranks, while other German states like Hamburg and the Kingdom of Bavaria were more liberal. Between 1880 and 1910, up to 30,000 German Jews served in the Prussian Army, but none were promoted to the rank of officer. However, among the 1,500 Jews who converted to Christianity, 300 were promoted.
With the outbreak of World War I in 1914, the situation drastically changed for German Jews in the military. At the start of the war, 12,000 German Jews volunteered for the German Army. Of the 100,000 Jews who served with the German military, 70,000 fought at the front line, 12,000 were killed in action, and 3,000 were promoted to officer ranks, but they could only become officers of the reserve, not the regular army. The Iron Cross was awarded to 18,000 German Jews during the war, of which 1,000 received the first class award. Jewish-born Wilhelm Frankl became the first member of the flying corps to be awarded the Pour le Mérite. The anti-semitic Judenzählung of 1916 disgusted many German Jewish soldiers, being aimed at falsely proving that Jews were trying to avoid military service. For many German Jews, the war held the hope of being treated equal to non-Jewish Germans for the first time. Many Jews also held strong patriotic feelings for Germany and the belief that the war in the East against the Russian Empire would bring the liberation of their fellow Eastern European Jews from pogroms and persecution.
