Herbert Backe was born in Batumi, Georgia, the son of a retired Prussian lieutenant turned trader. His mother was a Caucasus German, whose family had emigrated from Württemberg to Russia in the early 19th century. He studied at the Tbilisi gymnasium (grammar school) from 1905 and was interned on the outbreak of World War I as an enemy alien because he was a citizen of Prussia. This experience of being imprisoned for being German and witnessing the beginning of the Russian Revolution made Backe an anti-communist.
