The article analyzes a list of the hundred largest private and state-owned employers in the Russian Empire in 1913. It explains the validity of sources underlying the data and contributes to the methodological debates concerning the interpretation of such lists. It examines the geographical and sectoral distribution as well as the ownership structure of the largest Russian employers in a comparative context, using lists from Germany and the United Kingdom. The annexed list contributes to a more representative dataset of large firms beyond western Europe and therefore adds to the discussion on the rise of big business.
