This paper focuses on the study of the activity of German consular institutions on the territory of Soviet Ukraine during 1922–1938. German consular representatives operating in Ukrainian cities were career diplomats, who had higher education, a perfect command of foreign languages, and deep knowledge in the fields of history, geography, statistics, political economy, and international law. While operating in Ukraine, German consuls were taking their official duties seriously: normalization of bilateral trade and economic relations, the establishment of cultural ties, as well as protection and assistance to German citizens living within the consular district. One of the important aspects of consular activity was the performance of the “honorary spy” functions.
