The attainment of Latvian state independence in 1918 brought significant changes in politics, including language policy, which had an impact on all aspects of public life. This was the first time Latvian gained the status of the official language, which meant that it was to be used both in government and society. However, contact languages such as German and Russian continue to have a great influence on the further development of the Latvian language. In this paper, the role of German in educational and science communication is uncovered via the monthly journal of the Latvian Ministry of Education (Latvian – Izglītības ministrijas mēnešraksts, 1920–1939) in comparison to other contact languages. In the journal deals with educational topicalities of the time, it was also a place where scientific papers and popular science articles were published, as well as book reviews and book recommendations, mainly from the humanities and social sciences disciplines.
