The paper’s main goal is to analyse the impact of the Munich Agreement, the Vienna Award, and the Polish territorial claim on Slovakia in 1938. After November 1938, many factories, power plants, millions of inhabitants, and even whole regions of Czechoslovakia remained in a territory that Hungary, Germany, or Poland occupied. The paper focuses on losses in three key areas: population, territory, and industry. This research is primarily based on the study of contemporary statistical reports in combination with archive materials that are placed in the National Archive in Prague and in the Slovak National Archive in Bratislava. In conclusion, it can be stated that the change of borders in 1938 had a negative impact on Slovakia and on the whole state. A new border meant a radical intervention in the republic’s economy, ethnic composition, and territorial integrity. As a result, the republic lost around 30 % of its territory, on which approximately a third of the population lived.
