The story of the Slovak inter-war historiography cannot be conceptualized without reconstruction of the relationship between its founders. The most important among them were Václav Chaloupecký, the first Czech professor of Czechoslovak history at the Comenius University, and his successor – after Chaloupecký's forced departure from Slovakia in late 1938 – the first professional Slovak archivist and historian professor Daniel Rapant. The inter-war era of the Slovak historiography cannot be fully understood without putting Chaloupecký and Rapant in comparison.
