The paper is devoted to the status of the Hungarian minority’s teachers in Slovakia after the establishment of the Czechoslovak Republic (CSR) at the end of 1918. The CSR was a state including several ethnic minorities. Hungarians were the most numerous ethnic minorities in the Slovak parts. After the foundation of the CSR, the economic, political, social and ideological situation in the country changed radically. Some of the changes affected inhabitants of Slovakia only indirectly. Others interfered with their way of life to a significant degree. One of the areas which underwent a substantial change was education in all types of schools.
