1911-12 Austrian football championship
For the 1911/12 season, the NÖFV (Lower Austrian Football Association) announced a championship with compulsory match dates for Viennese clubs for the first time. This championship is officially considered the first Austrian football championship. Because the Austria-Hungary Empire  existed then there was a second equal Austrian championship in Moravia-Silesia. In Hungary, a championship was organized by the Hungarian Football Association for the seventh time. From today's perspective if you refere to the Austrian championship of 1912 you mean first class of the NöFV.
