A symbol of the rising tensions was the fate of Charles University, then called Charles-Ferdinand University. Its Czech students had become increasingly perturbed by the sole use of German for instruction. During the 1848 revolution, both Germans and Czechs fought to make Czech one of the university's official languages. They achieved that right, and the university became bilingual. By 1863, out of 187 lecture courses, 22 were held in Czech, the remainder being in German. In 1864, some Germans suggested the creation of a separate Czech university. Czech professors rejected that because they did not wish to lose the continuity of university traditions.
