Slovak humanist Ján Kollár and Andrej Ľudovít Radlinský attempted to standardize a new literal language called Old Slovak (staroslovenčina), a version of Slovakized Czech. According to the contemporary Pan-Slavic views, the Slavic nation consisted of four tribes, the Czechoslovak, the Polish, the Russian and the Illyrian (Southern Slavs). Kollár assumed a common origin of Czechs and Slovaks. The original language, he claimed, is closer to Slovak, with Czech allegedly losing its beauty due to contact with the German language. After the suppressing of the Hungarian Revolution of 1848, Kollár got an approval of the government in Vienna to use "Old Slovak" as an administrative and educational language. The trial to create a common literal language for Czechs and Slovaks failed. Czechs had difficulties understanding Kollár's "improvements" of Czech by Slovakisms, and the younger Slovak generation preferred standardization of Slovak.
