Especially Ján Kollár and Pavel Jozef Šafárik were adherents of Pan-Slavic concepts that stressed the unity of all Slavic peoples. They considered Czechs and Slovaks members of a single nation and they attempted to draw the languages closer together. In the 1840s, the Protestants split as Ľudovít Štúr developed a standard language based on the dialect from central Slovakia. His followers stressed the separate identity of the Slovak nation and uniqueness of its language. Štúr's version was finally approved by both the Catholics and the Lutherans in 1847 and, after several reforms, it remains standard Slovak.
