The history of slavistics is generally divided onto three periods. Until 1876 the early slavists concentrated on documentation and printing of monuments of slavic languages, among them the first texts written in national languages. It was also then that the majority of Slavic languages received their first modern Dictionaries , grammars and compendia. The second period, ending with World War I , was marked by fast development of Slavic Philology and Linguistics , most notably in the circle formed around August Schleicher and August Leskien at the University Of Leipzig . After World War I slavic scholars focused on Dialectology , while the science developed in countries with populations of Slavic origins. After the World War II centres of Slavic studies were also formed in various universities outside of such states.
