Abstract
Like many other universities across Europe, the Czech Charles-Ferdinand University in Prague (later Charles University), too, since the end of the nineteenth century tried to reach wider strata of society using lectures intended for the broad public, so-called 'extensions'. These activities importantly included several representatives of historical Slavic studies, especially Jaroslav Bidlo and his student Milada Paulová.
This study focuses on the period during which Bidlo, in 1921-1931, served as president of the Prague committee for organising lectures for the broad public, the 'Extension of Prague Universities', while Paulová helped as a secretary of this institution (1921-1935).
