The beginning of the propagation of dance and accompanying music called polka is generally attributed to a young woman, Anna Slezáková (born Anna Chadimová). The music teacher Josef Neruda noticed her dancing in an unusual way to accompany a local folk song called "Strýček Nimra koupil šimla", or "Uncle Nimra Bought a White Horse", in 1830. She is said to have called the dance "Maděra" because of its liveliness. The dance was further propagated by Neruda, who put the tune to paper and taught other young men to dance it. Čeněk Zíbrt notices that a common claim that the events happened in Týnec nad Labem, Bohemia, in 1834 is incorrect. Zibrt writes that when he published this traditional story in 1894 in "Narodni Listy" newspaper, he received a good deal of feedback from eyewitnesses. In particular, he wrote that according to further witness, the originating event actually happened in 1830, in Kostelec nad Labem, where she worked as a housemaid. Zíbrt writes that he published the first version of the story (with incorrect place name) in "Bohemia" (June 5, 1844), from where it was reprinted all over Europe and in the United States. Zíbrt also wrote that simple Czech folk said they knew and danced polka long before the nobles got hold of it, i.e., it is a truly folk Czech dance.
