Bohemian historians believe that the polka was invented by a peasant girl (Anna Slezak, in Labska Tynice in 1834) one Sunday for her amusement. It was composed to a folk song "Strycek Nimra Koupil Simla (Uncle Nimra brought a white horse)." Anna called the step "Madera" because of its quickness and liveliness.
