At the time of Władysław's reign many Germans lived in Polish towns. They opposed him and rioted against him. After the riot of Lord Mayor Albert Władysław ordered his soldiers to expel all Germans from the town. One of them asked Władysław, how to recognise a German. The duke ordered them to make everyone speak aloud the words "Soczewica, koło, miele, młyn" (that means "Lentil, wheel, grinds, mill"). A man who could not speak it correctly was regarded as a German.
