During the battles with the Mongols Wrocław Castle was successfully defended by Henry II the Pious. Reconstruction after the Mongol invasion of 1241 by the city's founder Heinrich Before Breslau was founded under the name Vratislavia after the Mongol invasion of 1241, there was already a German community, that, according to Pusch "probably comprised German merchants which was so strong at the beginning of the 13th century, that the Piast Duke Henry the Bearded thought it wise to appoint a German mayor."
