The aim of paper is to give evidence of the link between the reforms of coins, weihgts and measures provided in the Czech and Austrian lands by Premysl II Ottokar, King of Bohemia (1253-1278) and Duke of Austria (1251-1276), and legal and administrative reforms realized in the mint of Venice (Zecca) and in the house of German merchants (Fondaco dei Tedeschi). The author gives these reforms to connection with the 13th century trade revolution.
