Kingdom of Hungary Máté Csák III. The kingdom of Hungary reached an age of prosperity and stability under Charles I. The gold mines of the Kingdom were extensively worked and soon Hungary reached a prominent standing in European gold production. The forint was introduced as a currency, replacing the "denars", and soon after Charles's reforms were implemented, the economy of the Kingdom started to prosper again, having fallen into a parlous state following the Mongol invasion. Charles exalted the cult to Saint Ladislaus I, using him as a symbol of bravery, justice and purity. He also venerated his uncle, Saint Louis of Toulouse.
European Currency Unit (U+20A0), comprises an interlaced C and E, which are the initial letters of the phrase 'European Community' in many European languages. However, this symbol was not widely used: few systems at the time could render it and in any case banks preferred (as with all currencies) to use the ISO code XEU. As the ECU was only an electronic unit of account and not a full currency, it did not have any official coins or notes that could be used for everyday transactions. However, various European countries and organisations like the European Parliament made commemorative and mock-up coins and notes.
