During the reign of John of Luxembourg's son Charles IV, the Czech lands experienced the Golden Age of their history. Charles IV was a highly educated man (he spoke five languages), an excellent diplomat and a very good king. He established Prague as the cultural capital of central Europe and made it one of the most prosperous European cities at the time. The Czech language was promoted to the official language in the country along with Latin and German, and the position of Bohemia became very strong.
Charles IV loved Prague and the city flourished during his rule. The Prague bishopric was upgraded to an archbishopric and when the king was crowned the Holy Roman Emperor in 1355, Prague's status increased to the capital of the Holy Roman Empire. Many building projects were started during Charles' reign, including the St. Vitus Cathedral. In 1348, Prague's New Town (Nové město) was founded, the Charles University was established to become the first university in Central Europe, and the Karlštejn castle was founded to protect the imperial jewels and other treasures. The construction of Charles Bridge began in 1357 at the place where Judith Bridge once stood (it collapsed in a flood in 1342).
Charles IV is remembered as the most beloved Czech king and the "father of the Czech nation". Charles IV's son and successor Wenceslas IV took the throne after his father and his reign extended into the time of the Hussite wars of the 15th century.</small></i>
