Judith of Thuringia. This bridge was destroyed by a flood in 1342, but some of the original foundation stones of that bridge remain in the river. It was rebuilt and named the Charles Bridge. In 1257, under King Ottokar II, Malá Strana ("Lesser Quarter") was founded in Prague on the site of an older village in what would become the Hradčany (Prague Castle) area. This was the district of the German people, who had the right to administer the law autonomously, pursuant to Magdeburg rights. The new district was on the bank opposite of the Staré Město ("Old Town"), which had borough status and was bordered by a line of walls and fortifications. Late Middle Ages Prague flourished during the 14th-century reign (1346–1378) of Charles IV, Holy Roman Emperor and the king of Bohemia of the new Luxembourg dynasty. As King of Bohemia and Holy Roman Emperor, he transformed Prague into an imperial capital and it was at that time by area the third-largest city in Europe (after Rome and Constantinople). Charles IV ordered the building of the New Town (Nové Město) adjacent to the Old Town and laid out the design himself. The Charles Bridge, replacing the Judith Bridge destroyed in the flood just prior to his reign, was erected to connect the east bank districts to the Malá Strana and castle area. In 1347, he founded Charles University, which remains the oldest university in Central Europe. He began construction of the Gothic Saint Vitus Cathedral, within the largest of the Prague Castle courtyards, on the site of the Romanesque rotunda there. Prague was elevated to an archbishopric in 1344, the year the cathedral was begun. The city had a mint and was a center of trade for German and Italian bankers and merchants. The social order, however, became more turbulent due to the rising power of the craftsmen's guilds (themselves often torn by internal conflicts), and the increasing number of poor. The Hunger Wall, a substantial fortification wall south of Malá Strana and the castle area, was built during a famine in the 1360s. The work is reputed to have been ordered by Charles IV as a means of providing employment and food to the workers and their families. Charles IV died in 1378. During the reign of his son, King Wenceslaus IV (1378–1419), a period of intense turmoil ensued. During Easter 1389, members of the Prague clergy
