If the Golden Bull be excepted, the true interest of this reign is in the movements beyond the range of the emperor's influence. It is significant that at this time the _Femgerichte_, or Fehmic Courts (q.v.), vastly extended the sphere of their activities, and that in the absence of a strong central authority they were respected as a check upon the lawlessness of the princes. The cities, notwithstanding every kind of discouragement, formed new associations for mutual defence or strengthened those which already existed. The Hanseatic League carried on war with Valdemar V., king of Denmark, and his ally, the king of Norway, seventy-seven towns declaring war on these monarchs in 1367, and emerged victorious from the struggle, while its commerce extended to nearly all parts of the known world. In 1376 some Swabian towns formed a league which, in spite of the imperial prohibition, soon became powerful in south-west Germany and defeated the forces of the count of Württemberg at Reutlingen in May 1377. The emperor, meanwhile, was occupied in numerous intrigues to strengthen his personal position and to increase the power of his house. In these he was very fortunate, managing far more than his predecessors to avoid conflicts with the Papacy and the princes. The result was that when he died in November 1378 he wore the crowns of the Empire, of Germany, of Bohemia, of Lombardy and of Burgundy; he had added Lower Lusatia and parts of Silesia to Bohemia; he had secured the mark of Brandenburg for his son Wenceslaus in 1373; and he had bought part of the Upper Palatinate and territories in all parts of Germany.
