Behind the massacre in 1298 was also the desire to combine the northern and southern parts of the city, which were divided by the Pegnitz river. The Jews of the German lands suffered many massacres during the plague years. In 1349 Nuremberg's Jews were subjected to a pogrom. The plague was also present in 1405, 1435, 1437, 1482, 1494, 1520 and 1534.

Frequent fights took place with the burgraves without, however, inflicting lasting damage upon the city. After the castle had been destroyed by fire in 1420 during a feud between Frederick IV (since 1417 margrave of
