The Black Death

     The Black Death (plague) serves as a convenient divider between the central and the late Middle Ages.  Changes begin to take place - the growth of cities and there importance, economic and demographic crises, political dislocation and realignment, and powerful new currents in culture and religion.   The later Middle Ages are usually characterized as a period of crisis and trouble.
     The Black Death did not cause the crisis, evidence shows that it began well before 1347, but the plague exacerbated problems and added new ones, and the tone of crisis is graver in the second half than in the first half of the century.  History of Western Civilization - The Black Death
     If the plague has been eradicated from the 14th Century, how can it affect the world today?  Is anything truly eradicated, or is it "in hiding," waiting to be awakened to attack again?  Discuss this issue and bring in details as to why/why not you believe the plague is eradicated or whether anything is truly eradicated.
