QUOTE : none of these individual factors would have been cataclysmic enough on their own to bring down even one of these civilizations, let alone all of them. However, they could have combined to produce a scenario in which the repercussions of each factor were magnified, in what some scholars have called a “multiplier effect.”95 The failure of one part of the system might also have had a domino effect, leading to failures elsewhere. The ensuing “systems collapse” could have led to the disintegration of one society after another, in part because of the fragmentation of the global economy and the breakdown of the interconnections upon which each civilization was dependent. In 1987, Mario Liverani, of the University of Rome, laid the blame upon the concentration of power and control in the palaces, so that when they collapsed, the extent of the disaster was magnified. As he wrote, “the particular concentration in the Palace of all the elements of organization, transformation, exchange, etc.—a concentration which seems to reach its maximum in the Late Bronze Age—has the effect of transforming the physical collapse of the Palace into a general disaster for the entire kingdom.
