In both relative and absolute terms, the bodycount of the last century was the highest in recorded history. There were 16 conflicts that left more than a million dead, another 6 that claimed from a half million to a million lives, and 14 more that claimed from a quarter to a half million lives; all told, about 167 to 188 million people lost their lives as a result of armed conflict. Harvard historian Niall Fergusson has written a monumental tour-de-force attempting to answer the question: why?
Being Niall Ferguson, author of "Empire" and "Colossus," the reasons are not the conventional ones. Large-scale killing has taken place in previous centuries, and the 20th century, blessed with material progress, should have been a peaceful one, yet the bloodshed was unprecedented.
Ferguson disagrees with the traditional explanation that the scale of killing was a result of more sophisticated military hardware. The killing fields of Rwanda and Cambodia showed that large-scale massacres could be carried out by primitive weapons.
Stalinism, Fascism, and Anti-Semitism have been cited as the sources of the centuries largests mass murders. Ferguson argues that although the nation-states that formed after the disintegration of empires embraced extreme ideologies, these nation-states were not inherently evil; in fact they carried out many positive and peaceful goals.
Ferguson, instead, identifies three elements - the three E's - that were responsible for much of the 20th century's armed conflicts: "ethnic disintegration, economic volitility, and empires in decline." One of the primary examples he uses to illustrate his thesis is the case of Central and Eastern Europe. Prior to World War I, four empires were on the brink of dissolution - the Hohenzollerns of Prussia, the Hapsburgs of Austro-Hungary, the Romanovs of Russia, and the Ottomans in Turkey. The co-existence of these multi-ethnic populations was always tenuous at best, the transformation from empire to nation-state was anything but smooth. The nation-states that emerged after the war - Turkey, Germany, and Russia had their own agendas to cope with the worldwide economic depression that followed the war. The other countries that were located in between from the Baltic to the Balkans experienced some of the bloodiest ethnic cleanings in history. And this was only a foreboding of what was to come.
What makes this "fatal formula" so pertinent today is that all of these elements exist in the Middle East today. According the Ferguson, as he elegantly argued in "Colossus," America is an empire, a liberal empire, but it is also an empire in denial. With economic instablity, which already existed before the invasion of Iraq; ethnic strife between Sunni and Shia; and America's wavering support for the young nation: everything seems to be heading toward full-scale civil war. Making matters worse, the conflict will inevitably spill over into Iran, Turkey, Syria, Jordan, and Saudi Arabia, all of whom have ethnic and religious interests in the outcome.
Ferguson's analysis seems to be convincing. The brutality that we are witnessing today in Iraq where Sunni and Shia treat each other as "inferior or malignant species" is remarkably reminiscent of some of the 20th century's worst nightmares. We can only hope that the bloodletting can be stopped and that a political solution can be found. Unfortunately, the ranks of the optimists are dwindling.
