Civilisation Collapse has occurred many times over past millennia in all parts of the world. The American anthropologist, Joseph A. Tainter defines collapse as “a rapid shift to a lower level of complexity(a) .” Societal disintegration immediately brings to mind the Maya, the Indus Valley and in what are relatively more modern times, the Western Roman Empire.
The causes are usually a combination of factors, such as, climate change, warfare, disease or excessive expansionism. Global catastrophes such as encounters with comets or asteroids are rare, while more local events such as earthquakes, volcanic eruptions or tsunamis can also be thrown into the mix. These have all been encountered from time to time, but have rarely been blamed for the collapse of a society; recovery from such limited regional events is usually possible.
The Mediterranean has seen its share of all these catastrophic events. A major tsunami on Sardinia, volcanic eruptions in Italy, earthquakes in North Africa and the Eastern Mediterranean. Close encounters with extraterrestrial bodies have also been proposed in that region.
Perhaps the best documented civilisation collapse is that which occurred around 1200 BC and affected many societies, particularly in the Middle East(b) . Israel Finkelstein, a leading Israeli archaeologist, has attributed this event to climate change and is of the view that this disruption was global in extent.
Inevitably, Atlantis has been cited as an example of civilisation collapse, particularly supporters of the Minoan Hypothesis, who link the 2nd millennium BC eruptions of Thera with the demise of the Minoans on Crete. Also popular is the idea that Atlantis had been a large island in the Atlantic Ocean destroyed by a cometary impact or the rising sea levels as the glaciers melted at the end of the last Ice Age.
A variety of other theories have associated Atlantis with the collapse of a civilisation. For example, Frank Joseph claims that 40,000 years ago “sudden sea-level rises triggers migration from Mu around. The Pacific motherlanders settle on a large, fertile island about 380 kilometers due west from the Straits of Gibraltar. There, the newcomers merge with the native Cro-Magnon inhabitants, resulting in a new, hybrid culture – Atlantis.”
