Late Bronze Age Collapse, Mycenaean Civilization Collapse — Collapse As Witnessed 3400-3000 Years Ago

February 11, 2015 in Humans

The Late Bronze Age Collapse, often alternately referred to as the Mycenaean Palatial Civilization Collapse, was a period of time — roughly between the years of 1250-1000 BC (3250-3000 years ago) — that was violent, and catastrophically disruptive with regard to cultures, social systems/practices, government institutions, languages, ethnic identities, trade routes, literacy, and technologies.

During these years, all of the large urban centers and governing systems of the Mediterranean, the Aegean, and most of Southwestern Asia, collapsed — leaving behind, after a period of turmoil and mass migration, the isolated village cultures of the Greek Dark Ages.

This period of time saw the end of the various Mycenaean kingdoms of the Mediterranean, the Hittite Empire in Anatolia and Syria, and the New Kingdom of Egypt in Syria and Canaan.

Desertification is a process of land-degradation by which a region becomes progressively drier and drier — eventually becoming desert. Or, to put it another way — desertification is the process by which previously biologically productive land is transformed into wasteland.

There’s actually currently something of a debate over the use of the term though. As it stands, the most widely accepted definition is probably the one that’s now printed in the Princeton University Dictionary — which defines it this way: “The process of fertile land transforming into desert typically as a result of deforestation, drought, or improper/inappropriate agriculture”

Desertification

There are a number of different causes/mechanisms behind the process, such as deflation (the loss of stabilizing vegetation, and of top soil); erosion; and soil-salinity-rise (via irrigation mostly). Read the rest of this entry →
