WHS Destroyed during the 'Bronze Age Collapse'. The term “Late Bronze Age Collapse” refers to the period around 1200 - 1100BC when a significant change occurred in the nature of the civilizations occupying the lands of, and adjacent, to the Eastern Mediterranean. This was accompanied by destruction of the cities of those civilizations, the demise of their Kingdoms and a transition period, after which different and, at first smaller, entities emerged. The causes of these events have been assigned variously to technological advances, natural catastrophe and migrations. Whilst the empires of Egypt and Babylon were significantly impacted they managed to survive and the changes were greatest in the Eastern Mediterranean. In Greece the events were followed by the “Greek Dark Ages” and are thought to have influenced the story lines of later Greek epic poems such as the Iliad and the Odyssey capturing both the past glories and the chaos of the period.
