During the Bronze Age, as described in the last chapter, the Minoans and Mycenaeans were two of the civilizations that were part of the international trade and diplomacy network of the Mediterranean and Middle East. The Minoans were a major seafaring civilization based on the island of Crete. They created huge palace complexes, magnificent artwork, and great wealth. They eventually vanished as a distinct culture, most likely after they were conquered and absorbed by the Mycenaeans, their neighbors to the north.
The Mycenaeans developed as a civilization after the Minoans were already established in Crete. The Mycenaeans lived on the Greek mainland and the islands of the Aegean Sea and were known primarily as sea-going merchants and raiders. They were extremely warlike, attacking each other, their neighbors, and the people they also traded with whenever the opportunity existed to loot and sack. The Mycenaeans were the protagonists of the famous epic poems written by the (possibly mythical) Homer, The Iliad and The Odyssey.
The Mycenaeans vanished as a civilization at the end of the Bronze Age. The cause was probably a combination of foreign invasions and local rebellions and wars. One strong possibility is that there was a sustained civil war among the Mycenaean palace-settlements that resulted in a fatal disruption to the economic setting that was essential to their very existence. A bad enough war in Greece itself could have easily undermined harvests, already near a subsistence level, and when they were destroyed by these conflicts, towns, fortresses and palaces could not be rebuilt. Whatever the cause, the decline of the Mycenaeans occurred around 1100 BCE, marking the beginning of what historians refer to as the Dark Age in Greek history.
Of all the regions and cultures affected by the collapse of the Bronze Age, Greece was among those hit hardest. First and foremost, foreign trade declined dramatically. Whereas the Mycenaeans had been seafaring traders, their descendants were largely limited to local production and trade. Agriculture reverted to subsistence levels, and trade with neighboring areas all but vanished. In turn, this reversion to local subsistence economies cut them off from important sources of nutrition and materials for daily life, as well as foreign ideas and cultural influences. The Greeks went from being a great traveling and trading culture to one largely isolated from its neighbors. The results were devastating: some scholarly estimates are that the population of Greece declined by as much as 90% in the centuries following the Bronze Age collapse.
