Greek Dark Ages
The Greek Dark Age or Ages' (ca. 1200 BC–800 BC) are terms which have regularly been used to refer to the period of Greek history from the presumed Dorian invasion and end of the Mycenaean Palatial civilization around 1200 BC, to the first signs of the Greek city-states in the 9th century BC. These terms are gradually going out of use, since the former lack of archaeological evidence in a period that was mute in its lack of inscriptions (thus "dark") has been shown to be an accident of discovery rather than a fact of history.
From around 1200 BC, the palace centres and outlying settlements of the Mycenaeans' highly organized culture began to be abandoned or destroyed and by 1050 BC, the recognisable features of Mycenaean culture had disappeared. Many explanations attribute the fall of the Mycenaean civilization and the Bronze Age collapse to climatic or environmental catastrophe combined with an invasion by Dorians or by the Sea Peoples but no single explanation fits the available archaeological evidence.
Robert Drews describes the collapse as "the worst disaster in ancient history, even more calamitous than the collapse of the Western Roman Empire". A number of people have spoken of the cultural memories of the disaster as stories of a "lost golden age". Hesiod for example spoke of Ages of Gold, Silver and Bronze, separated from the modern harsh cruel world of the Age of Iron by the Age of Heroes.
The archaeological evidence shows a widespread collapse of Bronze Age civilization in the eastern Mediterranean world during the same period, as the great palaces and cities of the Mycenaeans were destroyed or abandoned. Around this time, the Hittite civilization suffered serious disruption and cities from Troy to Gaza were destroyed. Following the collapse, fewer and smaller settlements suggest famine and depopulation. In Greece the Linear B writing of the Greek language used by Mycenaean bureaucrats ceases. The decoration on Greek pottery after ca 1100 BC lacks the figurative decoration of Mycenaean ware and is restricted to simpler, generally geometric styles. It was previously thought that all contact was lost between foreign powers during this period, yielding little cultural progress or growth; however, artifacts from excavations at Lefkandi on the Lelantine Plain in Euboea show that significant cultural and trade links with the east, particularly the Levant coast, developed from c 900 BC onwards, and evidence has emerged of a migration of Hellenes to sub-Mycenaean Cyprus and the Syrian coast (at Al Mina).
