Ancient Greece: an easy and complete summary of the history and civilization of ancient Greece, the cradle of western civilization. Ancient Greece - the origins In the eleventh century B.C., after the collapse of the Mycenaean civilization, Greece entered a phase of economic and cultural decline, evidenced by demographic contraction and the abandonment of writing. For this reason, historians have defined the period between the 11th and 9th centuries B.C. as "dark centuries" or "Hellenic Middle Ages". Between the 11th and 10th centuries B.C. the first Greek colonization took place: the Dorians, an original people from Macedonia and Illyria, pushed groups of Aeolians and Ions to the western coasts of Asia Minor (today Turkey). These gave rise to a long series of cities, such as Miletus, Ephesus and Halicarnassus; the practice of writing again spread, through a new alphabet derived from the Phoenician alphabet, and the Greek cities gave themselves the first written laws.
