Mycenaeans, who were based in mainland Greece, benefited from the collapse of the Minoan civilization and established themselves as a leading force throughout the Aegean during the last centuries of the 2nd millennium BC.
Major centres of the Mycenaean era are Mycenae, Pylos, Tiryns, Thebes, Iolcus. The Mycenaean civilization flourished for about four hundred years.
The Mycenaean cities were big and powerful, art and agriculture flourished and there was great prosperity. In this society the king was the one who had accumulated wealth.
The boom of this culture continued until the 12th century BC, when the power of the Mycenaean kingdoms gradually collapsed.
