In the absence of documents and objects that can be precisely dated, events at Mycenae can only be dated relatively within the constraints of Helladic chronology which relies on categorisation of stratified material objects, mainly pottery, within an agreed historical framework. Mycenae developed into a major power during LHI (c. 1550 – c. 1450 BC) and is believed to have become the main centre of Aegean civilisation through the fifteenth century to the extent that the two hundred years from c. 1400 BC to c. 1200 BC (encompassing LHIIIA and LHIIIB) are known as the Mycenaean Age. The Minoan hegemony was ended c. 1450 and there is evidence that Knossos was occupied by Mycenaeans until it too was destroyed c. 1370 BC. From then on, Mycenaean expansion throughout the Aegean was unhindered until the massive disruption of society in the first half of the twelfth century (LHIIIC) which ended Mycenaean civilisation and culminated in the destruction of Mycenae itself c. 1150 BC.
