Late Bronze Age collapse
Unlike other Mycenaean centers, such as Mycenae and Pylos, it is unclear whether Athens suffered destruction in about 1200 BC, an event traditionally attributed to a Dorian invasion (though now commonly attributed to a systems collapse, part of the Late Bronze Age collapse). The Athenians always maintained that they were 'pure' Ionians with no Dorian element. However, Athens, like many other Bronze Age settlements, went into economic decline for around 150 years following this.
