Late Bronze Age collapse
The Phrygians (gr. Φρύγες, "Phrúges" or "Phrýges") were an ancient Indo-European people, who established their kingdom with a capital eventually at Gordium. It is presently unknown whether the Phrygians were actively involved in the collapse of the Hittite capital Hattusa or whether they simply moved into the vacuum left by the collapse of Hittite hegemony after the Late Bronze Age collapse.
