The initial location of Dayenu according Bryce. It was definitely more southern in 12th century BC Assyrian records. It could be also slightly more western initially. Dayenu was the most prominent kingdom in Nairi tribal federation. It's king Seni was the leader of the anti-Assyrian Nairian coalition. He was captured after the defeat. It seems after those events Dayenu moved further north were they are attested in Urartian period as Diaukhi.
