Why this matters for Egyptian history
The Second Intermediate Period, dated roughly 1782–1550 BCE, has long been understood as a time of political fragmentation, military innovation and shifting power. It saw the introduction of new technologies such as the horse-drawn chariot, multiple competing capitals, and weakened central authority. If this period lasted longer than previously thought, historians must rethink how quickly Egypt recovered from collapse, how long the Hyksos ruled, and how the early New Kingdom developed its military and administrative strength. Just as importantly, the revised dating helps resolve a decades-old problem in Mediterranean archaeology: how Egyptian history lines up with Minoan, Levantine and Aegean chronologies. By placing the Thera eruption firmly before Ahmose’s reign, the study removes one of the most persistent points of chronological tension between Egypt and its neighbours.
