One of the most powerful volcanic events of the past 10,000 years occurred on the Greek island of Thera (Santorini) in the Aegean Sea, yet researchers have long debated whether it took place in the late 17th or 16th century BCE. Ash from the eruption spread across much of the eastern Mediterranean, prompting archaeologists to question how this dramatic event aligned with ancient Egyptian chronology. A research team from Ben-Gurion University of the Negev and the University of Groningen has now provided the first radiocarbon dates related to King Ahmose, the ruler known for reunifying Upper and Lower Egypt and founding the New Kingdom. Their results suggest that the Santorini eruption happened before the New Kingdom, placing it in the Second Intermediate Period. These new measurements strongly support a "low" (i.e. younger) timeline for the start of the 18th Dynasty, a shift that reshapes our understanding of Egypt’s interactions with nearby cultures.

Their findings were published in PLOS One.

New Radiocarbon Sampling From Key Egyptian Artifacts

Prof. Hendrik J. Bruins of the Jacob Blaustein Institutes for Desert Research at BGU's Sylan Adams Sde Boker Campus and Prof. Johannes van der Plicht of the University of Groningen received exceptional access to select artifacts from the British Museum and the Petrie Museum in London. Under the supervision of museum teams, they collected samples from several objects for radiocarbon dating. These included a mudbrick from the Ahmose Temple at Abydos (British Museum), a linen burial cloth linked to Satdjehuty (British Museum), and six wooden stick shabtis from Thebes (Petrie Museum).

Revised Timeline for the Santorini Eruption and Early Dynasties

Analysis of the samples showed that the massive eruption did not take place during the Egyptian New Kingdom, as some earlier interpretations suggested. Instead, it occurred earlier in the Second Intermediate Period. The radiocarbon ages for the Santorini event were markedly older than the first radiocarbon dates obtained for artifacts associated with Pharaoh Ahmose and those from the 17^th to early 18^th Dynasty.

"Our findings indicate that the Second Intermediate Period lasted considerably longer than traditional assessments, and the New Kingdom started later," says Prof. Hendrik J. Bruins.
