Archaeological Bonanza: Ancient City Emerges From the Tigris River

Drought Reveals 3400-Year-Old Urban Center of the Mitanni Empire

The Kingdom of Mitanni, also known as Hurri to the Hittites, Hanigalbat or Hani-Rabbat to the Assyrians, and Maryannu, Nahrin or Mitanni to Egyptians, was a powerful nation around the 16th century BC that stretched over portions of present-day Syria, Iraq, and Turkey.

Although it was believed to be a substantial regional power for a time, not a lot is known about it today compared to other ancient nations of the time. Part of the reason is that no native sources for the history of Mitanni have been discovered yet. 

Now, a team of German and Kurdish archaeologists has uncovered a 3400-year-old Mitanni Empire-era city once located on the Tigris River. The settlement emerged from the waters of the Mosul reservoir early this year as water levels fell rapidly due to extreme drought in Iraq. The extensive city with a palace and several large buildings could be ancient Zakhiku – believed to have been an important center in the Mitanni Empire (ca. 1550-1350 BC).

Bronze Age City Resurfaced Due to Drought

Iraq is one of the countries in the world most affected by climate change. The south of the country in particular has been suffering from extreme drought for months. To prevent crops from drying out, large amounts of water have been drawn down from the Mosul reservoir – Iraq’s most important water storage – since December. This led to the reappearance of a Bronze Age city that had been submerged decades ago without any prior archaeological investigations. It is located at Kemune in the Kurdistan Region of Iraq.

This unforeseen event put archaeologists under sudden pressure to excavate and document at least parts of this large, important city as quickly as possible before it was resubmerged. The Kurdish archaeologist Dr. Hasan Ahmed Qasim, chairman of the Kurdistan Archaeology Organization, and the German archaeologists Jun.-Prof. Dr. Ivana Puljiz, University of Freiburg, and Prof. Dr. Peter Pfälzner, University of Tübingen, spontaneously decided to undertake joint rescue excavations at Kemune. These took place in January and February 2022 in collaboration with the Directorate of Antiquities and Heritage in Duhok (Kurdistan Region of Iraq).

Fritz Thyssen Foundation Supported Excavations

A team for the rescue excavations was put together within days. Funding for the work was obtained at short notice from the Fritz Thyssen Foundation through the University of Freiburg. The German-Kurdish archaeological team was under immense time pressure because it was not clear when the water in the reservoir would rise again.

Massive Fortification, Multi-Story Storage Building, Industrial Complex

Within a short time, the researchers succeeded in largely mapping the city. In addition to a palace, which had already been documented during a short campaign in 2018, several other large buildings were uncovered – a massive fortification with walls and towers, a monumental, multi-story storage building, and an industrial complex. The extensive urban complex dates to the time of the Empire of Mitanni (approx. 1550-1350 BC), which controlled large parts of northern Mesopotamia and Syria.

“The huge magazine building is of particular importance because enormous quantities of goods must have been stored in it, probably brought from all over the region,” says Puljiz. Qasim concludes, “The excavation results show that the site was an important center in the Mitanni Empire.”

The research team was stunned by the well-preserved state of the walls – sometimes to a height of several meters – despite the fact that the walls are made of sun-dried mud bricks and were under water for more than 40 years. This good preservation is due to the fact that the city was destroyed in an earthquake around 1350 BC, during which the collapsing upper parts of the walls buried the buildings.

Ceramic Vessels With Over 100 Cuneiform Tablets

Of particular interest is the discovery of five ceramic vessels that contained an archive of over 100 cuneiform tablets. They date to the Middle Assyrian period, shortly after the earthquake disaster struck the city. Some clay tablets, which may be letters, are even still in their clay envelopes. The researchers hope this discovery will provide important information about the end of the Mitanni-period city and the beginning of Assyrian rule in the region. “It is close to a miracle that cuneiform tablets made of unfired clay survived so many decades underwater,” Pfälzner says.

Conservation Project To Prevent Damage by Rising Water

To avert further damage to the important site by the rising water, the excavated buildings were completely covered with tight-fitting plastic sheeting and covered with gravel fill as part of an extensive conservation project funded by the Gerda Henkel Foundation. This is intended to protect the walls of unbaked clay and any other finds still hidden in the ruins during times of flooding. The site is now once more completely submerged.
