Tell Sheikh Hamad

Tell Sheikh Hamad (تل الشيخ حمد), also Dur-Katlimmu, is an archeological site in eastern Syria on the lower Khabur River, a tributary of the Euphrates.

Chalcolithic Period
The site of Tell Sheikh Hamad was occupied from the Late Chalcolithic period (Late Neolithic, M4), when it was a small settlement.

Mitanni Period
In the Late Bronze Age, the region surrounding Dur-Katlimmu was part of the Mitanni Empire and the kingdom of Hanigalbat. Following the fall of the stronghold Carchemish to Suppiluliuma of the Hittites, and the assassination of great king Tushratta in 1345 BC, the Mitanni Empire struggled with civil war and outside pressure until it fell. A quantity of Hittite potter was found at the site.

During the reign of Shalmaneser
The city was established as the capital of a new Assyrian province by Shalmaneser I (r. 1263-34 B.C.) following the collapse of the Mitanni Empire. He put Ibašši-ilī son of Adad-nirari I, his brother, as the founder of the dynasty on the royal throne. Dur-Katlimmu (Tell Seh Hamad) became the capital of this kingdom on the lower Habur river. The ruler bore the title 'grand vizier' (sakallu rabi'u) and 'king of the land of Hanigalbat' (sar mat Hanigalbat).

End of the Assyrian Empire
During the fall of the Assyrian Empire (911-605 BC), sections of the Assyrian army retreated to the western corner of Assyria after the fall of Nineveh, Harran and Carchemish, and a number of Assyrian imperial records survive between 604 BC and 599 BC in and around Dur-Katlimmu, and so it is possible that remnants of the Assyrian administration and army still continued to hold out in the region for a few years.

After the fall of the Assyrian Empire
After the fall of the Assyrian Empire, Dur-Katlimmu became one of the many Near- and Middle-Eastern cities called Magdalu/Magdala/Migdal/Makdala/Majdal, all of which are simply Semitic language toponyms meaning "fortified elevation, tower".

Excavations
In 1878 Hormuzd Rassam dug some test trenches and removed a stele fragment. The site was excavated between 1978 and 2010, led by Hartmut Kühne.

Excavations have recovered 550 cuneiform Akkadian and 40 Aramaic texts belonging to a senior guard of Ashurbanipal.

In July 2020, French archaeologists excavated Tell Sheikh Hamad during the Syrian Civil War, according to the Anadolu Agency.
