Washukanni Washukanni (or Waššukanni) was the capital of the Hurrian kingdom of Mitanni, from around 1500 BC to the 13th century BC. Its precise location is unknown. A proposal locates it under the largely unexcavated mound of Tell el Fakhariya, near Tell Halaf in Syria, but that is rejected by Edward Lipinski.
Tell Shemshara Tell Shemshara is an Assyrian archaeological site located along the Little Zab in Sulaymaniyah Governorate, northeastern Iraq. The site was excavated between 1957 and 1959 by Danish and Iraqi archaeologists and was inundated by Lake Dukan until recently. The excavations showed that the site was occupied, although not continuously, from the Hassuna period (early sixth millennium BCE) until the 14th century CE. A small archive recovered from the Middle Bronze Age layers (early second millennium BCE) revealed that, at least in that period, the site was called Shusharra and was the capital of a small, semi-independent polity called "māt Utêm" or "land of the gatekeeper" ruled by a man called Kuwari.
