During period Q, Tell Brak was an important trade city in the Mitanni state. A two-story palace was built c. 1500 BC in the northern section of the tell, in addition to an associated temple. However, the rest of the tell was not occupied, and a lower town extended to the north but is now all but destroyed through modern agriculture. Two Mitannian legal documents, bearing the names of kings Artashumara and Tushratta, were recovered from the city, which was destroyed between c.1300 and 1275 BC, in two waves, first at the hands of the Assyrian king Adad-Nirari I, then by his successor Shalmaneser I.
