Interactions with the Mesopotamian south grew during the second half of period F (designated "LC4") c. 3600 BC, and an Urukean colony was established in the city. With the end of Uruk culture c 3000 BC, Tell Brak's Urukean colony was abandoned and deliberately leveled by its occupants. Tell Brak contracted during the following periods H and J, and became limited to the mound. Evidence exists for an interaction with the Mesopotamian south during period H, represented by the existence of materials similar to the ones produced during the southern Jemdet Nasr period. The city remained a small settlement during the Ninevite 5 period, with a small temple and associated sealing activities.
