The reign of Shilhak-Inshushinak marked the high point of the Elamite kingdom and its military expansion in the 12^th century BCE. This foundation brick is evidence of the buildings commissioned by the king for his capital, Susa: "I, Shilhak-Inshushinak, son of Shutruk-Nakhunte, beloved servant of Inshushinak, king of Anzan and Susa, this place which ancient kings had built with baked bricks, I, Shilhak-Inshushinak, decorated it with glazed bricks; on them I inscribed my name." A few years later, Nebuchadnezzar I defeated the Elamites.

Brick conserved in the Louvre, Near East Antiquities, excavations by Jacques de Morgan, Sb 11945.
