Marduk-apla-iddina I, contemporarily written in cuneiform as 𒀭𒀫𒌓𒌉𒍑𒋧𒈾 dAMAR.UTU-IBILA-SUM-na and meaning in Akkadian: "Marduk has given an heir", was the 34th Kassite king of Babylon c. 1171–1159 BC. He was the son and successor of Meli-Shipak II, from whom he had previously received lands, as recorded on a kudurru, and he reigned for 13 years. His reign is contemporary with the Late Bronze Age collapse. He is sometime referred to as Merodach-Baladan I.

Dur-Kurigalzu was a city in southern Mesopotamia, near the confluence of the Tigris and Diyala rivers, about 30 kilometres (19 mi) west of the center of Baghdad. It was founded by a Kassite king of Babylon, Kurigalzu I and was abandoned after the fall of the Kassite dynasty. The city was of such importance that it appeared on toponym lists in the funerary temple of the Egyptian pharaoh, Amenophis III at Kom el-Hettan". The prefix Dur is an Akkadian term meaning "fortress of", while the Kassite royal name Kurigalzu is believed to have meant "shepherd of the Kassites". The tradition of naming new towns Dur dates back to the Old Babylonian period with an example being Dūr-Ammī-ditāna. The city contained a ziggurat and temples dedicated to Mesopotamian gods, as well as a royal palace which covered 420,000 square meters.
