The Fall of the Kassite Dynasty and the Rise of the Second Dynasty of Isin

Following the collapse of the First Babylonian Dynasty under Hammurabi, the Babylonian Empire entered a period of relatively weakened rule under the Kassites for 576 years— the longest dynasty in Babylonian history. The Kassite Dynasty eventually fell due to the loss of territory and military weakness, which resulted in the evident reduction in literacy and culture. In 1157 BCE, Babylon was conquered by Shutruk-Nahhunte of Elam.

The Elamites did not remain in control of Babylonia long, and Marduk-kabit-ahheshu (1155-1139 BCE) established the Second Dynasty of Isin. This dynasty was the very first native Akkadian-speaking south Mesopotamian dynasty to rule Babylon, and was to remain in power for some 125 years. The new king successfully drove out the Elamites and prevented any possible Kassite revival. Later in his reign, he went to war with Assyria and had some initial success before suffering defeat at the hands of the Assyrian king Ashur-Dan I. He was succeeded by his son Itti-Marduk-balatu in 1138 BCE, who was followed a year later by Ninurta-nadin-shumi in 1137 BCE.

The Reign of Nebuchadnezzar I and His Sons

Nebuchadnezzar I (1124-1103 BCE) was the most famous ruler of the Second Dynasty of Isin. He not only fought and defeated the Elamites and drove them from Babylonian territory but invaded Elam itself, sacked the Elamite capital Susa, and recovered the sacred statue of Marduk that had been carried off from Babylon. In the later years of his reign, he devoted himself to peaceful building projects and securing Babylonia’s borders. His construction activities are memorialized in building inscriptions of the Ekituš-ḫegal-tila, the temple of Adad in Babylon, and on bricks from the temple of Enlil in Nippur. A late Babylonian inventory lists his donations of gold vessels in Ur. The earliest of three extant economic texts is dated to Nebuchadnezzar’s eighth year; in addition to two kudurrus and a stone memorial tablet, they form the only existing commercial records. These artifacts evidence the dynasty’s power as builders, craftsmen, and managers of the business of the empire.

Nebuchadnezzar was succeeded by his two sons, firstly Enlil-nadin-apli (1103-1100 BCE), who lost territory to Assyria, and then Marduk-nadin-ahhe (1098-1081 BCE), who also went to war with Assyria. Some initial success in these conflicts gave way to catastrophic defeat at the hands of Tiglath-pileser I, who annexed huge swathes of Babylonian territory, thereby further expanding the Assyrian Empire. Following this military defeat, a terrible famine gripped Babylon, which invited attacks from Semitic Aramean tribes from the west.

In 1072 BCE, King Marduk-shapik-zeri signed a peace treaty with Ashur-bel-kala of Assyria. His successor, Kadašman-Buriaš, however, did not maintain his predecessor’s peaceful intentions, and his actions prompted the Assyrian king to invade Babylonia and place his own man on the throne. Assyrian domination continued until c. 1050 BCE, with the two reigning Babylonian kings regarded as vassals of Assyria. Assyria descended into a period of civil war after 1050 BCE, which allowed Babylonia to once more largely free itself from the Assyrian yoke for a few decades.

However, Babylonia soon began to suffer repeated incursions from Semitic nomadic peoples migrating from the west, and large swathes of Babylonia were appropriated and occupied by these newly arrived Arameans, Chaldeans, and Suteans. Starting in 1026 and lasting till 911 BCE, Babylonia descended into a period of chaos.
