Nabopolassar fought with an Assyrian-style army and took the throne of Babylon. Thirteen years later, Nineveh fell despite Egyptian help. Babylon took over much of the Assyrian empire. Later he defeated the last Assyrian king at Harran. His success was seen as Marduk’s revenge. Captured wealth from Assyrian royal cities allowed major building work at Babylon, which was continued by Nabopolassar’s son Nebuchadnezzar II. Neither king left statues of themselves, and cylinder seals represent gods by their symbols. Major subsidence in the citadel required frequent rebuilding on the Southern Palace. The names of temples and gates were compiled on to a clay tablet as a literary work. Colour-glazed bricks adorned the Processional Way leading to the temple of the New Year festival outside the citadel walls. That festival is described. Some of his creations Nebuchadnezzar described as a Wonder, but he made no mention of the Hanging Garden. In a separate part of the citadel, Nebuchadnezzar built a Summer Palace. His conquests included Tyre and Ashkelon but not Egypt or Lydia. He sacked the Temple in Jerusalem and deported its royal family to Babylon. Other captives settled on land nearby. Business archives of long duration continue into the Achaemenid period.

The content and significance of Hammurabi’s law code stela, including material and artistic aspects as well as text, are described and related to earlier law codes from other cities and biblical parallels. Protection of property, trade, family, warfare, and personal injury are among the topics. The separate content of its prologue and epilogue are discussed. The system of scribal education that lay behind its composition, from primary school to tertiary, was based on a formal curriculum beginning with sign lists and word lists. Model contracts and model letters, and extracts from myths and epics are found alongside satire and humour. The importance of divination and oracles for military success is emphasized. Precursors to themes later found in the Epic of Creation, such as gods waging war against Chaos can already be found in contemporary literature. The rise of Marduk can be traced in relation to Hammurabi’s conquests. The downside of warfare is explored in the Poem of Agushaya. The Epic of Creation is of central importance for Marduk and Babylon as world leaders, superseding earlier claimants. Epics from southern Mesopotamia are earlier and do not feature Marduk or Babylon.

Darius I overcame rebellions and seized the throne of Babylon, but cuneiform scholarship continued and developed; religious practices did not change, nor did the great buildings on the citadel. The zodiac scheme came into use. The Achaemenid king took Babylonian royal titles and promoted the worship of Marduk for local purposes. Xerxes broke the continuity. Following an uprising, a purge led to the ending of many archives. The province of Babylon was divided in two. Subsequent Achaemenid kings continued to treat Babylon with reverence. Alexander the Great defeated Darius III, entered Babylon, retained the Persian satrap, and moved treasure from Susa and Ecbatana to Babylon. He was recognized as a god. Lack of sons at his premature death precipitated a civil war from which Alexander’s commander Seleucus emerged to take the throne jointly with his son Antiochus. The derelict ziggurat was demolished, but temples and rituals, chronicles and astronomical diaries, continued as before. Aramaic was widely used, and fewer texts were inscribed in cuneiform. Interest in the fall of Assyria and of the Babylonian empire is apparent in Greek literature. Famous scholars include Berossus and named astronomers. Parthians invaded and eventually ended the dynasty.
