The Hittite sack of Babylon around 1595 ended the Old Babylonian Kingdom and left a political power vacuum in the region. It was not until the arrival of the Kassites from the Eurasian steppe lands that the kingdom became politically stable. ‘The Kassites’ outlines how, despite few written and archaeological sources, the Kassites took control of the region and bestowed the greatest benefit on Babylonia in the form of nationhood. Their respect for the traditions and customs of their subjects provided a peaceful, secure environment within the land, which helped ensure that the arts and sciences flourished, in such fields as literature, medicine, mathematics, astronomy, music, art, and architecture.
