  The Mesopotamian Bronze Age began about 3500 BC and ended with the Kassite period (c. 1500 BC – c. 1155 BC). The usual tripartite division into an Early, Middle and Late Bronze Age is not used in the context of Mesopotamia. Instead, a division primarily based on art and historical characteristics is more common.
  
  The cities of the Ancient Near East housed several tens of thousands of people. Ur, Kish, Isin, Larsa, and Nippur in the Middle Bronze Age and Babylon, Calah, and Assur in the Late Bronze Age similarly had large populations. The Akkadian Empire (2335–2154 BC) became the dominant power in the region. After its fall, the Sumerians enjoyed a renaissance with the Neo-Sumerian Empire. Assyria, along with the Old Assyrian Empire (c. 1800–1600 BC), became a regional power under the Amorite king Shamshi-Adad I. The earliest mention of Babylon (then a small administrative town) appears on a tablet from the reign of Sargon of Akkad in the 23rd century BC. The Amorite dynasty established the city-state of Babylon in the 19th century BC. Over 100 years later, it briefly took over the other city-states and formed the short-lived First Babylonian Empire during what is also called the Old Babylonian Period.
  
  Akkad, Assyria, and Babylonia all used the written East Semitic Akkadian language for official use and as a spoken language. By that time, the Sumerian language was no longer spoken, but was still in religious use in Assyria and Babylonia, and would remain so until the 1st century AD. The Akkadian and Sumerian traditions played a major role in later Assyrian and Babylonian culture. Despite this, Babylonia, unlike the more militarily powerful Assyria, was founded by non-native Amorites and often ruled by other non-indigenous peoples such as the Kassites, Aramaeans and Chaldeans, as well as by its Assyrian neighbours.
