Sumer was an ancient region and civilization in southern Mesopotamia, in what is now southern Iraq, between the Tigris and Euphrates rivers. It is widely regarded as the site of the earliest known civilization and is associated with early urban life, cuneiform writing, and city-states such as Uruk, Ur, and Eridu.

Geography and setting

Sumer occupied the southernmost part of Mesopotamia between the Tigris and Euphrates rivers. Its riverine environment supported agriculture, settlement growth, and the development of major urban centres.

History and development

The region was settled in the late Neolithic period and developed into one of the world’s earliest urban civilizations. Sumer’s history is usually placed between the fifth and third millennia BCE, with later dominance shifting to Akkadian- and Babylonian-led states.

Language and writing

The Sumerian language is one of the earliest recorded languages and is classified as a language isolate. Sumerian scribes used cuneiform, one of the world’s earliest writing systems, for administrative and literary purposes.

Culture and achievements

Sumerian society produced city-states, temple complexes, irrigation systems, and early bureaucratic institutions. It is also associated with foundational works of Mesopotamian literature, including traditions linked to the Epic of Gilgamesh.

Key facts

  • Sumer was located in southern Mesopotamia, in the area later known as Babylonia and now part of Iraq.
