In short
Around 2900 BCE, a catastrophic flood inundated the river valleys of ancient Mesopotamia, likely caused by the Tigris and Euphrates rivers overflowing during a particularly severe rainy season or surge event. The deluge devastated settlements across what is now Iraq, erasing cities and fundamentally reshaping how early civilizations understood divine punishment and human survival.
How it unfolded.
The five-minute version
What actually happened.
A flood myth or a deluge myth is a narrative in which a great flood—usually sent by one or more deities—destroys civilization, typically as an act of divine retribution. Parallels are often drawn between the floodwaters of these myths and the primordial cosmic ocean that appears in certain creation myths, because the floodwaters are described as a means of social cleansing or purifying humanity of its corruption, for example, in preparation for rebirth. Most flood myths also feature a culture hero who "represents the human craving for life".

Timeline
How it actually unfolded.
Sumerian King List compiled
The flood is formally recorded in the Sumerian King List, marking a mythological divide between antediluvian and postdiluvian kings. The text documents rulers before and after 'the flood swept over.'
Oral tradition crystallizes
The flood event becomes embedded in Sumerian oral tradition and begins to be formalized into narrative frameworks about divine retribution.
Reconstruction begins
Surviving populations gradually resettle and rebuild settlements in the same river valleys, repeating the cycle of habitation in flood-prone zones.
Flood occurs
A severe flooding event inundates the Mesopotamian river valley, likely caused by convergence of seasonal rains and river surge. Multiple settlements are destroyed or abandoned.

Impact
What followed.
The Great Flood of Mesopotamia became one of humanity's first recorded natural disasters, immortalized in cuneiform texts and later echoed in the Biblical flood narrative. It demonstrated the absolute vulnerability of early river-valley civilizations to environmental forces and shaped religious and mythological frameworks across the ancient Near East for millennia.
