New research shows the ancient city of Mohenjo-daro experienced a shrinking wealth gap between its richest and poorest households as it prospered [1].
This finding challenges traditional historical assumptions that urban growth and increased prosperity inevitably lead to greater social stratification and inequality. The evidence suggests that early urban success does not require a rigid class hierarchy to sustain economic growth.
The city, which is 4,000 years old [1], appears to have defied the typical rules of history [2]. While most civilizations saw the emergence of powerful royal elites who accumulated vast resources, Mohenjo-daro maintained a more equitable distribution of wealth [1].
Researchers attribute this stability to the city's specific organizational choices. The success of the settlement was driven by shared infrastructure, and fair trade systems [1]. By prioritizing collective resources over individual accumulation, the city prevented the extreme wealth concentration often seen in other ancient urban centers.
"New research reveals that the 4,000-year-old city of Mohenjo-daro defied the 'rules' of history by becoming more equal as it became more successful," a researcher said [2].
This economic model allowed the city to thrive without the presence of a dominant ruling class. As the city's overall wealth increased, the benefits were distributed across a broader segment of the population [1].
"As Mohenjo-daro prospered, the gap between its richest and poorest households actually shrank," a ScienceDaily reporter said [1].
“The 4,000-year-old city of Mohenjo-daro defied the 'rules' of history by becoming more equal as it became more successful.”
The findings from Mohenjo-daro provide a rare archaeological example of 'de-stratification,' where a society becomes more egalitarian during a period of economic growth. This suggests that urban stability and prosperity can be achieved through collective infrastructure and equitable trade rather than through top-down control by a royal or political elite.
