Debated. A study reads everyday houses and seals as a city that grew fairer, but that reading is still argued.
Mohenjo-daro was a great Indus city about 4,000 years old. Researchers compared the sizes of its houses. The page says the gap between the largest and smallest homes grew smaller as the city grew. Indus seals, used for business and trade, were usually found in ordinary homes, not in public buildings. The page says there were no palaces where a ruler kept those seals. The city put its work into brick-lined drains and planned streets. People across the region used the same weights and measures.
People still argue about whether the city really became more equal as it grew.
