What is the evidence of social organization in the Indus Valley Civilization?

The evidence of social organization in the Indus Valley Civilization includes the presence of well-planned cities with sophisticated urban infrastructure, such as grid-like street layouts, advanced drainage systems, and public buildings. The existence of standardized weights and measures suggests a centralized authority overseeing trade and commerce. The presence of large public structures, such as the Great Bath and the Granary, indicates the existence of a hierarchical society with specialized labor. Additionally, the discovery of seals and inscriptions suggests the presence of a writing system and possibly a bureaucratic administration.
