The study of standardized brick sizes and grid-patterned streets in the Indus Valley suggests a high degree of centralized political authority as early as 2600 BCE. Such uniformity across vast distances implies a coordinated effort to regulate construction and urban life, even in the absence of monumental palaces or royal tombs. Critics of this view argue that communal consensus among merchant guilds could explain the standardization without the need for a singular ruling elite. However, the sheer scale of the drainage systems and the consistency of weight systems used in trade suggest a level of oversight that typically requires a formal administrative structure. This debate highlights the difficulty of inferring social hierarchy from purely material remains.
