Grid-based city layout

• Cities designed with a precise grid pattern for streets and buildings
• Main streets oriented along cardinal directions (north-south and east-west)
• Divided cities into distinct neighborhoods or sectors
• Incorporated designated areas for public spaces, markets, and craft workshops
• Demonstrated a high level of urban planning rarely seen in contemporary civilizations

Great Bath of Mohenjo-daro

• Large public water tank measuring approximately 12 meters by 7 meters
• Constructed with carefully fitted bricks and a waterproof bitumen lining
• Accessed by steps on either end and surrounded by a colonnade
• Possibly served ritual purification purposes or as a public bathing facility
• Considered one of the earliest examples of public water architecture in the ancient world

Granaries and public buildings

Social structure and governance

• Indus Valley Civilization exhibited a complex social organization
• Provides context for understanding the development of religious and social hierarchies in South Asia
• Offers insights into early forms of urban governance and economic systems

Social hierarchy

• Evidence suggests a relatively egalitarian society compared to contemporaries
• Absence of grand palaces or royal tombs indicates less pronounced social stratification
• Specialized occupations (merchants, artisans, priests) likely formed distinct social groups
• Standardized housing in cities suggests a degree of social equality
• Possible existence of an elite class based on certain artifacts and burial practices

Political organization

• Lack of clear evidence for a centralized monarchy or despotic rule
• Possible governance through a council of elders or merchant oligarchy
• Standardization across the civilization suggests some form of centralized authority
• Cities may have functioned as city-states with a degree of autonomy
• Religious or priestly class might have played a significant role in governance

Trade and economy

• Extensive trade networks both within the civilization and with distant regions
• Exported goods included cotton textiles, beads, and metalwork

• Animal symbolism may reflect early forms of totemism or nature worship

Burial customs

• Practiced both inhumation and cremation burial methods
• Burial sites often located outside city walls or in designated cemeteries
• Grave goods included pottery, jewelry, and personal items
• Some evidence of social differentiation in burial practices
• Possible belief in afterlife based on burial customs and grave offerings

Possible goddess worship

• Terracotta figurines of female forms suggest worship of a mother goddess

• Some figurines depict elaborate headdresses and jewelry, indicating ritual significance
• Possible connection to later Hindu goddess traditions (Shakti, Devi)
• Tree and plant motifs on pottery may be associated with vegetation deities

Decline and legacy

• The decline of the Indus Valley Civilization remains a subject of debate
• Provides insights into the factors that can lead to the collapse of complex societies
• Offers perspective on the long-term impact of early civilizations on later cultural developments

Theories of civilization collapse

• Gradual decline rather than sudden collapse over several centuries
• Possible factors include environmental changes, economic instability, and social upheaval
• Theories of external invasions (Aryan invasion theory) now largely discredited
• Evidence of population movements from urban centers to rural areas
• Decline coincided with the rise of new cultural traditions in the Gangetic plain

Climate change vs invasion debate

• Climate change theory suggests prolonged drought or shifts in monsoon patterns
• Evidence of tectonic activity altering river courses and affecting water availability
• Invasion theory proposed violent conquest by Indo-Aryan groups
• Archaeological evidence does not support large-scale invasion or warfare
• Current consensus favors a combination of environmental and socio-economic factors

Continuity in later Indian culture

• Certain Indus Valley practices and beliefs persisted in later South Asian cultures
• Possible influence on later Hindu religious practices (yoga, animal symbolism)
• Continuity in urban planning concepts and water management techniques
• Legacy in craft traditions (bead-making, metallurgy, pottery styles)

Indus Valley vs other civilizations

• Comparing the Indus Valley Civilization to contemporaneous cultures
• Highlights the unique features and innovations of the Indus Valley society
• Provides context for understanding the development of early urban civilizations

Indus vs Mesopotamia

• Indus cities showed more uniform urban planning compared to Mesopotamian city-states
• Mesopotamia developed cuneiform writing, while Indus script remains undeciphered
• Indus society appeared less militaristic, with fewer signs of warfare
• Both civilizations engaged in long-distance trade and developed sophisticated craft industries
• Mesopotamia had more pronounced social hierarchies and monumental architecture

Indus vs ancient Egypt

• Egypt developed a centralized state with divine kingship, unlike the Indus
• Egyptian writing (hieroglyphs) deciphered, while Indus script remains a mystery
• Indus cities demonstrated more advanced drainage and sanitation systems
• Both civilizations relied on river valley agriculture and developed irrigation techniques
• Egypt focused on monumental architecture (pyramids, temples), while Indus emphasized urban planning

Unique features of Indus culture

Undeciphered script

• Indus script remains one of the world's undeciphered writing systems
• Short inscriptions (average of 5 signs) make decipherment challenging
• Lack of bilingual texts or Rosetta Stone equivalent hinders translation efforts
• Debates over whether the script represents a full writing system or proto-writing
• Computerized analysis and statistical approaches yield some insights but no definitive decipherment

Limited archaeological evidence

• Many Indus sites remain unexcavated or partially excavated
• Modern cities built over ancient sites limit access for archaeologists
• Organic materials poorly preserved due to climate conditions
• Lack of royal tombs or palaces makes it difficult to understand political structures
• Absence of historical texts or records from the civilization itself

Absence of monumental structures

• Lack of grand temples, palaces, or tombs unlike other ancient civilizations
• Challenges interpretations of social hierarchy and religious practices
• Raises questions about the nature of political and religious authority
• Absence of depictions of rulers or religious ceremonies on artifacts
• Difficulties in identifying specific ritual or ceremonial spaces within cities

Theories of Indus religion

• Limited evidence makes reconstruction of religious beliefs speculative
• Debates over the significance of certain artifacts (Proto-Shiva seal, female figurines)
• Uncertainty about the role of priests or religious specialists in society
• Questions about the relationship between Indus beliefs and later South Asian religions
• Challenges in interpreting symbolic motifs on seals and pottery without textual context
