Key Features of the Indus Valley Civilization

Urban Planning and Architecture

The Indus Valley Civilization showcased remarkable urbanization. Cities like Mohenjo-daro and Harappa were designed with exceptional foresight.

Aspect	Details
Grid Layout	Streets intersected at right angles, creating a systematic urban design.
Drainage System	Underground drainage with covered channels for sanitation.
Building Material	Houses and structures were built using uniform baked bricks.
Divided Cities	Cities had a citadel for administrative/religious purposes and a lower residential town.
Great Bath	Found in Mohenjo-daro, likely used for religious or ceremonial purposes.
Granaries	Large storage facilities, indicating surplus food production.

Example:

Mohenjo-daro’s Great Bath: A water-tight tank measuring approximately 12m x 7m, surrounded by steps and dressing rooms.
Harappa's Granary: Rectangular in shape, it served as a central storage hub for grains.

Economic Activities

The economy of the Indus Valley Civilization was diverse, encompassing agriculture, trade, and skilled craftsmanship.

1. Agriculture

Agriculture formed the backbone of the Harappan economy:

Crops: Wheat, barley, mustard, peas, and the earliest evidence of cotton cultivation.
Techniques: Use of plows (as seen in Kalibangan) and irrigation systems.
Animal Husbandry: Domesticated cattle, buffalo, sheep, and goats were integral to farming activities.

2. Trade and Commerce

The Harappans engaged in extensive trade, both locally and internationally.

Internal Trade: Conducted between cities like Harappa, Mohenjo-daro, and Lothal.
External Trade: Evidence of trade with Mesopotamia, referred to as "Meluhha" in Sumerian texts.
Maritime Activities: Lothal, a port city, had a dockyard that facilitated overseas trade.
Barter System: Likely the primary mode of exchange, supported by weights and seals.

3. Craftsmanship

The Harappans were skilled artisans.

Metallurgy: Copper, bronze, gold, and silver were used, though iron was unknown.
Bead-making: Semi-precious stones like carnelian, lapis lazuli, and agate were commonly used.
Pottery: Both painted and wheel-made pottery have been discovered, indicating artistic refinement.

Economic Feature	Details
Agriculture	Cultivated wheat, barley, cotton, and mustard.
Trade Partners	Mesopotamia, Oman, and Central Asia.
Artifacts	Seals, beads, pottery, and tools reflect skilled craftsmanship.

Social and Cultural Life

The Harappans displayed a cohesive social organization and a unique cultural identity.

1. Society

Social Structure: Evidence suggests a relatively egalitarian society with no grand palaces or large burial sites indicating ruling elites.
Housing: Homes ranged from single-room dwellings to multi-room buildings, reflecting a mix of classes.

2. Religion

Mother Goddess: Terracotta figurines represent fertility worship.
Pashupati Seal: A figure resembling Lord Shiva surrounded by animals, suggesting early Hindu elements.
Nature Worship: Symbols like trees, animals, and sacred figures indicate nature-based spirituality.

3. Art and Writing

Art: The bronze figurine of the "Dancing Girl" from Mohenjo-daro reflects artistic excellence.
Writing: The Indus script, found on seals and pottery, remains undeciphered. It likely consisted of pictographs.

Major Sites of the Indus Valley Civilization

Site	Location	Unique Features
Harappa	Punjab, Pakistan	Granaries, seals, and a well-planned city layout.
Mohenjo-daro	Sindh, Pakistan	Great Bath, advanced drainage, and multi-story houses.
Lothal	Gujarat, India	Dockyard, bead-making industry, and trade links.
Dholavira	Gujarat, India	Water reservoirs, unique city design, and inscriptions.
Kalibangan	Rajasthan, India	Plowed field remains, fire altars, and terracotta bangles.
Rakhigarhi	Haryana, India	Largest Harappan site with evidence of urban planning.

The Decline of the Indus Valley Civilization

The reasons behind the decline of this advanced civilization are not definitively known, but several theories have been proposed:

Theory	Details
Climate Change	Shifts in monsoons and prolonged droughts disrupted agriculture.
Floods and Earthquakes	Geological evidence points to recurring natural disasters causing urban decay.
Resource Overuse	Overexploitation of natural resources may have weakened the economy.
Migration	Evidence suggests gradual abandonment of cities, possibly due to ecological stress.

Modern research increasingly points to environmental changes and gradual societal shifts as the primary factors for decline.

Significance of the Indus Valley Civilization

The Indus Valley Civilization offers deep insights into early urban culture:

Urban Planning: A model of organized city life that continues to inspire modern urbanization.
Trade and Economy: A precursor to complex trade systems and economic activities.
Cultural Legacy: Practices like water conservation, craftsmanship, and urban sanitation have contemporary relevance.

Aspect	Modern Relevance
Urban Planning	Influences today’s city designs with grid systems and drainage planning.
Economic Practices	Highlights sustainable agriculture and resource management.
Cultural Influence	Proto-Hindu elements like the Pashupati Seal link ancient and modern traditions.

Conclusion
