The Indus Valley Civilization was one of the world’s earliest urban civilizations, flourishing in South Asia from about 2600 BCE to 1900 BCE. Its major cities, including Mohenjo-daro and Harappa, were carefully planned with straight streets, baked-brick buildings, wells, and drainage systems. Studying this civilization helps students see how early societies solved problems of housing, sanitation, trade, and community organization.
It also shows that advanced cities developed in more than one region of the ancient world.
Key Facts
- The Indus Valley Civilization flourished mainly from about 2600 BCE to 1900 BCE.
- Major cities included Mohenjo-daro, Harappa, Dholavira, and Kalibangan.
- Cities used grid-like street plans, baked bricks, wells, and covered drainage channels.
- The civilization traded goods such as beads, pottery, cotton textiles, and metals with nearby regions and Mesopotamia.
- Indus writing has not been fully deciphered, so historians rely on archaeology for much of what they know.
- The civilization declined gradually, likely because of environmental change, shifting rivers, reduced trade, and other combined causes.
Vocabulary
- Urban planning
- Urban planning is the organized design of a city, including its streets, buildings, water systems, and public spaces.
- Mohenjo-daro
- Mohenjo-daro was a major Indus city in present-day Pakistan known for its planned streets, drainage system, and large public structures.
- Harappa
- Harappa was an important Indus city that gives its name to the Harappan culture of the Indus Valley Civilization.
- Granary
- A granary is a building or storage area used to hold grain and protect food supplies.
- Archaeology
- Archaeology is the study of past human life through objects, buildings, tools, and other physical remains.
Common Mistakes to Avoid
- Calling the Indus Valley Civilization primitive is wrong because its cities had advanced planning, drainage, craft production, and trade networks.
- Assuming kings and palaces are well documented is wrong because archaeologists have not found clear evidence of large royal tombs or obvious palaces like those in Egypt or Mesopotamia.
- Treating the Indus script as fully readable is wrong because scholars have not yet deciphered it with certainty, so many details about language and government remain unknown.
- Saying the civilization ended suddenly from one single cause is wrong because evidence points to a gradual decline influenced by climate, river changes, trade shifts, and local adaptations.
Practice Questions
- 1 If Mohenjo-daro flourished around 2500 BCE and a student is studying it in 2025 CE, about how many years ago was that? Show your calculation.
- 2 The Mature Harappan period lasted from about 2600 BCE to 1900 BCE. How many years did this period last?
- 3 Explain how wells, drains, and organized streets could improve daily life in an Indus city and what they suggest about community planning.
