Indus Valley Civilization UPSC : Features and Decline

The Indus Valley Civilization, also known as the Harappan Civilization, is one of the world’s earliest urban cultures. It flourished around 3300 BCE–1300 BCE in what is now Pakistan and northwest India. This ancient civilization is renowned for its advanced city planning, remarkable architecture, and sophisticated drainage systems. It showcases a high degree of social and technological development.

Key Indus Valley civilization sites like Harappa, Mohenjo-Daro, and Dholavira exhibit a level of planning and organization that was unparalleled at the time. These cities featured grid layouts, standardized bricks, and elaborate drainage systems, reflecting a strong central authority and meticulous urban governance. The civilization’s script, which remains undeciphered, suggests a complex and rich communication system, pointing to an advanced socio-economic structure.

Despite its remarkable achievements, the Indus Valley Civilization’s decline around 1900 BCE remains a subject of debate among historians. Various theories, including environmental changes, tectonic activities, and invasions, have been proposed to explain its mysterious disappearance. The study of this ancient civilization provides valuable insights into the early development of human societies and their interaction with the environment.

Historical Context and Discovery

The Indus Valley Civilization (IVC), dating back to around 3300 BCE, is one of the world’s earliest urban cultures. It is primarily located in present-day Pakistan and northwest India. Its historical significance lies in its advanced urban planning, architecture, and social organization. The discovery of the IVC began in the 1920s at Harappa and Mohenjo-Daro by archaeologists like Sir John Marshall. The findings revealed a sophisticated and widespread civilization. They challenged previous notions about ancient societies and highlighted the complexity of early human history in the Indian subcontinent.

Chronology and Geographical Spread

The Indus Valley civilization was primarily located in the Indus River valley, with its major urban centers at Harappa and Mohenjo-Daro. It extended over a vast area, from Balochistan to Gujarat, with more than 1,000 towns and villages. The civilization is typically divided into three phases: the Early Harappan(3300 to 2600 BCE), Mature Harappan(2600-1900 BCE), and Late Harappan(1900-1300 BCE) phases.

Discovery and Excavation

The ruins of the civilization were first identified by Charles Masson in 1826. The systematic excavations began much later in the 1920s by Sir John Marshall. He discovered the great cities of Harappa and Mohenjo-Daro, revealing a civilization of immense complexity and technological advancement.

Town Planning of Indus Valley Civilization

The Indus Valley Civilization is renowned for its advanced urban planning and architecture. Cities like Harappa and Mohenjo-Daro were laid out in a grid pattern. They featured wide streets and well-planned residential and public areas. Buildings were constructed with standardized baked bricks, showcasing remarkable uniformity. Notable architectural achievements include sophisticated drainage systems, with covered drains and sewage facilities, and impressive public structures like the Great Bath of Mohenjo-Daro. The uniformity and precision in urban planning reflect a highly organized central authority and an advanced understanding of civil engineering and urban governance.
