Overview
The lecture covers the development, key features, and contributions of ancient river valley civilizations, focusing on Mesopotamia and the Indus Valley, their geography, innovations, and societal structures.
Ancient River Valley Civilizations
- Major civilizations developed along rivers: Mesopotamia (Tigris-Euphrates), Egypt (Nile), Indus, and China (Yellow River).
- Rivers provided fertile land, water for agriculture, and enabled trade and transportation.
- Cities, writing systems, governments, and laws emerged in these regions, forming the foundation for modern societies.
Mesopotamia
- Known as the "Cradle of Civilization" for the emergence of cities and written law.
- Significant contributions: Code of Hammurabi (law code), Hanging Gardens of Babylon, and ziggurats (temple structures).
- Lex talionis is the principle that punishment should match the crime ("an eye for an eye").
- The division of labor allowed specialization, improving agricultural and societal development.
- Nebuchadnezzar II built the Hanging Gardens for his wife Amitis.
Indus Valley Civilization
- Located in present-day Pakistan, India, and Afghanistan along the Indus River.
- Main cities: Harappa and Mohenjodaro, known for planned layouts and citadels.
- Achievements include urban planning (grid layouts), advanced drainage, use of bricks, and seals for trade.
- Developed a pictogram writing system that remains undeciphered.
- Practiced trade as far as Mesopotamia and used standardized weights and measures.
- Houses were made of sun-dried bricks, with bronze and copper furniture.
- Artifacts show detailed art and jewelry.
- Civilization decline possibly due to river changes or invasion by Aryan people.
Indian Subcontinent Geography
- Three main zones: Northern Plains (fertile, river-fed), Deccan Plateau (dry, less suitable for farming), and Coastal Plains (ideal for agriculture, fishing, and trade).
- The Himalayas and Hindukush mountains served as natural barriers; Kyber Pass allowed access for invaders.
Legacy and Decline
- The Aryans introduced the caste system, influencing social structure and Hinduism.
- The Indus Valley's urban planning and public infrastructure influenced later developments.
- Disappearance linked to environmental changes or external conquest.
