• Classical Period (600 BCE-600 CE) witnessed the rise of Greek city-states, Roman Empire, and Han Dynasty in China
• Decline of early civilizations occurred due to various factors, including invasions, environmental changes, and internal strife (Roman Empire fell in 476 CE, Han Dynasty fell in 220 CE)

Major Civilizations Overview

• Mesopotamia (Sumer, Akkad, Babylon, Assyria) developed in the Tigris-Euphrates River Valley
  • Known for the development of writing, codified laws (Code of Hammurabi), and impressive architecture (ziggurats)
• Ancient Egypt flourished along the Nile River
  • Characterized by a strong central government, complex religion, and monumental architecture (pyramids, temples)
• Indus Valley Civilization (Harappa and Mohenjo-Daro) thrived in present-day Pakistan and India
  • Advanced urban planning, standardized weights and measures, and enigmatic script
• Ancient China emerged along the Yellow River (Huang He)
  • Dynasties such as Shang, Zhou, Qin, and Han unified the region and made significant advancements in technology, philosophy, and governance
• Mesoamerican civilizations (Olmec, Maya, Aztec) and Andean civilizations (Chavín, Moche, Inca) developed independently in the Americas
  • Known for their impressive architecture, astronomy, and agriculture

Environmental Factors and Geography

• River valleys provided fertile soil, water for irrigation, and transportation routes, enabling the growth of agriculture and trade (Nile, Tigris-Euphrates, Indus, Yellow)
• Seasonal flooding replenished soil nutrients and allowed for predictable agricultural cycles
  • Egyptian civilization relied on the annual Nile floods for agriculture
• Geographical barriers (deserts, mountains, seas) provided natural protection and helped shape distinct cultures
  • The Himalayas and the Taklamakan Desert isolated ancient China, contributing to its unique cultural development
• Access to resources (timber, stone, metals) influenced the development of technologies and trade networks
• Climate changes (droughts, floods) could disrupt agriculture and lead to social and political instability
  • Prolonged drought may have contributed to the decline of the Indus Valley Civilization

Technological Advancements

• Development of agriculture and irrigation techniques allowed for surplus food production and population growth
  • Sumerians invented the plow and developed complex irrigation systems
• Invention of the wheel revolutionized transportation and pottery production (potter's wheel)
• Metallurgy advancements led to the production of bronze and iron tools, weapons, and jewelry
  • Iron tools improved agricultural efficiency and military capabilities
• Writing systems emerged to record information, maintain records, and communicate across distances
  • Egyptian hieroglyphs, Mesopotamian cuneiform, Chinese oracle bones
• Advancements in architecture and engineering enabled the construction of monumental structures
  • Egyptian pyramids, Mesopotamian ziggurats, Great Wall of China
• Innovations in astronomy, mathematics, and medicine laid the foundation for future scientific developments
  • Babylonians developed a base-60 number system and made accurate astronomical observations

Social Structures and Governance

• Early civilizations were characterized by hierarchical social structures and the emergence of ruling classes
  • Egyptian society divided into pharaoh, nobles, priests, scribes, and commoners
• Centralized governments, often led by kings or emperors, administered the state and maintained order

Economic Systems and Trade

• Agriculture formed the basis of most early civilizations' economies
  • Crops such as wheat, barley, rice, and maize were staples

  • Egyptian tax collectors, Inca mit'a labor tax system
• Maritime trade expanded the reach of civilizations and fostered cultural exchange
  • Phoenicians and Greeks established colonies and trading posts throughout the Mediterranean

Cultural and Religious Developments

• Polytheistic religions were common, with pantheons of gods and goddesses representing natural forces and human attributes
  • Mesopotamian deities (Enki, Marduk), Egyptian deities (Ra, Osiris, Isis), Greek deities (Zeus, Athena, Apollo)

Factors Leading to Decline

• Invasions and conquests by neighboring civilizations or nomadic groups disrupted political stability and trade networks
  • Indo-European migrations, Persian conquest of Mesopotamia, Germanic invasions of the Roman Empire
• Environmental factors, such as climate change, deforestation, and soil erosion, could lead to agricultural failures and population decline
  • Deforestation and soil salinization in Mesopotamia, drought in the Indus Valley
• Internal political instability, civil wars, and power struggles weakened central authority
  • Warring States period in China, Third Century Crisis in the Roman Empire
• Economic factors, such as the loss of trade routes, depletion of resources, or excessive taxation, could contribute to decline
  • Collapse of Mediterranean trade after the fall of the Roman Empire
