1. The Indus Valley Civilization (3300–1300 BCE)
One of the world’s earliest urban cultures, the Indus Valley Civilization had well-planned cities like Harappa and Mohenjo-Daro, with advanced drainage systems and trade networks. Yet, by 1900 BCE, people abandoned these cities.

Possible Reasons for Decline:
Climate change (droughts, shifting river patterns)
Aryan migration theory (debated due to lack of evidence)
Economic collapse (decline in trade)
Mystery: No signs of war or natural disasters—just an eerie, gradual abandonment.


2. The Minoan Civilization (2700–1450 BCE)
Known for the palace of Knossos in Crete, the Minoans were master traders and artists. Around 1450 BCE, their civilization collapsed suddenly.
Theories Behind Their Fall:
Thera volcano eruption (tsunamis, ash clouds)
Mycenaean invasion (Greek warriors taking over)
Economic disruption (trade routes destroyed)
Mystery: Their writing (Linear A) remains undeciphered, hiding crucial clues.


3. The Olmec Civilization (1400–400 BCE)
The “Mother Culture” of Mesoamerica, the Olmecs built colossal stone heads and influenced the Maya and Aztecs. By 400 BCE, their cities were abandoned.
Possible Causes:
Environmental changes (river course shifts)
Internal conflict (social unrest)
Rise of rival civilizations (Zapotecs, Maya)
Mystery: No written records—only giant stone heads staring silently.


4. The Ancestral Puebloans (Anasazi) (100–1300 CE)
Famous for cliff dwellings in Mesa Verde, the Ancestral Puebloans thrived in the American Southwest before vanishing around 1300 CE.

Why Did They Leave?
Severe drought (tree-ring evidence)
Resource wars & cannibalism (controversial theory)
Migration to new regions (modern Pueblo tribes)
Mystery: Their stone cities remain intact, but the people simply left.


5. The Mycenaean Civilization (1600–1100 BCE)
The Mycenaeans, heroes of Homer’s Iliad, built grand palaces like Mycenae and Tiryns. Yet, by 1100 BCE, their civilization collapsed.
Possible Reasons:
Invasion by the Sea Peoples
Earthquakes & internal rebellions
Economic collapse (trade networks failing)
Mystery: Their writing (Linear B) disappeared, leading to Greece’s Dark Age.
