The Indus Valley Civilization entered its late phase, with cities like Mohenjo-Daro declining by 1300 BCE due to climate shifts and migration.
The Shang Dynasty emerged in China around 1600 BCE, introducing advanced bronze casting and early Chinese writing on oracle bones.

Key Developments and Civilizations

This era was defined by the rise and interaction of several influential civilizations across multiple continents. Empires expanded through military conquest, diplomacy, and trade, while writing systems enabled record-keeping and cultural transmission.

Code of Hammurabi: Created around 1755 BCE, this legal code contained 282 laws inscribed on a stone stele and emphasized justice through proportional punishment.

Minoan and Mycenaean cultures: Flourished on Crete and mainland Greece between 2000 and 1200 BCE, developing palatial complexes and early forms of writing.
Assyrian expansion: The Assyrian Empire began consolidating power in northern Mesopotamia around 1350 BCE, laying groundwork for later imperial dominance.
Ugaritic alphabet: Developed around 1300 BCE in Syria, this early alphabetic script influenced later Phoenician and Greek writing systems.
