Answer:
The Indus River Valley Civilization, 3300-1300 BCE, also known as the Harappan Civilization, extended from modern-day northeast Afghanistan to Pakistan and northwest India.
Important innovations of this civilization include standardized weights and measures, seal carving, and metallurgy with copper, bronze, lead, and tin.
Little is understood about the Indus script, and as a result, little is known about the Indus River Valley Civilization’s institutions and systems of governance.
The civilization likely ended due to climate change and migration.
