When did Indus valley civilization took place?

The Indus Valley Civilization, one of the world's earliest urban cultures, flourished between approximately 3300 BCE and 1300 BCE. It was centered around the Indus River basin, primarily in present-day Pakistan and northwest India. The civilization is known for its advanced city planning, architecture, and social organization, with significant urban centers like Harappa and Mohenjo-Daro. The decline of this civilization is believed to have occurred around 1900 BCE, possibly due to climate change, shifting river patterns, or invasions.
