History

The Indus Valley Civilization (IVC) was a Bronze Age civilization (3300 1300 BCE; mature period 2600 1900 BCE) in the northwestern region of the Indian subcontinent,consisting mainly of what is now Pakistan, and parts of India, Afghanistan and Iran.Flourishing around the Indus River basin, the civilization extended east into the Ghaggar-Hakra River valley and the upper reaches of Ganges-Yamuna Doab it extended west to the Makran coast of Balochistan, north to northeastern Afghanistan and south to Daimabad in Maharashtra.

The Indus Valley Civilization is also known as the Harappan Civilization, as the first of its cities to be unearthed was located at Harappa, excavated in the 1920s in what was at the time the Punjab province of British India (now in Pakistan). Excavation of Harappan sites has been ongoing since 1920, with important breakthroughs occurring as recently as 1999. There were earlier and later cultures, often called Early Harappan and Late Harappan, in the same area of the Harappan Civilization.
