Answer:
Explanation:
The Indus Valley Civilization (also known as the Harappan Civilization) was a Bronze Age society extending from modern northeast Afghanistan to Pakistan and northwest India.
The civilization developed in three phases: Early Harappan Phase (3300 BCE-2600 BCE), Mature Harappan Phase (2600 BCE-1900 BCE), and Late Harappan Phase (1900 BCE-1300 BCE).
Inhabitants of the ancient Indus River valley developed new techniques in handicraft, including Carnelian products and seal carving, and metallurgy with copper, bronze, lead, and tin.
Sir John Hubert Marshall led an excavation campaign in 1921-1922, during which he discovered the ruins of the city of Harappa. By 1931, the Mohenjo-daro site had been mostly excavated by Marshall and Sir Mortimer Wheeler. By 1999, over 1,056 cities and settlements of the Indus Civilization were located.
