• The Harappan Civilization, also known as the Indus Valley Civilization, flourished during the Bronze Age, approximately between 3300 BCE and 1300 BCE.

• This civilization is characterized by its use of bronze to craft tools, weapons, and other artifacts, signifying advanced metallurgy skills.

• The Harappans extensively utilized copper and tin to create bronze, which was a major technological advancement of the era.

• Artifacts like bronze statues, tools, and seals were discovered at Harappan sites, showcasing their sophistication in metalworking.

• Major urban centers of the Harappan Civilization, such as Harappa, Mohenjo-Daro, and Dholavira, demonstrate their advancements in architecture, urban planning, and trade during the Bronze Age.![image](//cdn. Information**

• Iron Age

• The Iron Age succeeded the Bronze Age and began around 1200 BCE in some regions.

• This era was marked by the widespread use of iron for tools and weapons, replacing bronze due to its greater abundance and durability.

• The Iron Age saw the development of more advanced agricultural tools and military equipment, significantly impacting societal structures.

• However, the Harappan Civilization predates the Iron Age and thus does not belong to this period.

• Stone Age

• The Stone Age refers to the prehistoric period when humans primarily used stone tools.

• It is divided into three phases: Paleolithic (Old Stone Age), Mesolithic (Middle Stone Age), and Neolithic (New Stone Age).

• The Harappan Civilization cannot be classified under the Stone Age, as it demonstrates advanced technologies like metallurgy and urban planning.

• Paleolithic Age

• The Paleolithic Age is the earliest phase of the Stone Age, marked by the use of rudimentary stone tools by early humans.

• This period is characterized by a hunter-gatherer lifestyle and the absence of settled communities.

• The Harappan Civilization, being a highly developed and urbanized society, is far removed from the characteristics of the Paleolithic Age.
