Aspects of Harappan Economy:
The Harappan civilization, also known as the Indus Valley civilization, had a well-developed economy that supported its urban centers. Based on archaeological evidence, several aspects of the Harappan economy have been reconstructed:

Trade and Commerce:
- The Harappans were engaged in long-distance trade with regions like Mesopotamia, Central Asia, and the Persian Gulf.
- Archaeological findings of seals, weights, and pottery suggest a sophisticated trade network.
- The presence of dockyards at sites like Lothal indicates maritime trade.

Agriculture:
- The Harappans practiced advanced agricultural techniques such as irrigation, evidenced by the presence of well-planned drainage systems and reservoirs.
- Wheat, barley, peas, and sesame were some of the crops cultivated by the Harappans.

Crafts and Industries:
- The Harappans were skilled in crafts like pottery, metalworking, and bead-making.
- They produced goods such as jewelry, seals, tools, and pottery for trade and local consumption.
- Evidence of specialized craft neighborhoods suggests a division of labor.

Urban Planning and Infrastructure:
- The well-planned cities of the Harappan civilization, with grid-like streets and standardized brick sizes, indicate centralized planning.
- The presence of granaries and public baths suggests a sophisticated urban infrastructure.

Social Organization and Economy:
- The presence of a standardized weight system and seals for trade indicates a centralized authority overseeing economic activities.
- The absence of palaces or temples suggests a relatively egalitarian society where economic activities were decentralized.
In conclusion, the Harappan economy was characterized by trade, advanced agricultural practices, skilled craftsmanship, urban planning, and a complex social organization. These aspects, reconstructed from archaeological evidence, provide insights into the economic system of this ancient civilization.
