Pataliputra was a major city in ancient India that rose to prominence much later, serving as the capital for the Mauryan and Gupta empires. Lothal, Rangpur, and Sutkagan Dor are all established sites of the earlier Harappan civilization.

The Indus economy was multifaceted. While intensive agriculture (wheat, barley) provided the foundation, the civilization flourished due to large-scale trade networks and specialized crafts. This economic stability supported their elegant social structure and urban development.

The Harappans utilized standardized baked (pucca) bricks for construction, which was a distinct feature compared to contemporary civilizations that often used mud bricks. Houses were typically one or two stories high with flat roofs and focused on privacy, with windows opening into courtyards rather than the street.

Dholavira is a site of immense importance due to its sophisticated system of reservoirs and dams. Unlike other sites, it demonstrates advanced engineering dedicated to water harnessing and conservation, sustaining the city for over 1,200 years.

Kalibangan is most renowned for its unique pottery traditions. The ceramics found here bear a close resemblance to the Hakra ware found in Cholistan and other Early Harappan pottery, distinguishing it within the Integration Era of the civilization.

Lothal is famous for housing the world's earliest known dockyard. This brick structure connected the city to an ancient course of the Sabarmati river, establishing a vital trade route between Harappan cities in Sindh and the Saurashtra peninsula when the surrounding Kutch desert was part of the Arabian Sea.

While the two major capitals (Harappa and Mohenjo-Daro) are in Pakistan, the highest number of total sites discovered so far are located in India (e.g., in Gujarat, Haryana, Rajasthan).

Chanhudaro yielded evidence of cosmetics use, including a lipstick-like object, highlighting the grooming culture of the time.

It was named so because the initial major sites (like Mohenjo-Daro) were discovered along the banks of the Indus River system.

A terracotta toy model of a plough was found at Banawali (Haryana), indicating the use of ploughs in agriculture.
