The discovery of the Harappan civilization was a result of significant efforts by several archaeologists:
Daya Ram Sahni (1921): Conducted the first excavations at Harappa, uncovering the remains of a highly developed urban culture. He unearthed seals, pottery, and structural remains.
R.D. Banerji (1922): Discovered Mohenjo-Daro, another major Harappan site, and identified its advanced urban planning and drainage systems.
John Marshall: As the Director-General of the Archaeological Survey of India, Marshall recognized the significance of these findings and formally announced the discovery of the Indus Valley Civilization in 1924.
Mortimer Wheeler: Used the stratigraphy method to analyze Harappan layers, contributing to a better understanding of the civilization’s chronology and urban structures.
E.J.H. Mackay: Conducted detailed excavations at Harappa and Mohenjo-Daro, revealing insights into daily life, trade, and craftsmanship.
These archaeologists collectively shed light on one of the oldest civilizations, highlighting its urban sophistication and cultural significance.

The orders of the king
Thus speaks king Devanampiya Piyadassi: In the past, there were no arrangements for disposing affairs, nor for receiving regular reports. But I have made the following (arrangement).

And I will dispose of the affairs of the people everywhere.
