History of Mohenjo-daro
The city was built around 2500 BCE and flourished for centuries as one of the largest settlements of the Indus Valley Civilisation, alongside Harappa in Punjab. It was abandoned around 1700 BCE as the civilisation declined. Population estimates of about 40,000 at its peak are rough, but the scale is obvious once you walk its streets.
Its real name is unknown. “Mohenjo-daro” is usually read in Sindhi as “Mound of the Dead”. R. D. Banerji of the Archaeological Survey of India recognised the site in 1919–1920, and major excavations followed in the mid-1920s under Kashinath Dikshit and Sir John Marshall.
Large-scale digging stopped after 1965 because exposed walls were decaying, and today conservation is the priority. Salt rising through the bricks is the main threat, and heavy rain in August 2022 damaged parts of the site; UNESCO and ICOMOS experts reviewed the repairs in March 2024 (UNESCO report).
