Mohenjodaro

Mohenjo-daro is located in the Larkana District of Sindh, Pakistan, on a Pleistocene ridge in the middle of the flood plain of the Indus River Valley, around 28 kilometres (17 mi) from the town of Larkana. The ridge was prominent during the time of the Indus Valley Civilization, allowing the city to stand above the surrounding plain, but the flooding of the river has since buried most of the ridge in deposited silt. The site occupies a central position between the Indus River and the Ghaggar-Hakra River. The Indus still flows to the east of the site, but the riverbed of the Ghaggar-Hakra on the western side is now dry.
 Mohenjo-daro was most likely one of the largest cities of the ancient Indus Valley Civilization, also known as the Harappan Civilization (after Harappa, another important IVC site, which is located to the north of Mohenjo-daro in Punjab, Pakistan). The prehistoric Indus culture gave rise to the Indus Valley Civilization around 3000 BC. The civilization spanned much of what is now Pakistan and North India, but suddenly went into decline around 1900 BC. Indus Civilization settlements spread as far west as the Iranian border, with an outpost in Bactria, and as far south as the Arabian Sea coast of western India in Gujarat. Among the settlements were the major urban centers of Harappa and Mohenjo-daro, as well as Lothal. At its height, Mohenjo-daro was the most developed and advanced city in ancient South Asia, displaying remarkably sophisticated engineering and urban planning for its time.

Rediscovery and excavation

Mohenjo-daro was built in the 26th century BC, and oned around 1800 BC. The ruins of the city were discovered in 1922 by Rakhaldas Bondopadya an officer of thopade Archaeological Survey of India. He was led to the mound by a Buddhist monk, who reportedly believed it to be a stupa. In the 1930s, major excavations were conducted at the site under the leadership of John Marshall, K. N. Dikshit and Ernest Mackay^.. exacavations were carried out in 1945 by Ahmad Hasan Dani and Mortimer Wheeler.
The last major series of excavations were conducted in 1964 and 1965 by Dr. George F. Dales. After this date, excavations were banned due to weathering damage to the exposed structures, and the only projects allowed at the site since have been salvage excavations, surface surveys and conservation projects. However, in the 1980s, German and Italian survey groups led by Dr. Michael Jansen and Dr. Maurizio Tosi used less invasive archeological techniques, such as architectural documentation, surface surveys and localized probing, to gather further information about Mohenjo-daro.
