Mohenjo- Daro

Mohenjo-daro (Mound of the Dead) was one of the largest city-settlements of the Indus Civilization of south Asia located in the province of Sind, Pakistan. Mohenjo-daro was built around 2600 BC and abandoned around 1900 BC, the city was one of the early urban settlements in the world, existing at the same time as the civilizations of ancient Egypt, Mesopotamia, and Crete.
Mohenjo-daro is located in the Sindh province on a Pleistocene ridge in the middle of the flood plain of the Indus River. The ridge is now buried by the flooding of the plains, but was prominent during the time of the Indus Valley Civilization. The ridge allowed the city to stand out above the surrounding plain and be elevated. The site is situated in a central position between the Indus river valley on the west and the Ghaggar-Hakra on the east. In the modern day, the Indus still flows to the east of the site, but the Ghaggar-Hakra riverbed is dry.
Mohenjo-daro in ancient times was most likely one of the administrative centers of the ancient Indus Valley Civilization. It was the most developed and advanced city in South Asia, and perhaps the world, during its peak. The planning and engineering showed the importance of the city to the people of the Indus valley.
The Indus Valley Civilization (c. 3300–1700 BC, flowered 2600–1900 BC), was an ancient riverine civilization that flourished in the Indus river valley in Pakistan and north-west India. Another name for this civilization is the "Harappan Civilization."
The Indus culture blossomed over the centuries and gave rise to the Indus Valley Civilization around 3000 BCE. The civilization spanned much of what is now Pakistan and North India, but suddenly went into decline around 1900 BCE. Indus Civilization settlements spread as far south as the Arabian Sea coast of India in Gujarat, as far west as the Iranian border, with an outpost in Bactria. Among the settlements were the major urban centers of Harappa and Mohenjo-daro, as well as Lothal.
The Mohenjo-daro ruins were one of the major centres of this ancient society. At its peak, some archaeologists opine that the Indus Civilization may have had a population of well over five million.
To date, over a thousand cities and settlements have been found, mainly in the Indus River valley in Pakistan and northwestern India.
