Indus Valley civilization
The Indus Valley civilization or the Harrapan civilization (3300–1300 BC; mature period 2700–1700 BC) was a Bronze Age civilization around the Indus river in Pakistan.[1] It is among the four oldest civilisations in the world and also the earliest known urban culture of South Asia.[2][3] It also covered some areas of western India and had a trading colony in Afghanistan.[4] It was discovered by archaeologists in the 1880s. It developed along the Indus and the Ghaggar-Hakra rivers.It is one of the world’s three earliest civilizations, along with Mesopotamia and Ancient Egypt.[5]
The civilization started during the Bronze Age and the height of its development was between 2500 BC and 1500 BC. Including the civilizations directly before and after, it may have lasted from the 3rd to the 14th century BC.[6][7] Its two large cities are Harappa and Mohenjo-daro in Pakistan’s Punjab and Sindh provinces. The ruins of Mohenjo-daro were designated a UNESCO World Heritage site in 1980.[8]
The Indus Valley civilization covered a large area – from most of modern Pakistan to small parts of western India. The first city to be discovered by excavation (digging up) was Harappa in Punjab, Pakistan and so this civilization is also called the 'Harappan Civilization'.
They were good builders. The ruins of the site shows skillful design. Their buildings had two or sometimes more stories. The bathrooms were attached to the rooms. One of the unique features of the city was its elaborate drainage system. A brick-lined drainage channel flowed alongside every street. Removable bricks were placed at regular intervals for easy cleaning and inspection.
The Harappan traders used seals on the knots of the sacks to be transported to make sure that they were not opened during the journey. Nobody knows how to read their writing system.
In 1842 Charles Masson wrote a book that mentioned the sites of Indus Valley Civilisation.[9] Few people paid attention. Later, in 1921/22, John Marshall organised the first archaeological dig at Harappa.[10]
