Indus Valley civilization
The Indus Valley civilization was an ancient civilization. It was discovered by archaeologists in the 1920s. It developed along the Indus River and the Ghaggar-Hakra River, in the area of modern Pakistan. It started during the Bronze Age. The height of its development was between 2600 and 1900 BCE. Including the civilizations directly before and directly afterward, it may have lasted from the 33rd to the 14th century BCE.
The Indus Valley Civilization covered a large area - from Balochistan (Pakistan) to Gujarat (Republic of India). Today some old remains of the Indus Valley Civilization can be found in Afghanistan, Turkmenistan and Iran. The first city to be discovered by excavation (digging up) was Harappa and therefore this civilization is also known as 'Harappan Civilization'. The bathrooms were attached to the rooms of the Harappa people. They were considered to be good builders.It brought tremendous change in the country in various ways. The ruins of the sight reveal that the harappa civilization people were skillful designers. Their buildings had two or sometimes more stories. One of the unique features of the city was its elaborate drainage system. A brick-lined drainage channel flowed along side every street. Removable bricks were placed at regular intervals for easy cleaning and inspection. The Harappans were advanced enough to play dice games. The harappan businessmen used seals that were put on the knots of the sacks that were to be transported to ensure that they were not opened during the journey.
