# Harappan Civilization The Indus Valley Civilization, also known as the Harrapan Civilization, was a [[Bronze Age]] civilization more widespread than its contemporaries in either [[China]], [[Mesopotamia]] or ancient [[Egypt]]. The civilisation's cities were noted for their urban planning, baked brick houses, elaborate [[2022-08-01 Sewers|drainage]] systems, water supply systems, clusters of large non-residential buildings, and new techniques in handicraft (carnelian products, seal carving) and metallurgy (copper, bronze, lead, and tin). Its largest cities probably had between 30,000 and 60,000 inhabitants, which led to an increased death and disease rate due to the intermingling of people and [[domestication|domesticated]] animals. - [[climate change caused the decline of Harrapa]] - They're [excavating a 7,000 year old planned city](https://www.archaeology.org/news/10537-220511-india-rakhigarhi-jewelry) right now, with [[funerary practices]] and drainage systems and multi-story houses having been discovered, which is pretty relevant for [[Infrastructure in Ancient Civilizations]]. ## Agriculture The Harrapan are the earliest people to use complex multi-cropping strategies across both seasons, growing foods during summer (rice, millets and beans) and winter (wheat, barley and pulses), which required different watering regimes.[^agriculture] [^agriculture]: In the [[Nahrian Basin]], [[The Gardener]] would be responsible for ensuring that this sort of methodology is used.
