The Indus Valley Civilization (IVC) was a Bronze Age civilization (3300–1300 BCE; mature period 2600–1900 BCE) located in the western region of South Asia, and spread over what are now Pakistan, northwest India, and eastern Afghanistan. Flourishing in the Indus River basin, the civilization extended east into the Ghaggar-Hakra River valley and the upper reaches Ganges-Yamuna Doab; it extended west to the Makran coast of Balochistan and north to northeastern Afghanistan. The civilization was spread over some 1,260,000 km², making it the largest ancient civilization.
The Indus Valley is one of the world's earliest urban civilizations, along with its contemporaries, Mesopotamia and Ancient Egypt. At its peak, the Indus Civilization may have had a population of well over five million. Inhabitants of the ancient Indus river valley developed new techniques in metallurgy and handicraft (carneol products, seal carving) and produced copper, bronze, lead, and tin. The civilization is noted for its cities built of brick, roadside drainage system, and multistoried houses.
Civilization (or civilisation) is a sometimes controversial term that has been used in several related ways. Primarily, the term has been used to refer to the material and instrumental side of human cultures that are complex in terms of technology, science, and division of labor. Such civilizations are generally hierarchical and urbanized. In a classical context, people were called "civilized" to set them apart from barbarians, while in a modern-day context, "civilized peoples" have been contrasted with primitive peoples.
There is a tendency to use the term in a less strict way, to mean approximately the same thing as "culture" and therefore, the term can more broadly refer to any important and clearly defined human society.[citation needed] Still, even when used in this second sense, the word is often restricted to apply only to societies that have attained a particular level of advancement-especially the founding of cities.
The level of advancement of a civilization is often measured by its progress in agriculture, long-distance trade, occupational specialization, a special governing class and urbanism. Aside from these core elements, a civilization is often marked by any combination of a number of secondary elements, including a developed transportation system, writing, standardized measurement, currency, contractual and (tort-based) legal systems, characteristic art and architecture, mathematics, enhanced scientific understanding, metallurgy, political structures, and an astronomical understanding.
The Indus River (Sanskrit: सिन्धु Sindhu; Urdu: دریائے سندھ Daryā-e Sindh; Hindi: सिन्धु नदी Sindhu; Sindhi: سنڌو Sindhu; Punjabi: سندھ Sindh; Gujarati: સિંધુ નદી Sindhu; Pashto: اباسين Abāsin "Father of Rivers"; Persian: رود سند Rūd-e Sind; Arabic: السند Al-Sind; Tibetan: སེང་གེ།་གཙང་པོ Sênggê Zangbo "Lion River"; Greek: Ινδός Indós; Turki: Nilab) is a major river which flows through Pakistan. It has courses through western Tibet (in China) and Northern India.
Originating in the Tibetan plateau in the vicinity of Lake Mansarovar, the river runs a course through the Ladakh region of Jammu and Kashmir, Gilgit, Baltistan and flows through Pakistan in a southerly direction along the entire length of Pakistan to merge into the Arabian Sea near the port city of Karachi in Sindh. The total length of the river is 3,180 km (1,980 mi). It is Pakistan's longest river.
The river has a total drainage area exceeding 1,165,000 km2 (450,000 sq mi). Its estimated annual flow stands at around 207 km3 (50 cu mi), making it the twenty-first largest river in the world in terms of annual flow. Zanskar is its left bank tributary in Ladakh. In the plains, its left bank tributary is Chenab which itself has four major tributaries, namely, Jhelum, Ravi, Beas and Satluj. Its principal right bank tributaries are Shyok, Gilgit, Kabul, Gomal and Kurram. Beginning at the heights of the world in a spring and fed with glaciers and rivers in the Himalayas, the river supports ecosystems of temperate forests, plains and arid countryside.
