Featured Snippet: What is Indus Valley Civilization?

Indus Valley Civilization (IVC), जिसे Harappan Civilization भी कहते हैं, South Asia की पहली urban civilization थी. लगभग 2500 BCE से 1800 BCE के बीच यह civilization Indus River basin में flourishing थी. यह अपने advanced town planning, elaborate drainage system, और unique script के लिए जानी जाती है, जो इसे ancient Mesopotamia और Egypt की सभ्यताओं के बराबर खड़ा करती है.

IVC Chronology: Early, Mature, and Late Harappan

Competitive exams में IVC की chronology बहुत important है. इसे तीन phases में divide किया जाता है:

1. Early Harappan Phase (c. 3300 BCE – 2600 BCE): यह phase Pre-urban period था. इस समय villages develop हुए और farming settlements जैसे Mehrgarh (Pakistan) में कृषि और पशुपालन (farming and herding) के शुरुआती सबूत मिले हैं.
2. Mature Harappan Phase (c. 2600 BCE – 1900 BCE): यह IVC का peak period था. Advanced cities (जैसे Harappa और Mohenjo-daro) develop हुए. इस समय civilization अपने full bloom पर थी, with elaborate town planning, standardized weights, and extensive trade.
3. Late Harappan Phase (c. 1900 BCE – 1300 BCE): इस phase में major cities decline होने लगे. Population Indus valley से East की तरफ (Ganges basin) migrate होने लगी. Cemetery H culture और Painted Grey Ware culture इसी phase के बाद के developments हैं.

Indus Valley Town Planning and Urban Features

Harappan civilization की सबसे बड़ी विशेषता इसका extraordinary town planning था. It was far more advanced than contemporary civilizations in Mesopotamia and Egypt. Major features:

• Grid System: Cities को chessboard pattern पर बनाया गया था. Roads ( सड़कें) एक दूसरे को right angles (90 degrees) पर काटती थीं.
• Citadel and Lower Town: Most cities were divided into two parts: a smaller but higher area called the Citadel (for public buildings or administrative use) and a larger Lower Town (for residential purposes).
• Advanced Drainage System: Every house had a bathroom. Houses से waste water covered drains ( ढकी हुई नालियां) में जाता था. These main drains ran along the street and were covered with loose bricks/slabs for cleaning. This shows high priority on hygiene and public health.
• Standardized Bricks: All cities had buildings made of standardized burnt bricks ( पकी हुई ईंटें) with a fixed ratio (1:2:4 ratio).

Society, Economy, and Trade of Harappans

Archaeological evidence के आधार पर हम Harappan society और economy के बारे में कुछ conclusions निकाल सकते हैं:

Social Life:

• Social Classes: Large और small houses के existence से पता चलता है कि समाज में social stratification (सामाजिक वर्ग भेद) था. Scholars मानते हैं कि merchants (व्यापारी) upper class में थे.
• Dress and Ornaments: Spinning wheels (तकली) और needles से पता चलता है कि Harappans cotton और woolen clothes पहनते थे. Ornaments (गहने) gold, silver, copper, और precious stones से बने होते थे. Men और women दोनों ornaments पहनते थे.
• Recreation: Dancing Girl statue (Mohenjo-daro) indicates a love for dance. बच्चों के लिए terracotta toys, dice, और indoor games भी मिले हैं.

Economy:

• Agriculture: Main occupation agriculture था. Wheat, barley, pulses, cotton (दुनिया का सबसे पहला cotton cultivation), and rice (Lothal में evidence) produce किया जाता था. Farmers primarily relied on flood water, not canal irrigation.
• Animal Domestication: Zebu cattle, goats, dogs, buffaloes, and camels were domesticated. Horse remains Surkotada में मिले हैं, but their extensive use is debated. Iron (लोहा) का knowledge Harappans को नहीं था.
• Trade: Harappans का extensive internal trade था और external trade links Mesopotamia (Sumerians) and Dilmun (Bahrain) से थे. Seals का इस्तेमाल commercial purposes के लिए किया जाता था.

Religious Practices and Art of IVC

IVC के religious beliefs के बारे में कोई definitive evidence नहीं है, क्योंकि उनकी script deciphered नहीं हुई है. हालांकि, archaeological finds से कुछ inferences निकाले गए हैं:

• Mother Goddess: Numerous terracotta female figurines (मातृदेवी) मिले हैं. Scholars मानते हैं कि ये fertility cult या Mother Goddess worship को दर्शाते हैं.
• Pashupati Seal: Mohenjo-daro में मिली एक seal में एक seated figure को animals से घिरा हुआ दिखाया गया है. इसे Sir John Marshall ने Proto-Shiva या Pashupati (Lord of Animals) कहा.
• Nature Worship: Peepal tree, unicorn, fire altars (Kalibangan, Lothal) की पूजा होती थी. Temples (मंदिरों) का कोई structural evidence नहीं मिला है.
• Art and Sculpture: Bronze Dancing Girl statue और Priest-King sculpture (steatite) IVC art के masterpieces हैं. Seals पर unicorns, bulls, tigers जैसे animals के engravings common हैं.

Decline of Indus Valley Civilization Theories (Mains Topic)

IVC का decline एक mystery है. 1900 BCE के आस-पास यह civilization decay होने लगी. UPSC Mains में causes of decline पर questions frequently पूछे जाते हैं. Major theories हैं:

• Climate Change and Drought: Most accepted theory यह है कि climate change के कारण monsoon patterns change हुए. Ghaggar-Hakra river system सूख गया (aridity increased). इससे agriculture affected हुआ और cities sustain नहीं कर पाए. People migrated towards East (Ganges basin).
• Aryan Invasion Theory (Debunked): Sir Mortimer Wheeler ने यह theory दी थी कि light-skinned Aryans ने Indus cities पर invade करके dark-skinned Harappans को destroy कर दिया. Modern research (e.g., genetic studies, archaeological finds) ने इस theory को reject कर दिया है. No strong evidence of war or large-scale invasion found.
• Floods and Tectonic Shifts: Robert Raikes ने theory दी कि tectonic activity (earthquakes) के कारण Indus River के course में change आया, जिससे Mohenjo-daro जैसे cities floods में डूब गए.
• Resource Depletion: Increased population और over-exploitation of resources के कारण cities collapse हो गए.

Prelims Booster Points: Quick Revision

• Harappan script pictorial (pictographic) थी और अभी तक deciphered नहीं हुई है.
• Indus people को iron (लोहा) और sugarcane (गन्ना) की जानकारी नहीं थी.
• Dholavira IVC का एकमात्र city है जो three-part division (Citadel, Middle Town, Lower Town) में divided था.
• Lothal को IVC का 'Manchester' कहा जाता था due to its large dockyard and trade.
• Harappan seals most commonly unicorn animal को depict करते थे.

UPSC Mains Answer Writing Practice (150 Words)

Question: Discuss the factors responsible for the decline of the Indus Valley Civilization.

Answer: The decline of the Indus Valley Civilization around 1900 BCE remains debated, with multiple non-conclusive theories. Climate change and environmental degradation are widely accepted factors. A significant weakening of the monsoon led to aridification in the Ghaggar-Hakra region, drying up river systems vital for agriculture and forcing populations to migrate eastward towards the Ganges basin. Other theories include repeated catastrophic floods and tectonic shifts, which may have disrupted river courses, as suggested by evidence from Mohenjo-daro. The earlier 'Aryan Invasion Theory,' posited by Wheeler, has been largely debunked due to a lack of archaeological evidence of large-scale conflict. The decline was likely not a single event but a gradual process involving a combination of environmental stress and socio-economic changes, leading to the collapse of urban centers and dispersal of the Harappan population into smaller, post-urban settlements.

Frequently Asked Questions (FAQ) about IVC

1. Indus Valley Civilization को Harappan Civilization क्यों कहते हैं?

IVC को Harappan Civilization भी कहते हैं क्योंकि Harappa वह पहला site था जिसे 1921 में excavated किया गया था. चूंकि Harappa इस civilization का key site था, archaeologists ने इसे Harappan Civilization नाम दिया ताकि geographical context (Indus Valley) से परे भी sites को cover किया जा सके.

2. Indus Valley Civilization की key features क्या थीं?

प्रमुख विशेषताएं advanced town planning (grid system), elaborate drainage system, standardized bricks, centralized authority, और external trade links थीं. Great Bath of Mohenjo-daro और Dockyard of Lothal इसके प्रमुख उदाहरण हैं.

3. IVC के decline का मुख्य कारण क्या था?

IVC के decline का मुख्य कारण climate change और monsoon patterns का बदलना माना जाता है. इससे Ghaggar-Hakra river system सूख गया, जिससे agriculture difficult हो गया. Floods, earthquakes और resource depletion भी contributory factors थे, लेकिन Aryan invasion theory अब debunked हो चुकी है.

4. Indus people की religious beliefs क्या थीं?

Archaeological finds (Mother Goddess figurines, Pashupati seal) से पता चलता है कि वे Mother Goddess और Proto-Shiva (Pashupati) की पूजा करते थे. Nature worship (peepal tree, unicorn) भी prevalent थी. Temples (मंदिरों) का कोई evidence नहीं मिला है.
