Indus Valley Civilization is one of the earliest and most advanced settlements during the Bronze era in the Indian subcontinent. It is one of the three early civilisations subsequent Mesopotamian and Ancient Egyptian Civilisation with about five million citizens.

From 3300 BCE to 1300 BCE, it evolved from small village clusters to metropolitan cities stretching over 900 miles. The excavated sites are in parts of Sindh, Punjab and Balochistan province in Pakistan and parts of North-Western India.

The identification of Harappa in 1921 led to the discovery of 1056 cities in present-day Pakistan and India. Thus, also known as the Harappan Civilisation for its initial discovery and prominence. Harappa and Mohenjodaro are the most important cities with advanced inventions, administration, and planning, considering other settlements at the time.

Historical Timeline of Indus Valley Civilization

The Indus Valley Civilisation consists of three phases—The Early Harappan (3300BCE-2600BCE), Mature Harappan(2600BCE-1900BCE) and Late Harappan (1900BCE-1300BCE).

The civilization originated from migration to Mehrgarh, a Neolithic site along the Indus river in Kacchi plain in Pakistan. It is one of the most valuable sites belonging to the Pre-Harappan period marked by agricultural development. The Early Harappan which originated in 3300BCE also known for the earliest known evidence of the Indus script. They had a centralized authoritarian system with trade networks profiting from raw materials and crops. Animal domestication of water buffalo and cultivation of crops such as cotton and dates begun during this time. Many started migrating from villages to more developed cities in hopes of better living. The Mature Harappan period marks the inception of flood-supported farming by taming the tributaries of the Indus river. The people not equipped with irrigation facilities and relied on the seasonal monsoon.

Architecture and Town Planning

The Harappan Civilisation was particular on a well-planned, luxurious and hygienic society. The area splits into the lower public area and upper acropolis area, both similar in layout. The roads formed a linear grid-iron street layout that intersects at the central fortress. The mound-shaped citadel raised to 6m height was a refuge against external attack. The shore is about 40ft above water level as it is an easily flooded area. An outer defensive wall made of baked bricks acts as a dam against floods and invasion. The houses were in a rigid block arrangement around a central courtyard with all amenities. Its orientation aligned with the rising sun/ moon and made use of the traditional sun-path method. The houses also used baked bricks and about 1-2 floors. The wall was 70cm thick and 3m in height.

The plumbing and drainage system running along the streets separate the rows of multi-storied homes, providing clean water to all. Public baths and private wells were abundant in the settlement.

The main reason for the sudden end of civilization is unknown. Also, archaeologists came up with theories of possibilities from the pieces of evidence.

Some speculate climate change or floods as the planning, although efficient, lacked means to resist floods. While others believe the cause could be the drying up of the Saraswati River that happened in 1900BCE. Evidence of earthquake damage in Dholavira indicates another causation. The invasion of Aryans in the later periods greatly impacted the peaceful regime of the place.

Although they ended drastically, the advancement in science and technology unbelievable compared to other settlements.
