Archaeological finds such as bricks, beads, and animal bones revealed a remarkably advanced civilisation that existed 4,600 years ago. People lived in well-planned cities with sturdy buildings and paved roads lined with drains, indicating a standard of life highly developed for its time. These discoveries first came to light during excavations at Harappa in 1921, headed by the archaeologist Dayaram Sahni. This ancient society is now known for its complex urban structures and its role as one of the oldest and most extensive civilisations in human history.
History is a multifaceted field of study that encompasses the systematic inquiry into past events through investigation and verification of evidence. The term originates from the Greek word 'historia,' meaning investigation or discovery, while its Sanskrit roots suggest the notion that 'it indeed happened this way.' Historically, early accounts of the past were often orally transmitted before being recorded in writing, highlighting a transition in how historical knowledge was preserved. Figures like Herodotus, known as the Father of History, and Kalhana, noted for his work on Indian history, played pivotal roles in establishing historical analysis as a rigorous discipline.
The Harappan civilisation, also referred to as the Indus Valley civilisation, flourished primarily along the banks of the Indus River and its tributaries. This strategic location supported key activities such as agriculture, animal husbandry, and trade, which were essential to the society's prosperity. It occupied a vast triangular area extending from Jammu in the north to the Narmada River in the south, and from western Balochistan to Uttar Pradesh in the east. This expansive civilisation thrived between 2600 BC and 1900 BC, at one point spanning a territory much larger than contemporary civilisations like ancient Egypt.
The civilisation was characterised by its highly organised urban layout, where cities featured a grid system with straight roads and sophisticated drainage networks. Houses and sewers were made of baked bricks, demonstrating a level of structural craftsmanship and public hygiene that rivalled or exceeded modern developments. Archaeologists use techniques such as excavation and the analysis of artefacts like seals, pottery, and skeletal remains to piece together the lifestyle and practices of these ancient people. These material remains serve as crucial evidence for understanding the social structure, economic activities, and technological prowess of the early urban dwellers.
