📖 The Indus Valley Civilisation (c. 2500-1750 BCE)

One of the world's oldest urban civilisations, spread across present-day Pakistan and north-west India. Known for planned cities with grid layouts, covered drainage systems, and standardised weights and measures — evidence of strong civic administration. Major sites include Harappa, Mohenjo-daro, Dholavira, and Lothal (a dockyard site). The script remains undeciphered to this day, which is why much about the civilisation's political and religious life is inferred rather than confirmed.

🕉️ The Vedic Age (c. 1500-600 BCE)

Divided into the Early Vedic (Rig Vedic) period, largely pastoral and tribal, and the Later Vedic period, which saw the rise of agriculture, iron tools, varna-based social stratification, and larger political units (janapadas). The four Vedas, Upanishads, and early philosophical thought all emerge from this era.

🌱 Rise of Mahajanapadas & New Religions (c. 600 BCE)

Sixteen major states (Mahajanapadas) emerged in northern India, with Magadha eventually dominating. This period also saw the rise of Buddhism (founded by Siddhartha Gautama) and Jainism (associated with Mahavira) — both reacting against Vedic ritualism and rigid social hierarchy.

👑 The Mauryan Empire (322-185 BCE)

Founded by Chandragupta Maurya with the guidance of Chanakya (Kautilya), author of the Arthashastra. Reached its peak under Ashoka, who, after the bloody Kalinga War, embraced Buddhism and propagated Dhamma (moral policy) through edicts inscribed on rocks and pillars across the empire.

🏛️ The Gupta Empire (c. 320-550 CE) — the "Golden Age"

Often called India's classical "Golden Age" for its achievements in science, mathematics (the concept of zero, decimal system), astronomy (Aryabhata), art, and Sanskrit literature (Kalidasa). Key rulers include Chandragupta I, Samudragupta (known for military conquests, recorded in the Allahabad Prashasti), and Chandragupta II (Vikramaditya).

💡 Key Facts

The Indus Valley script remains undeciphered to date.
Lothal (Gujarat) was a major dockyard of the Indus Valley Civilisation.
Ashoka's edicts were mostly written in Prakrit, using the Brahmi script.
Aryabhata, a Gupta-era mathematician, is credited with early work on the concept of zero and the decimal system.

🔖 60-Second Revision

IVC (c. 2500-1750 BCE): planned cities, undeciphered script, no clear evidence of kingship.
Vedic Age: Early (pastoral) → Later (agrarian, varna system).
600 BCE: Mahajanapadas rise; Buddhism & Jainism emerge as reform movements.
Maurya (322-185 BCE): Chandragupta → Ashoka (Kalinga War → Dhamma).
Gupta (320-550 CE): Golden Age — science, math, Sanskrit literature.
