Indian History, Polity & Current Affairs
Syllabus Unit: General Ability Test (GAT)
Why it matters
Chapter overview
Indian History, Polity & Current Affairs traces the country's story from the Indus Valley Civilization and medieval empires through the organized freedom struggle to Independence, then pivots to the structure of the Indian Constitution and government, and finally India's physical geography, economy and the ever-changing current affairs component — the single largest scoring opportunity in NDA's GAT for well-prepared candidates.
1Ancient & Medieval India
From the planned cities of the Indus Valley to the architectural grandeur of the Mughals, this span covers over 4,000 years of Indian civilization in the fixed sequence NDA tests it.
Learning Objectives
- Identify the key features of the Indus Valley Civilization (urban planning, script, major sites like Harappa and Mohenjo-daro).
- Sequence the major ancient dynasties — Mauryan and Gupta — and their notable rulers (Ashoka, Chandragupta II).
- Distinguish the major medieval dynasties — the Delhi Sultanate and Mughal Empire — and name their most significant rulers.
- Identify major religious/social movements of the ancient-medieval period (Buddhism, Jainism, Bhakti and Sufi movements).
Key Terms
Indian civilization's recorded story begins with the Indus Valley's silent, undeciphered cities and runs through a sequence of empires whose order NDA tests directly.
The Indus Valley Civilization
- Flourished c. 2500-1900 BCE along the Indus river; major sites Harappa, Mohenjo-daro, Dholavira, Lothal (a dockyard).
- Known for grid-pattern town planning, covered drainage systems, and the Great Bath at Mohenjo-daro.
- Its script remains undeciphered to this day, unlike its contemporaries in Mesopotamia and Egypt.
Major ancient dynasties
- Mauryan Empire (c. 321-185 BCE) — Chandragupta Maurya founded it; Ashoka expanded it, then turned to Buddhism after the Kalinga War.
- Gupta Empire (c. 320-550 CE) — called India's 'Golden Age' for advances in mathematics (zero), astronomy and literature (Kalidasa); Chandragupta II ('Vikramaditya') was its most celebrated ruler.
Medieval India: Delhi Sultanate to Mughals
- Delhi Sultanate (1206-1526) — 5 dynasties: Slave, Khilji, Tughlaq, Sayyid, Lodi; ended when Babur defeated Ibrahim Lodi at the First Battle of Panipat (1526).
- Mughal Empire (1526-1857) — Babur founded it; Akbar consolidated and reformed it (mansabdari, religious tolerance); Shah Jahan built the Taj Mahal; Aurangzeb was its last major expansionist ruler, after whom it declined.
Religious and social movements
Buddhism and Jainism arose in the 6th century BCE as reform movements against rigid Vedic ritualism; the medieval Bhakti movement (devotional worship, saints like Kabir, Mirabai) and the Sufi movement (Islamic mysticism, e.g. Nizamuddin Auliya) both promoted a personal, direct path to God across religious lines.
