Indian History

1Indus Valley cities

The Indus Valley Civilization was a Bronze Age urban culture (c. 2600–1900 BCE). Its signature is planned cities — Harappa, Mohenjo-daro, Dholavira and Lothal — with advanced drainage and standardized baked bricks, not a single emperor's name on a coin.

Mohenjo-daro holds the Great Bath; Lothal is remembered as a dockyard site. Exam stems almost always test which city pairs with which feature, not a narrative of decline.

2Mauryas and Ashoka's turn

The Mauryan Empire was founded by Chandragupta Maurya in 322 BCE with guidance from Chanakya (Kautilya). The dynasty's examinable hinge is Ashoka after the Kalinga War (c. 261 BCE): the bloodshed led him to embrace Buddhism and to spread dhamma through rock and pillar edicts.

Keep the chain as cause and effect, not as three unrelated facts: Kalinga → renunciation of aggressive war → Buddhist dhamma and the edicts that James Prinsep later deciphered.

Figure. Mauryan hinge: Chandragupta founds; Ashoka after Kalinga turns to dhamma/Buddhism.

How the turn works

1. FoundingChandragupta, advised by Chanakya, establishes Mauryan rule in 322 BCE.
2. KalingaAshoka fights the Kalinga War around 261 BCE; the scale of killing reshapes his policy.
3. DhammaHe turns to Buddhism and broadcasts dhamma through rock and pillar edicts across the empire.

3Sources and Buddhist councils

Ancient Indian history is pinned by a small set of named sources: Megasthenes' Indica at the Mauryan court, Ashoka's edicts (deciphered by James Prinsep), and the Chinese pilgrims Fa-Hien and Hiuen Tsang describing Gupta and Harsha's India respectively.

Alongside those texts sit four major Buddhist councils — First at Rajgriha, Second at Vaishali, Third at Pataliputra under Ashoka, Fourth in Kashmir under Kanishka — tested as place-and-patron pairs.

4Mughals and the three Panipats

Babur established Mughal rule after the First Battle of Panipat (1526) against Ibrahim Lodi. The examinable succession is Babur, Humayun, Akbar, Jahangir, Shah Jahan (Taj Mahal), Aurangzeb — the BHAJSA line — with Akbar as the consolidator.

Panipat is three different wars, not one place-name reuse: 1526 Babur vs Ibrahim Lodi, 1556 Akbar's forces vs Hemu, 1761 Marathas vs Ahmad Shah Abdali. The last-two-digits mnemonic 26–56–61 keeps the years in order.

5Revolt of 1857

The Revolt of 1857 was India's first large-scale uprising against the British East India Company. It sparked at Meerut over the greased-cartridge grievance and spread as a wider challenge to Company power.

Its constitutional result matters as much as the spark: Company rule ended and power transferred to the British Crown in 1858. Treat spark and transfer as one story with two dates, not as two unrelated GK items.

Figure. 1857: Meerut spark → wider revolt → transfer from Company to Crown (1858).

From spark to Crown

1. SparkMeerut, 1857 — greased cartridges ignite the sepoys' revolt against the Company.
2. SpreadThe rising becomes the first large-scale challenge to Company authority across northern India.
3. TransferIn 1858, Company rule ends and the British Crown assumes direct control.

6Congress founded, Bengal partitioned

The Indian National Congress was founded in 1885 by A. O. Hume. The first session sat in Bombay and was presided over by W. C. Bonnerjee — founder and first president are two different names, and papers love swapping them.

Among early national milestones, the Partition of Bengal (1905) is the date that sits between founding and the later Gandhian mass movements; keep it as an administrative split that intensified politics, not as a Gandhian satyagraha.

Figure. Founder (Hume) ≠ first president (Bonnerjee). Bengal partition 1905 sits beside early nationalism.

7Gandhian mass movements

Gandhi's national campaigns are easiest to hold as keyword–year pairs: Champaran Satyagraha (1917), Kheda (1918), Non-Cooperation (1920–22), Civil Disobedience with the Dandi Salt March (1930), Quit India (1942).

Salt is the keyword for 1930 and for Civil Disobedience — not for Non-Cooperation (boycott, 1920) or Quit India ('Do or Die', 1942). The Dandi March began on 12 March 1930 from Sabarmati Ashram to Dandi to break the salt law and open Civil Disobedience.

Figure. Keyword–year spine: Champaran 1917 → Kheda 1918 → NCM 1920 → Dandi/Salt 1930 → Quit India 1942.

8Independence, 15 August 1947

India gained independence on 15 August 1947 under the Indian Independence Act, 1947. Jawaharlal Nehru became the first Prime Minister; Lord Mountbatten was the last Viceroy.

Hold the date, the Act, the first PM and the last Viceroy as one cluster — papers split them across four separate one-liners, and mixing Mountbatten with the first Governor-General role is a common slip if you only memorise a year.
