Every year, Modern Indian History contributes roughly 8 to 12 questions in UPSC Prelims. That means getting these facts right can be the difference between clearing the cutoff and missing it by two marks. I have spent years tracking question patterns, and in this piece, I am sharing the facts that carry the highest probability of appearing in your 2026 paper.
Where This Topic Sits in the UPSC Syllabus
Modern Indian History falls under General Studies in both Prelims and Mains. For Prelims, the syllabus mentions “History of India and Indian National Movement.” For Mains, it sits under GS Paper I — “Modern Indian History from about the middle of the eighteenth century until the present.”
| Exam Stage | Paper | Syllabus Section |
|---|---|---|
| Prelims | General Studies | History of India and Indian National Movement |
| Mains | GS-I | Modern Indian History — significant events, personalities, issues |
UPSC has consistently asked factual recall questions from this section. Movements, their timelines, associated leaders, and colonial-era legislations dominate the question pool.
Early Colonial Period — Facts 1 to 10
The Battle of Plassey (1757) established British political power in Bengal. Robert Clive defeated Siraj-ud-Daulah with the help of Mir Jafar. The Regulating Act of 1773 was the first step by the British Parliament to control the East India Company. It created the post of Governor-General of Bengal — Warren Hastings was the first.
The Permanent Settlement (1793) introduced by Lord Cornwallis fixed land revenue in Bengal, Bihar, and Odisha. It created the Zamindari system. The Ryotwari System was introduced by Thomas Munro in Madras, where the government dealt directly with cultivators. The Doctrine of Lapse, used aggressively by Lord Dalhousie, annexed Satara, Jhansi, and Nagpur among others. The Charter Act of 1833 made the Governor-General of Bengal the Governor-General of India. Lord William Bentinck was the first to hold this title.
The Revolt of 1857 started in Meerut on 10 May 1857. Mangal Pandey’s incident at Barrackpore preceded it. Bahadur Shah Zafar was declared the nominal leader. The revolt failed due to lack of coordination, limited geographical spread, and absence of a unified leadership.
Reform Movements and Socio-Religious Facts — Facts 11 to 20
Raja Ram Mohan Roy founded the Brahmo Samaj in 1828. He campaigned against Sati, which was abolished by Lord William Bentinck through Regulation XVII in 1829. Arya Samaj was founded by Swami Dayananda Saraswati in 1875 in Bombay. His motto was “Go back to the Vedas.”
The Aligarh Movement led by Sir Syed Ahmad Khan promoted modern education among Muslims. Jyotirao Phule founded the Satyashodhak Samaj in 1873 to fight caste discrimination. The Theosophical Society was promoted in India by Annie Besant, who also started the Home Rule League in 1916. Swami Vivekananda represented Hinduism at the Parliament of Religions in Chicago (1893). Ishwar Chandra Vidyasagar championed widow remarriage, leading to the Widow Remarriage Act of 1856.
Indian National Movement Phase I — Facts 21 to 30
The Indian National Congress was founded in 1885 by A.O. Hume. The first session was held in Bombay under W.C. Bonnerjee. The early phase (1885–1905) is called the Moderate Phase. Leaders like Dadabhai Naoroji, Gopal Krishna Gokhale, and Pherozeshah Mehta used petitions and prayers.
The Partition of Bengal (1905) by Lord Curzon triggered the Swadeshi Movement. This was the first mass movement. Bal Gangadhar Tilak declared, “Swaraj is my birthright and I shall have it.” The Surat Split (1907) divided Congress into Moderates and Extremists. The Morley-Minto Reforms (1909) introduced separate electorates for Muslims — a decision that had long-lasting consequences. The Lucknow Pact (1916) brought Congress and Muslim League together temporarily.
Gandhian Era — Facts 31 to 42
Gandhi returned to India in 1915. His first Satyagraha in India was the Champaran Satyagraha (1917) against the indigo planters. The Kheda Satyagraha (1918) was about land revenue. The Rowlatt Act (1919) allowed detention without trial. Gandhi called it a “Black Act” and launched a nationwide hartal.
The Jallianwala Bagh Massacre (13 April 1919) was ordered by General Dyer in Amritsar. Rabindranath Tagore renounced his knighthood in protest. The Non-Cooperation Movement (1920–22) was suspended after the Chauri Chaura incident where a mob set fire to a police station. The Simon Commission (1927) was boycotted because it had no Indian member.
The Dandi March (12 March 1930) launched the Civil Disobedience Movement. Gandhi walked 241 miles from Sabarmati to Dandi to break the salt law. The Gandhi-Irwin Pact (1931) ended the movement temporarily. The Round Table Conferences — three held between 1930 and 1932 — Gandhi attended only the second. The Communal Award (1932) by Ramsay MacDonald gave separate electorates to Depressed Classes. Gandhi opposed it. The Poona Pact between Gandhi and Ambedkar replaced separate electorates with reserved seats.
The Government of India Act 1935 introduced provincial autonomy and proposed an All-India Federation. It is the longest act ever passed by the British Parliament. The Quit India Movement (8 August 1942) had the slogan “Do or Die.” Leaders were arrested immediately, and the movement became leaderless. The INA trials (1945) at Red Fort became a rallying point for national unity.
Revolutionary Movements and Other Key Facts — Facts 43 to 50
Subhas Chandra Bose formed the Azad Hind Fauj (INA) and gave the call “Delhi Chalo.” The Kakori Conspiracy Case (1925) involved Ram Prasad Bismil and Ashfaqullah Khan. Bhagat Singh, Rajguru, and Sukhdev were hanged on 23 March 1931 in the Lahore Conspiracy Case. The Cripps Mission (1942) was rejected — Gandhi called it a “post-dated cheque on a crashing bank.”
The Cabinet Mission Plan (1946) proposed a three-tier structure and rejected the demand for Pakistan. The Mountbatten Plan (3 June 1947) announced the partition of India. The Indian Independence Act 1947 was passed by British Parliament on 18 July 1947. India became independent on 15 August 1947. The Constituent Assembly, already formed in 1946, became the sovereign body of free India.
Key Points to Remember for UPSC
- Doctrine of Lapse was used by Dalhousie — remember Satara (first annexed), Jhansi, and Nagpur.
- The Moderate-Extremist split happened at the Surat Session (1907), and reunification happened at Lucknow (1916).
- Gandhi’s three major movements in order: Non-Cooperation (1920), Civil Disobedience (1930), Quit India (1942).
- The Poona Pact replaced separate electorates with reserved seats — this distinction is frequently tested.
- Government of India Act 1935 forms the structural basis of the Indian Constitution.
- The Cabinet Mission rejected Pakistan but proposed grouping of provinces — this nuance matters in Prelims.
- Match each Viceroy to their key reform or act — Curzon (Bengal Partition), Ripon (Local Self-Government), Dalhousie (Doctrine of Lapse).
These 50 facts cover the themes that UPSC has tested repeatedly across the last two decades. I recommend you make flashcards for each fact — write the event on one side and the year, person, and one-line significance on the other. Revise them weekly until your exam date. Consistent revision of high-probability facts is the most efficient way to secure those 8 to 12 marks that Modern History offers every year.
