Reformers who fought for equality
Why is B.R. Ambedkar remembered for social justice?
Ambedkar spent his life fighting caste discrimination, and he helped write equality into the Constitution. Social justice means fair treatment and equal chances for groups that were pushed down for centuries.
Who was he?
- Born: 14 April 1891, at Mhow near Indore.
- Constitution: he was elected Chairman of the Drafting Committee of the Constitution.
- Government: in 1947 he became independent India’s first Law Minister, in Nehru’s cabinet.
- Honour: he was given the Bharat Ratna after his death, in 1990.
What was the Poona Pact?
The British announced the Communal Award. It gave the “depressed classes” separate electorates. That means only voters of one group would choose that group’s members.
In September 1932, Ambedkar and Gandhi reached an understanding called the Poona Pact. Separate electorates were dropped. Instead, seats were reserved for the untouchables in legislatures and government jobs.
Is Ambedkar remembered only for the Constitution?
No. That is a common narrow view. He also led mass protests, like Mahad, and pushed for women’s rights through the Hindu Code Bill. Card 2 and card 9 cover both.

Sources: PIB, Ambedkar backgrounder, April 2023, PIB, Ambedkar’s life and journey.
What happened at Mahad in 1927?
At Mahad in March 1927, Ambedkar led about 5,000 people to a public water tank they had been kept away from. This protest is called the Mahad Satyagraha. A satyagraha is a peaceful protest that insists on what is right.
Why did the tank matter?
The tank was the Chavdar Tank in Mahad, in present-day Maharashtra. Since 1924, the Mahad municipality had allowed “untouchables” to take water from it. But the order was never carried out.
So the protest was about a simple right that existed only on paper. People still could not use public water.
What happened on those two days?
- 19 March 1927: a huge public meeting was held at Mahad, led by Ambedkar.
- 20 March 1927: about 5,000 men and women marched to the Chavdar Tank and washed their hands.
Upper-caste Hindus then “purified” the tank by pouring 108 pitchers of water into it. The municipality, under pressure, withdrew its order.
Did Ambedkar give up?
No. He launched a second satyagraha on 25 December 1927. On reaching Mahad, he learnt that a court case had been filed over the tank. He postponed the protest so as not to break the law.
He then fought the case himself. The Bombay High Court ruled for the Dalits on 17 March 1936.
Today, 20 March is observed as Social Empowerment Day to mark the Mahad Satyagraha.
Sources: PIB, Social Empowerment Day, 2003.
What value does Mother Teresa stand for?
Mother Teresa stands for selfless service: caring for people nobody else would look after, with no reward expected. She is already covered on this site under compassion. Here the focus is on service.
How did her work begin?
- 1931 to 1948: she taught at St. Mary’s High School in Calcutta, now Kolkata.
- 1948: she got permission to leave the school and work among the poorest people in the city’s slums.
- First step: she had no money, so she started an open-air school for slum children.
- 7 October 1950: the Holy See, the government of the Catholic Church, let her start her own order, the Missionaries of Charity.
- 1979: she was awarded the Nobel Peace Prize.
She later opened Nirmal Hriday in Kolkata, a home where dying people found on the streets could be cared for with dignity.
What is the misconception here?
Many people think the fame came first. It did not. She worked in the slums for about three decades before the 1979 Nobel Prize. That gap is why she is the classic example of service without seeking reward.

Courage in the freedom struggle
Why is Bhagat Singh a symbol of courage and sacrifice?
Bhagat Singh chose a bold protest, and he went to the gallows at 23. Sacrifice means giving up something precious, here life itself, for a larger cause.
What were the key events?
- Birth: 27 September 1907, at Banga village in Lyallpur district, now in Pakistan.
- 17 November 1928: Lala Lajpat Rai died of injuries. Police officer J.S. Scott had beaten him at a protest against the Simon Commission.
- 1928: Bhagat Singh, Chandra Shekhar Azad, Sukhdev and others founded the Hindustan Socialist Republican Association (HSRA) in Delhi.
- Revenge plan: Bhagat Singh, Rajguru, Sukhdev and Chandra Shekhar Azad meant to kill Scott. By mistaken identity, they shot another officer, Saunders, on 17 December 1928.
- 8 April 1929: Bhagat Singh and B.K. Dutt threw a bomb in the Central Legislative Assembly. It was a protest against two harsh Bills.
- 23 March 1931: Bhagat Singh, Rajguru and Sukhdev were hanged at Lahore Central Jail.
Why does the Assembly bomb show courage?
The aim was not to kill. Their leaflet said it was “to make the deaf hear”, meaning to force a careless government to listen.
The British had no clue who killed Saunders. In all probability, Bhagat Singh would never have been caught without the Assembly protest.
Was the trial fair?
No. The Governor-General set up a special tribunal for the Lahore conspiracy case. A special tribunal is a court created for one case. The accused were denied the right to appeal.
He was only 23 when he was hanged. He went to the gallows shouting “Inquilab Zindabad”, which means “Long live the revolution”. He is remembered as Shahid-e-Azam, the greatest of martyrs.
Sources: PIB, Shahid Bhagat Singh, 2007, NCERT Class 8, The Making of the National Movement.
What made Rani Lakshmibai a model of courage and leadership?
Rani Lakshmibai of Jhansi led her people against the British in 1857 and was defeated and killed in June 1858. Leadership here means standing in front when the cost is highest.
Why did she turn against the British?
After her husband died, she wanted the East India Company to accept her adopted son as heir to Jhansi. The Company refused.
What did she do in 1857?
In 1857, she joined the rebel sepoys and fought the British with Tantia Tope. Sepoys were Indian soldiers in the Company’s army.
She was defeated and killed in June 1858. Tantia Tope escaped and kept fighting a guerrilla war in central India.
Why was she unusual for her time?
Her story is still told in songs and poems, and exams test one of them.

Builders of modern India
How did Verghese Kurien turn a vision into results?
Kurien built farmer-owned dairy systems that helped India become the world’s largest milk producer. He is called the “Father of the White Revolution”. The White Revolution is the big rise in India’s milk production.
Which posts did he hold?
- NDDB: he was founder chairman of the National Dairy Development Board (NDDB) from 1965 to 1998.
- GCMMF: he was founder chairman of the Gujarat Co-operative Milk Marketing Federation from 1973 to 2006.
- Operation Flood: he led it.
- IRMA: he started the Institute of Rural Management at Anand in 1979.
A cooperative is a business owned and run by its own members. Here the members were village milk producers.
What was Operation Flood?
In the late 1960s, Kurien drew up a project called Operation Flood. It was launched in 1970. Its aim was “a flood of milk”, better rural incomes and reasonable prices for consumers.
- Phase I (1970-1980): it was paid for by selling skimmed milk powder and butter oil gifted by the European Economic Community (EEC).
- Phase II (1981-1985): milksheds grew from 18 to 136.
- Phase III (1985-1996): cooperatives got stronger infrastructure and veterinary services.
A National Milk Grid now links milk producers with buyers in over 700 towns and cities. It helps farmers get fair prices on a regular basis.
How big was the investment?
Operation Flood involved about Rs 1,700 crore, spread over 25 years.
What changed for India?
India went from a milk-deficient nation to the world’s largest milk producer. It has held that top place since 1998.
National Milk Day, 26 November, marks his birth anniversary. He was born on 26 November 1921, in Kozhikode, Kerala.
Sources: NDDB, Dr. Verghese Kurien, NDDB, Operation Flood, PIB, National Milk Day, 25 November 2024.
Why is E. Sreedharan linked with discipline and integrity?
Sreedharan is remembered for discipline and integrity in big public projects. He headed the Delhi Metro as its Managing Director, and that work earned him the nickname “Metro Man”. Integrity means being honest and doing what you promise, even when no one checks.
What was his role in the Konkan Railway?
- Before 1990: he was Member (Engineering) of the Railway Board and due to retire on 30 June 1990.
- New job: he was chosen to head the new Corporation as its Chairman and Managing Director.
- Budget: Railway Minister George Fernandes put the scheme in the February 1990 Railway Budget.
- 19 July 1990: Konkan Railway Corporation Limited was incorporated.
What was so hard about it?
The Konkan Railway is a 741 km line. It links Maharashtra, Goa and Karnataka. The route crosses rivers, deep valleys and steep hills.
The Corporation was first given just five years to build it. That time was later cut by six months. Sreedharan’s team finished the line in about seven years.
Why does 760 km also appear?
The early project plan gave a project length of 760 km. The Corporation now gives the line as 741 km. Use 741 km unless a question clearly means the original project plan.
How was he honoured?
He received the Padma Shri in 2001 and the Padma Vibhushan in 2008.
Is “on time” just a matter of luck?
No. It comes from planning and strict follow-up. That is the discipline exam questions point to.
Sources: Konkan Railway, home page, Konkan Railway, The Beginning, Padma Awards 2008 notification.
Why does the exam test the value, not the biography?
Exams usually describe an action and ask which value it shows. So you need the value behind each person, not their full life story.
An earlier lesson looked at Gandhi, Sardar Patel, Vinoba Bhave, Baba Amte and Nelson Mandela. This lesson adds six more names from the same part of the syllabus. The same rule applies to all of them.
What is the contrast trick?
Many of these people are remembered for a value that stands against a common failure.
- Sreedharan: he finished projects on time when delay was common.
- Kurien: he lifted up ordinary farmers when many schemes bypassed them.
- Ambedkar: he demanded equal access when caste rules shut people out.
The exam often tests this contrast, not just the name.
What does a typical question look like?
A question may say: “An officer builds a project on time, refuses shortcuts and keeps costs in check.” It will not name Sreedharan. You must spot the value: discipline and integrity.
Going deeper
What did the Hindu Code Bill change for women?
The Hindu Code Bill became four Acts in 1955-56 that gave Hindu women rights in marriage, divorce, property and guardianship. Ambedkar, as Law Minister, strongly supported it. So did Prime Minister Jawaharlal Nehru and many women’s groups.
What were the four Acts?
- Hindu Marriage Act: ended polygamy, set a marriage age for boys and girls, and gave Hindu women the right to divorce.
- Hindu Succession Act: gave Hindu women the right to inherit and hold property on the same terms as men.
- Hindu Minority and Guardianship Act: made a mother’s guardianship of her children equal to the father’s.
- Hindu Adoption and Maintenance Act: allowed adoption of a son or a daughter.
Polygamy means having more than one wife or husband at the same time.
Is the Special Marriage Act one of them?
No. That is a common trap. The Special Marriage Act was passed in 1954. It allowed divorce by mutual consent for people married in a civil ceremony. It is not one of the four Hindu Code Acts.
Why did Ambedkar resign?
In 1951, Ambedkar resigned as Law Minister. He cited differences on the Kashmir issue, foreign policy and Nehru’s approach to the Hindu Code Bill. So he left partly over the Hindu Code Bill.
The four Acts passed only in 1955-56, after he had left. His reform outlived his time in office.
What happened later?
A coparcener is a family member who gets a share of joint Hindu family property by birth. In 2005, an amendment made daughters coparceners too.
In Vineeta Sharma v. Rakesh Sharma (11 August 2020), the Supreme Court settled a doubt. A daughter is a coparcener whether she was born before or after the 2005 amendment.
Sources: NCERT, Gender and Women’s Empowerment, PIB, Ambedkar’s journey, Supreme Court, Vineeta Sharma v. Rakesh Sharma, 2020.
What do Bhagat Singh's writings show about him?
His writings show that he reasoned about his beliefs. His prison essay, “Why I Am an Atheist”, shows how he reasoned about his beliefs.
Why does this detail come up?
The exam sometimes tests it. It checks whether you know Bhagat Singh only as a symbol, or also know his ideas.
What is the common mix-up?
Not every revolutionary text was written by Bhagat Singh. “The Philosophy of the Bomb” is a good example. The NDA question in card 13 uses his name as a trap.
How do these figures help in the interview and essay?
They give you ready, real examples of values in action. They suit interview and essay answers.
What do interviewers ask?
A common question is which figure inspires your own idea of public service. Knowing several figures well helps more than knowing just one.
What is the follow-up question?
A good follow-up does not stop at the name. It asks for one specific action the person took. Then it asks how you would use that approach in a real office situation.
For example, you might name Ambedkar at Mahad. Then you could say you would make sure a public scheme reaches everyone, not just on paper.
Current affairs
How much milk does India produce now?
India produced 247.87 million tonnes of milk in 2024-25, the most of any country. These figures come from Basic Animal Husbandry Statistics (BAHS), released each year on National Milk Day, 26 November.
What are the latest numbers?
| Item | Figure |
|---|---|
| Milk output, 2023-24 | 239.30 million tonnes |
| Milk output, 2024-25 | 247.87 million tonnes |
| Growth in 2024-25 | 3.58 percent |
| Milk per person per day, 2014-15 | 319 grams |
| Milk per person per day, 2024-25 | 485 grams |
“Per capita availability” means how much milk is available for each person, on average, each day.
Which states lead?
The top five milk states in 2024-25 were Uttar Pradesh, Rajasthan, Madhya Pradesh, Gujarat and Maharashtra. Together they gave about 54 percent of India’s milk.
How does this link to Kurien?
India has been the largest milk producer since 1998. The cooperative system built under Operation Flood is the base of that lead.

Exam practice
Which past exam questions come from this lesson?
Here are two real questions from past papers, newest first.
CDS (II) 2025, General Knowledge, Q59.
The popular poem “Khoob ladi mardani woh to Jhansi wali rani thi” (Like a man she fought, she was the Rani of Jhansi) was written by:
(a) Mahadevi Varma
(b) Subhadra Kumari Chauhan
(c) Amrita Pritam
(d) Balamani Amma
The answer is (b), Subhadra Kumari Chauhan. Her Hindi poem “Jhansi Ki Rani” made this line famous.
NDA & NA (I) 2017, General Ability Test, Q128.
Who among the following is one of the authors of the book “Philosophy of the Bomb”?
(a) Bhagat Singh
(b) Jawaharlal Nehru
(c) Surya Sen
(d) Yashpal
The answer is (d), Yashpal. Bhagat Singh is the tempting wrong choice, which is exactly the trap from card 10.

Questions to think through
Why did the Mahad protesters need to march if the water order already existed?
The municipality’s 1924 order was never carried out. A right on paper means little until people can use it. The march made that gap visible.
Why is Bhagat Singh’s Assembly bomb seen as courage, not just violence?
In all probability, he would never have been caught for the Saunders killing. He still chose a public protest that led to his arrest and death.
Why does India still lead in milk decades after Operation Flood?
Operation Flood built village cooperatives and a National Milk Grid. Those systems still link farmers to buyers in hundreds of towns.
Why is the Special Marriage Act not part of the Hindu Code Bill?
It was passed in 1954 for civil marriages. The four Hindu Code Acts came in 1955-56 and dealt with Hindu law.
