Prelims level: Muzhara Movement
Why in the News?
On March 19, the anniversary of the Muzhara movement is observed, marking a significant chapter in Punjab’s agrarian struggles.
About Muzhara Movement
- Muzharas were farmers who worked the land but had no ownership rights.
- They were part of a larger class of landless peasants in Punjab, facing oppressive feudal systems.
- The biswedars (landlords), who took one-third of the produce, controlled the land.
- This system led to economic exploitation, with a significant portion of the produce and profits going to the feudal landlords and, ultimately, the British colonial rulers.
- The muzharas were seeking ownership of the land they had tilled for generations, asserting their right to the land in opposition to both the feudal and colonial systems.
- In March 1949, when the biswedars tried to reclaim land from the muzharas, Kishangarh village became the epicentre of the struggle.
- A violent standoff between the muzharas and the Patiala police ensued, which resulted in the death of a police officer on March 17.
- The army intervened on March 19, leading to four muzharas being killed in the ensuing confrontation.
Other Contemporary Peasant’s Movements
|
Details |
| Champaran Satyagraha (1917) |
- Led by Mahatma Gandhi in Bihar against the tinkathia system, where peasants were forced to grow indigo on part of their land.
- Resulted in the Champaran Agrarian Act (1918), which abolished oppressive practices.
|
| Kheda Satyagraha (1918) |
- Organized in Gujarat after crop failures when the government refused to remit land revenue.
- Gandhi and Sardar Patel supported peasants in withholding revenue payments until demands were met.
|
| Bardoli Satyagraha (1928) |
- Led by Vallabhbhai Patel in Gujarat against a 30% hike in land revenue.
- The movement succeeded, and Patel earned the title “Sardar” for his leadership.
|
| Tebhaga Movement (1946-47) |
- Initiated by the Kisan Sabha in Bengal, demanding a two-thirds share of produce for tenants instead of the customary half.
- Despite being suppressed violently, it highlighted peasant rights.

Prelims level: Comptroller and Auditor General
Why in the News?
The Supreme Court has decided to examine a plea challenging the current process of appointing the Comptroller and Auditor General of India (CAG).
About Office of the Comptroller and Auditor General (CAG):
|
Details |
| Role and Importance |
- Established under Article 148 of the Indian Constitution.
- Ensures efficient and lawful use of public funds.
- Audits financial accounts of Consolidated Fund of India, state funds, and public sector undertakings.
- Acts as a watchdog over government financial expenditure.
- Plays a critical role in maintaining financial accountability in governance.
|
| Appointment and Term |
- Appointed by the President of India under a warrant.
- Serves a 6-year term or until the age of 65, whichever is earlier.
- Must take an oath to uphold the Constitution and perform duties impartially.
- Removal can only occur for misbehaviour or incapacity, through a special majority in both Houses of Parliament.
|
| Independence of the CAG |
- Independence from the government: Ineligible for any government office after leaving office.
- Salary and Expenses: Equal to a Supreme Court judge, with expenses charged to the Consolidated Fund of India.
- No Ministerial Representation: No minister can represent the CAG or assume responsibility for their actions.
|
Issues with the Appointment of the CAG
The current process for appointing the CAG is seen as problematic due to the centralized control by the Union government.
- The CAG is appointed by the President on the advice of the government, raising concerns about potential executive influence over a key independent body.
- Critics argue that this process compromises the CAG’s independence and calls for a neutral selection committee involving the Prime Minister, Leader of the Opposition, and Chief Justice of India.
- This would ensure that the CAG is appointed transparently and impartially, free from political interference.
- Historically, the lack of clear guidelines in Article 148 regarding the CAG’s appointment has allowed executive interference, much like the early years of judicial appointments.
Supreme Court interventions have already reformed appointment processes for bodies like the Election Commission and Central Vigilance Commission, and similar reforms for the CAG are necessary to protect its autonomy.
[UPSC 2012] In India, other than ensuring that public funds are used efficiently and for intended purpose, what is the importance of the office of the Comptroller and Auditor General (CAG)?
1. CAG exercises exchequer control on behalf of the Parliament when the President of India declares national emergency/financial emergency.

Prelims level: Miller-Urey Hypothesis
Why in the News?
A recent study led by Stanford University chemist Richard Zare has introduced a novel perspective on the origins of life on Earth, providing an alternative to the well-known Miller-Urey hypothesis.
About the Miller-Urey Hypothesis
- The Miller-Urey hypothesis emerged from an experiment conducted in 1952 by chemists Stanley Miller and Harold Urey.
- It sought to simulate the conditions of early Earth to understand how life could have originated.
- They used a mixture of water, methane, ammonia, and hydrogen, gases believed to be present in the early Earth’s atmosphere.
- The setup also included an electric spark to simulate lightning, which they hypothesized could have played a role in the formation of organic compounds.
- Results: The experiment successfully demonstrated that organic molecules, like amino acids, essential for life, could form when an electrical spark (simulating lightning) was applied to the gas mixture.
- Impact and Debate:
- The experiment was a landmark in understanding life’s chemical origins.
- However, over time, critics argued that real lightning would have been rare and mostly occurred over open ocean, where organic compounds would have been quickly dispersed.
- This led to the questioning of lightning as the primary trigger for life’s origins.
Life on Earth and the Role of ‘Microlightning’ in Water Droplets
- The Stanford study shows that when water droplets divide, they develop opposing electrical charges—larger droplets become positively charged, and smaller droplets become negatively charged.
- When these oppositely charged droplets come close together, tiny sparks (termed micro-lightning) can leap between them, mimicking the electrical phenomena that occur in thunderstorms.
- Experimental Evidence:
- In the experiment, when water sprays were mixed with nitrogen, methane, carbon dioxide, and ammonia, they produced organic compounds like glycine and uracil, similar to those in the Miller-Urey experiment.
- Microlightning from water sprays can therefore generate organic compounds, providing a plausible and common natural process for the origin of life.
- These microlightning events could have been far more common and accessible than lightning strikes, offering an alternative mechanism for the generation of life-building organic molecules.
PYQ:
[UPSC 2012] Which one of the following sets of elements was primarily responsible for the origin of life on the Earth?

Why in the News?
In a groundbreaking achievement, Italian researchers have successfully transformed light into a supersolid for the first time in history.
About Supersolid
- A supersolid is a rare state of matter that behaves like both a solid and a liquid at the same time.
- While it maintains a rigid structure, similar to a solid, it can also flow like a liquid without any internal friction.
- How was a supersolid created?
- Researchers made a supersolid by combining light and matter.
- They used polaritons (a mix of light and particle pairs called excitons) to create this new state of matter.
- When these polaritons reach their lowest energy, they form the supersolid that behaves like both a solid and a liquid.
- Features of a Supersolid:
- Dual Nature: A supersolid is solid in structure but can also flow like a liquid.
- Quantum Coherence: The particles inside a supersolid work together in a special way because of quantum mechanics, creating unique behaviors.
- Zero Viscosity: It moves without any resistance, just like a superfluid, meaning it can flow freely even though it’s solid.
- Temperature Dependency: Supersolids only form at extremely low temperatures (close to absolute zero, or -273.15°C).
Applications of Supersolids
- Quantum Computing: Supersolids could help improve the performance of quantum computers, making them more stable.
- Superconductors: They might be used to create materials that allow zero-resistance electricity, improving energy transmission.
- Frictionless Lubricants: Supersolids could lead to frictionless lubricants, making machinery work more efficiently and last longer.
- Fundamental Physics: Studying supersolids helps us understand quantum physics and how particles behave under extreme conditions.
- Material Science: Supersolids could help create new materials for advanced technology, including computers, sensors, and energy storage.

- Under Article 342, the President notifies STs for each State/UT after consultation with the Governor, and modifications can only be made by Parliament through legislation.
- Currently, 705 STs are notified across 30 States/UTs, comprising 8.6% of India’s population (2011 Census).
- They are mainly concentrated in Central India (Madhya Pradesh, Chhattisgarh, Jharkhand, etc.) and the North-East.
Existing Criteria for ST Classification (Lokur Committee, 1965)
- The Lokur Committee (1965) laid down 5 key criteria for classifying STs:
- Primitive Traits
- Distinctive Culture
- Geographical Isolation
- Shyness of Contact with the Community at Large
- Backwardness
- Criticisms of Existing Criteria:
- Termed obsolete, condescending, and colonial by scholars.
- Many communities today do not fully meet all criteria.
- Fails to reflect regional diversity, historical coexistence, and social changes.
- Overly dependent on a binary view of ‘tribe’ vs. ‘non-tribe’, leading to inclusion-exclusion conflicts (e.g., Meitei ST demand in Manipur).
Proposal for a ‘Spectrum of Tribalness’
Recent academic and policy discussions (e.g., at the Indian Anthropology Congress) advocate for a paradigm shift:
- Replace binary classification with a “spectrum of tribalness” or matrix of indicators.
- Use a broader set of 100-150 indicators, including:
- Marriage, kinship systems, language, rituals, governance structures, cultural materiality (e.g., headgear, weaponry) etc.
- Assign weightage to each indicator to determine the degree of tribalness.
PYQ:
[2024] Consider the following statements:
1. It is the Governor of the State who recognizes and declares any community of that State as a Scheduled Tribe.
2. A community declared as a Scheduled Tribe in a State need not be so in another State.
