partition of bengal

Central Idea

  • The recent controversy surrounding West Bengal’s ‘Foundation Day’ has brought attention to the partition of Bengal in 1947.
  • This event marked a significant chapter in the history of the state, leading to the creation of West Bengal and East Pakistan (later Bangladesh).

Partition of Bengal in 1947: An overview

  • Demand for a separate Muslim nation-state: The partition of Bengal was a consequence of the Muslim League’s demand for a separate nation-state for Indian Muslims.
  • Communal violence in Calcutta: The society became deeply divided along religious lines, leading to severe communal violence, particularly in Calcutta in August 1946.

Contours of East Pakistan’s Formation

  • Partition of India and Pakistan: In June 1947, it was decided to partition India into India and Pakistan. Punjab and Bengal, both with significant non-Muslim minorities, were also partitioned along religious lines.
  • Boundary Commission and the Radcliffe Line: A boundary commission, chaired by Sir Cyril Radcliffe, was established to demarcate separate districts with Hindu and Muslim majorities. The resulting boundary line is known as the Radcliffe Line.

Concentration of Muslims in East Pakistan

  • Demographic composition: Bengal had a Hindu majority in the western districts and a Muslim majority in the eastern districts.
  • Grouping under East Pakistan: The eastern districts were grouped together to form East Pakistan, similar to how Muslims were concentrated in the western districts of Punjab.

Precursor: Curzon’s Partition of Bengal in 1905

  • Historical context: Lord Curzon partitioned Bengal in 1905, aiming to break the unity of the Bengali-speaking population and create a separate province with a Muslim majority.
  • Reversal of partition: The partition of 1905 was withdrawn in 1911, restoring the linguistic unity of Bengal while separating Bihar and Orissa from Bengal.

Aftermath of the 1947 Partition

  • Communal violence and Gandhi’s influence: Bengal witnessed significant communal violence in 1946, particularly in Calcutta and Noakhali. However, the presence of Mahatma Gandhi helped prevent large-scale violence during the partition.
  • Migration and displacement: Unlike Punjab, migration in Bengal occurred gradually over time, resulting in a continuous trickle of people moving from East to West and vice versa. This led to a large refugee population and the need for rehabilitation and settlements.

Conclusion

  • The partition of Bengal in 1947 was a complex event with far-reaching consequences.
  • Understanding this historical context helps shed light on the impact it had on the population and the socio-economic landscape of West Bengal and todays Bangladesh.

President’s Rule

President’s Rule not an option in Manipur: MHA

Note4Students

From UPSC perspective, the following things are important :

Prelims level: President Rule, Article 356

Mains level: NA

Central Idea: Union Home Minister has said that imposition of President’s Rule in Manipur was not an option and the situation was soon returning to normal.

What is President Rule?

  • Article 356 of the Indian Constitution, commonly known as President’s Rule, empowers the President to impose central rule in a state where the constitutional machinery has broken down.
  • While initially intended for extraordinary circumstances, it has often been misused by central governments for political purposes.

Provisions of Article 356:

  • Imposition of President’s Rule: Article 356 allows the President to withdraw the executive and legislative powers of a state government when it cannot function in accordance with the Constitution.
  • Triggering factors: The President can invoke Article 356 based on a report from the Governor or suo motu if the constitutional machinery has broken down in the state.
  • Duration: It can be imposed for six months at a time, with a maximum duration of three years.
  • Parliamentary approval: Every six months, Parliament’s approval is required to continue the imposition of President’s Rule.

Historical Origins

  • Inspiration from the Government of India Act, 1935: Article 356 was inspired by Section 93 of this act, which allowed the Governor of a province to assume the powers of the government under certain circumstances.
  • Controlled democracy: The provision provided some autonomy to provincial governments while enabling British authorities to exercise ultimate power when necessary.

Political Misuse of Article 356

  • Early instances: During Congress dominance, Article 356 was used against governments of the Left and regional parties in states. Jawaharlal Nehru’s government utilized it six times until 1959, including to dislodge Kerala’s elected communist government.
  • Increasing misuse: In subsequent decades, Article 356 was used frequently against state governments by various central governments, including those led by Indira Gandhi and the Janata Party.

Landmark Judgment: S R Bommai Case

  • Landmark Supreme Court ruling: In the 1994 R. Bommai v. Union of India case, the Supreme Court provided detailed guidelines on the use of Article 356.
  • Specific instances for imposition: The court stated that President’s Rule can be invoked in cases of physical breakdown of the government or a ‘hung assembly.’
  • Curbing arbitrary use: The judgment emphasized the need to give the state government a chance to prove its majority or instances of violent breakdown before imposing President’s Rule.

Try this PYQ:

Which of the following are not necessarily the consequences of the proclamation of the President’s rule in a State?

  1. Dissolution of the State Legislative Assembly

What are Lab-Grown Diamonds (LGDs)?

Note4Students

From UPSC perspective, the following things are important :

Prelims level: Lab-Grown Diamond (LGD)

Mains level: NA

lab grown diamond ldg

Central Idea

  • During PM Modi’s state visit to the US, he presented First Lady Jill Biden with a 7.5-carat lab-grown diamond as a gift.
  • Lab-grown diamonds, also known as LGDs, have gained popularity in recent years due to their ethical and environmental advantages over mined diamonds.
The diamond, a gift for First Lady Jill Biden, was gifted in a papier mache box. “Known as kar-e-kalamdani, Kashmir’s exquisite papier mache involves sakthsazi or meticulous preparation of paper pulp and naqqashi, where skilled artisans paint elaborate designs,” a statement from the MEA said.

What is Lab-Grown Diamond (LGD)?

  • Lab-grown diamonds are diamonds created using technology that simulates the natural geological processes of diamond formation.
  • Unlike diamond simulants, such as Moissanite or Cubic Zirconia, LGDs possess the same chemical, physical, and optical properties as natural diamonds.

Ethical and Environmental Advantages

  • LGDs are considered socially and environmentally responsible alternatives to mined diamonds.
  • Their production avoids the socially exploitative aspects of diamond mining and reduces the environmental impact associated with traditional mining practices.

Characteristics of gifted diamond

  • Carat Weight: The diamond weighs 7.5 carats. Carat weight refers to the size and weight of the diamond, with one carat equal to 200 milligrams.
  • Origin: The diamond is created in a laboratory using advanced technology and does not come from natural diamond mining.
  • Certification: The diamond has been certified by the Gemological Lab, IGI (International Gemological Institute). Certification ensures that the diamond meets industry standards for quality and authenticity.
  • Cutting and Polishing: The diamond is expertly cut and polished to enhance its brilliance and visual appeal. The precise craftsmanship and attention to detail result in a well-cut and faceted diamond.

Methods of LGD Production

(A) High Pressure, High Temperature (HPHT) Method:

  • This common method involves subjecting a diamond seed, typically made of graphite, to extreme pressures and temperatures to transform it into a diamond.
  • HPHT requires heavy presses capable of generating immense pressure (up to 730,000 psi) and temperatures exceeding 1500 degrees Celsius.

(B) Chemical Vapor Deposition (CVD) and Explosive Formation:

  • CVD involves the deposition of carbon atoms onto a diamond seed using a gas mixture, resulting in the growth of a diamond layer.
  • Explosive formation, known as detonation nano-diamonds, utilizes explosive reactions to create tiny diamond particles.

Properties and Applications of LGDs

  • Optical Properties and Durability: LGDs possess similar optical dispersion to natural diamonds, giving them the characteristic sparkle. Their durability makes them suitable for industrial applications, such as cutters and tools.
  • Enhanced Properties and Industrial Uses: LGDs can have their properties enhanced for specific purposes, such as high thermal conductivity and negligible electrical conductivity. These properties make LGDs valuable for electronics, acting as heat spreaders for high-power laser diodes and transistors.

Impact on the Diamond Industry

(A) Sustainable Growth in the Jewellery Industry

  • As natural diamond reserves decline, LGDs are gradually replacing mined diamonds in the jewelry sector.
  • The production processes for LGDs, including cutting and polishing, align with established practices in the diamond industry.

(B) India’s Diamond Industry

  • The rise of LGDs is unlikely to significantly impact India’s diamond industry, which specializes in polishing and cutting diamonds.
  • India’s established diamond industry can continue to thrive while incorporating LGDs as part of its offerings.

Commercial LGD Production in India: InCent-LGD

  • In the Union Budget 23-24, a 5-year research grant was announced for an Indian Institute of Technology (IIT) with the aim of encouraging the development of LGD machinery, seeds, and recipes.
  • It would establish the India Centre for Lab Grown Diamond (InCent-LGD) at IIT Madras.
  • The primary aim of InCent-LGD is to provide technical assistance to domestic industries and entrepreneurs, fostering indigenous manufacturing of Chemical Vapour Deposition (CVD) and High Pressure and High Temperature (HPHT) systems.
  • The project seeks to expand the Lab-Grown Diamond (LGD) business by offering affordable technology to start-ups, creating employment opportunities, and boosting LGD exports.

Economic significance of LGDs

  • The Gems and Jewellery sector contributes approximately 9% to India’s total merchandise exports and plays a crucial role in the economy.
  • LGD have emerged as a notable technological development in the industry, finding applications not only in jewellery but also in sectors like computer chips, satellites, 5G networks, defense, optics, and thermal & medical industries.
  • The global LGD diamond market, valued at $1 billion in 2020, is expected to grow rapidly, reaching $5 billion by 2025 and surpassing $15 billion by 2035.

PM gifts Upanishads to Joe Bide

Note4Students

From UPSC perspective, the following things are important :

Prelims level: Ten Principal Upanishads

Mains level: Read the attached story

upanishad

Central Idea

  • PM Modi presented the US President Joe Biden with a number of gifts, including a first edition print of the book The Ten Principal Upanishads from 1937.

Ten Principal Upanishads

  • The Ten Principal Upanishads is translated from Sanskrit by Shri Purohit Swami, a scholar of Hindu scripture, and Irish poet WB Yeats.
  • It is considered to be one of the best translations of the Upanishads, some of the most important Hindu religious texts.
  • Written in the mid-1930s, the book was a product of Yeats’ desire to create a translation which is true to the original text while still being accessible for the layperson.

Two categories of Hindu scriptures

There are broadly two categories of Hindu sacred texts: Shruti (loosely translated as “the revealed”) and Smriti (“the remembered”).

[I] Shruti

  • The Shruti category is considered to be the most authoritative and consists of the four Vedas (Rig, Yajur, Sama and Atharva) and accompanying texts.
  • These include Brahmanas (ritual texts), Aranyakas (“forest” or “wilderness” texts), and Upanishads (philosophical texts).

[II] Smruti

  • The Smruti category of Hindu scriptures is less authoritative – in many ways they are considered to be derived from the first – but more popularly known.
  • These include the great epics of Ramayana and Mahabharata, Dharmashastras, Puranas and all other post-Vedic scriptures.

What are the Upanishads?

  • The Upanishads, also known as the Vedanta – as they signal the end of the total Veda – speculate about the ontological connection between humanity and the cosmos.
  • They serve as foundational texts in many traditions of Hindu theology and have hence attracted far more attention than the Vedas themselves.
  • Dated to roughly 800-500 BC, the Upanishads discuss concepts such as transmigration, which have today become central to Hindu tradition.
  • Upanishads signify texts that were traditionally transmitted in intimate, teacher-student settings, imparting profound knowledge and spiritual insights.

(A) Spiritual Essence

  • The Upanishads form the philosophical portion of the Vedic scriptures known as the Vedanta.
  • They explore the metaphysical and mystical aspects of existence, aiming to unravel the nature of reality, the self, and the ultimate truth.

(B) Origins

  • The Upanishads were composed between 800-500 BC, following the earlier Vedic texts.
  • Various sages, seers, and scholars authored the Upanishads, resulting in a rich diversity of philosophical perspectives.

(C) Themes and Subjects

  • The Upanishads delve into profound concepts, such as the nature of the self (atman), the ultimate reality (brahman) (NOT Brahmin), and the relationship between the two.
  • They explore metaphysical inquiries, the nature of existence, the concept of karma, the path to liberation (moksha), and the interconnectedness of all beings.

Key Upanishads and Teachings 

  • While there are over 200 Upanishads, a set of principal Upanishads is considered the most significant and influential.
  • There are ten main (or principal) Upanishads:
  1. Esha
  2. Kena
  3. Katha
  4. Prashna
  5. Mundaka
  6. Mandukya
  7. Taittiriya
  8. Aitareya
  9. Chandogya
  10. Brihadaranyaka

WB Yeats and his translation of Upanishads

(A) Who was WB Yeats? 

  • WB Yeats (1865-1939) was born in Ireland and is regarded as one of the most influential figures in modern English literature.
  • He was a key figure in the Irish Literary Revival, which sought to promote Irish culture, folklore, and independence.

(B) His Interest in the Upanishads

  • Yeats’ interest in Indian culture and philosophy predates his encounter with the Upanishads.
  • In 1885, he met Mohini Chatterjee, a prominent figure in Bengal’s Theosophical circles, who visited Dublin. This meeting sparked Yeats’ early engagement with Indian themes in his poetry.

(C) Friendship with Rabindranath Tagore:

  • Yeats developed a close friendship with Rabindranath Tagore, the renowned Indian poet, philosopher, and Nobel laureate.
  • In 1912, they met in London, where Tagore introduced Yeats to his translated work, including Gitanjali.

(D) Introduction to the Upanishads:

  • William Rothenstein, a photographer, sent Yeats the manuscripts of Tagore’s partial translation of the Upanishads.
  • Impressed by their spiritual depth and cultural significance, Yeats became intrigued by the Upanishads’ teachings.
  • Disappointed with the available English translations of the Upanishads, Yeats sought to create a translation that was both true to the original text and accessible to a wider audience.
  • He collaborated with Sanskrit scholar Shri Purohit Swami, who helped him translate the Upanishads with an emphasis on clarity and understanding.
