    1st-ever 3D map of Local Bubble’s magnetic fields

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Local Bubble

    Mains level: Not Much

    bubble

    Researchers have generated a 3D magnetic map of the giant cosmic cavity called Local Bubble that surrounds the solar system could reveal the universe’s secrets, including questions about the origins of stars.

    What is the Local Bubble?

    • The Local Bubble is a 1,000-light-year-wide cavity or a super-bubble.
    • It is a relative cavity in the interstellar medium (ISM) of the Orion Arm in the Milky Way.
    • Local Bubble is thought to have originated from supernovae roughly 14 million years ago. Supernova is a cosmic explosion occurring when stars meet their end.
    • Space is full of these super-bubbles that trigger the formation of new stars and planets and influence the overall shapes of galaxies.

    How are they formed?

    • Super-bubbles are comparable to holes in Swiss cheese. Supernova explosions blow holes in the cheese. New stars form around these holes.
    • However, mechanisms powering the formation and expansion of the Local Bubble are not well-understood.
    • Further, there is little information on how magnetic fields likely impact the bubble and local star formation.
    • Max Planck has provided information on the magnetic alignment of cosmic dust. This alignment can indicate the orientation of the magnetic field acting on the dust particles.

    Discretionary Haj Quota in India

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Haj Pilgrimage

    Mains level: Promoting religious tourism

    haj

    The Union Minister for Minority Affairs has done away with the discretionary Haj quota for pilgrims, in keeping with Prime Minister’s resolve to end VIP culture in the country.

    About Haj Pilgrimage

    • The holy Haj is an annual Islamic pilgrimage to Mecca, Saudi Arabia, the holiest city for Muslims.
    • It is considered to be a mandatory religious duty for all adult Muslims physically and financially capable of doing so.
    • The rites of pilgrimage are performed over five to six days, in Dhu al-Hijjah, the last month of the Islamic calendar.

    How is it managed?

    • For the Kingdom of Saudi Arabia, the pilgrimage poses a massive logistical challenge.
    • Housing, feeding and facilitating safe pilgrimages for millions of pilgrims who descend upon Mecca from across the world during a brief period of time is difficult, to say the least.
    • Thus, Saudi Arabia allots country-wise quotas which determine the total number of pilgrims who can make a journey from a particular country.
    • These quotas are broadly allotted on the basis of the number of Muslims a country houses. However, the quotas are also major diplomatic issues.
    • Every year, countries lobby Saudi Arabia for more slots. After a Covid-19-related lull, the pilgrimage will resume at its full scale in 2023.

    How India manages this?

    • India signed the Haj 2023 bilateral agreement with Saudi Arabia.
    • According to the agreement, a total of 1,75,025 Indian Haj pilgrims will be able to perform Haj, reportedly the highest in history.
    • This quota allotted to India is then further distributed by the Ministry of Minority Affairs and the Haj Committee of India (HCoI) to various stakeholders.
    • According to the 2018-22 policy document, 70 per cent of India’s total quota goes to the HCoI and 30 per cent goes to private operators.

    Distribution of Quotas

    • Out of the total number of slots with the HCoI, 500 are held under the Government discretionary quota whereas the rest are distributed to different states on the basis of their Muslim population.
    • A draw of lots is conducted in each state to determine who makes the journey in case the number of applicants exceed the number of slots available.

    What are the haj discretionary quotas?

    • The “Government discretionary quota” is further divided in two, 200 seats are with the Haj Committee itself and 300 are with people holding important offices at the Centre. These include,
    1. 100 with the President
    2. 75 with the Prime Minister
    3. 75 with the Vice President
    4. 50 with the Minister of Minority Affairs
    • As per the old policy, these seats could be allocated to individuals who applied for the pilgrimage through normal means but were unsuccessful in getting a slot for the pilgrimage.
    • This quota has now been abolished with these seats being added back to the general pool.

    From UPSC perspective, the following things are important:

    Prelims level: VSHORAD Missiles

    Mains level: Man portable missiles and their significance

    vshorad

    The Defence Acquisition Council (DAC) is set to procure the Very Short Range Air Defence System or VSHORAD (IR Homing) missile system.

    VSHORAD Missile System

    • Meant to kill low altitude aerial threats at short ranges, VSHORADS is a man portable Air Defence System (MANPAD).
    • It is designed and developed indigenously by DRDO’s Research Centre Imarat (RCI), Hyderabad, in collaboration with other DRDO laboratories and Indian Industry Partners.
    • The missile is propelled by a dual thrust solid motor—incorporates many novel technologies including miniaturised Reaction Control System (RCS) and integrated avionics, which were successfully proven during the tests conducted last year.
    • The DRDO has designed the missile and its launcher in a way to ensure easy portability.

    Unique features

    • Being man portable and lightweight compared to the other missile systems in the Army’s armoury, it can be deployed in the mountains close to the LAC at a short notice.
    • Others like the Akash Short Range Surface to Air Missile System are heavier with a theatre air defence umbrella.
    • They are perceived to be the best option for mountain warfare since they can be deployed quickly in rugged terrain.

    Significance of the missile

    • The development comes amid the ongoing military standoff with China at the LAC in eastern Ladakh and reports of air violations by China along the LAC last year.
    • India has been in talks with Russia since 2018 to procure the Igla-S air defence missiles at a cost of $1.5 billion under the VSHORAD programme in a bid to replace the Russian Igla-M systems.

    Ozone Hole filling up now

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Ozone Layer, Ozone Hole

    Mains level: Not Much

    ozone

    The ozone ‘hole’, once considered to be the gravest danger to planetary life, is now expected to be completely repaired by 2066, a scientific assessment has suggested.

    What is Ozone and Ozone Layer?

    ozone

    • An ozone molecule consists of three oxygen atoms instead of the usual two (the oxygen we breathe, O2, makes up 21% of the atmosphere).
    • It only exists in the atmosphere in trace quantities (less than 0.001%), but its effects are very important.
    • Ozone molecules are created by the interaction of ultra-violet (UV) radiation from the Sun with O2 molecules.
    • Because UV radiation is more intense at higher altitudes where the air is thinner, it is in the stratosphere where most of the ozone is produced, giving rise to what is called the ‘ozone layer’.
    • The ozone layer, containing over 90% of all atmospheric ozone, extends between about 10 and 40km altitude, peaking at about 25km in Stratosphere.

    Why need Ozone Layer?

    • The ozone layer is very important for life on Earth because it has the property of absorbing the most damaging form of UV radiation, UV-B radiation which has a wavelength of between 280 and 315 nanometres.
    • As UV radiation is absorbed by ozone in the stratosphere, it heats up the surrounding air to produce the stratospheric temperature inversion.

    What is Ozone Hole?

    • Each year for the past few decades during the Southern Hemisphere spring, chemical reactions involving chlorine and bromine cause ozone in the southern polar region to be destroyed rapidly and severely.
    • The Dobson Unit (DU) is the unit of measure for total ozone.
    • The chemicals involved ozone depletion are chlorofluorocarbons (CFCs for short), halons, and carbon tetrachloride.
    • They are used for a wide range of applications, including refrigeration, air conditioning, foam packaging, and making aerosol spray cans.
    • The ozone-depleted region is known as the “ozone hole”.

    Tropical Ozone Hole

    • According to the study, the ozone hole is located at altitudes of 10-25 km over the tropics.
    • This hole is about seven times larger than Antarctica, the study suggested.
    • It also appears across all seasons, unlike that of Antarctica, which is visible only in the spring.
    • The hole has become significant since the 1980s. But it was not discovered until this study.

    What caused an ozone hole in the tropics?

    • Studies suggested another mechanism of ozone depletion: Cosmic rays.
    • Chlorofluorocarbon’s (CFC) role in depleting the ozone layer is well-documented.
    • The tropical stratosphere recorded a low temperature of 190-200 Kelvin (K).
    • This can explain why the tropical ozone hole is constantly formed over the seasons.

    Try this PYQ

    Q.Consider the following statements:

    Chlorofluorocarbons, known as ozone-depleting substances are used:

    1. In the production of plastic foams
    2. In the production of tubeless tyres
    3. In cleaning certain electronic components
    4. As pressurizing agents in aerosol cans

    Which of the statements given above is/are correct?

    (a) 1, 2 and 3 only

    Who was Fatima Sheikh (1831-1900)?

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Fatima Sheikh

    Mains level: Pioneers of girl child education in India

    fatima

    Teaching pioneer Fatima Shaikh was recently honoured with a Google Doodle on her birthday.

    Fatima Sheikh

    • Fatima Sheikh was an educator and social reformer, who was a colleague of the social reformers Jyotirao Phule and Savitribai Phule.
    • She is widely considered to be India’s first Muslim woman teacher.
    • Fatima Sheikh was the sister of Mian Usman Sheikh, in whose house Jyotirao and Savitribai Phule took up residence.
    • One of the first Muslim women teachers of modern India, she started educating Bahujan children in Phules’ school.

    Association with Phules

    • Under pressure from upper castes, Jyotirao’s father evicted Savitribai and Jyotirao from the family home in the late 1840s.
    • With nowhere else to go, the Phules would find shelter at the house of Mian Usman Sheikh, where they would live till 1856.
    • As many from their own community abandoned them, Fatima Sheikh and her brother stood strongly with the Phules and the mission to educate girls and bahujans.
    • Sheikh met Savitribai Phule while both were enrolled at a teacher training institution run by Cynthia Farrar, an American missionary.
    • She taught at all five schools that the Phules went on to establish and she taught children of all religions and castes.
    • Sheikh took part in the founding of two schools in Mumbai (then Bombay) in 1851.

    Determined amidst opposition

    • In Pune, a conservative bastion of culture and tradition, the very act of trying to educate the underprivileged caused uproar.
    • It is said that the two women would often have stones and pieces of dung thrown at them while walking in the streets.
    • Fatima specifically is said to have borne the wrath of both upper-castes and radical orthodox sections.

    What is New Umbrella Entity (NUE) Network?

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: New Umbrella Entity (NUE)

    Mains level: Read the attached story


    umbrella

    The Reserve Bank of India (RBI) is said to have put on hold licensing of the New Umbrella Entity (NUE) network, a fintech institution planned as a rival to National Payments Corporation of India (NPCI).

    Why in news?

    • Six groupings, which included Facebook, Google, Amazon, Flipkart and others, had applied for NUE licences.

    What is New Umbrella Entity (NUE)?

    • NUE is an entity (under the Companies Act 2013) that will manage and operate the new payment system in the retail sector such as ATMs, POS, UPI etc.
    • NUEs will be set up for profit entities that will manage payments in the retail space.
    • These could offer a host of retail payment services, including setting up of ATMs, offering white-label, point of sale terminals, Aadhaar-based payments, remittance services, and develop newer payment methods.
    • They will also manage clearing and settlement systems that could be an alternative to the bank-promoted NPCI.
    • They will be allowed to charge fees for transactions (unlike the existing NPCI).
    • All NUEs will have to be interoperable with the National Payments Corporation of India (NPCI).

    Why need NUEs?

    • The NPCI is at the epicentre of the digital payments in the country.
    • RBI has introduced NUEs to end the so-called monopoly of NPCI.
    • The central bank also noted that during the pandemic, with people spending more time at home the usage of e-commerce has increased, and there’s been a significant rise in the incidence of internet fraud, cyber-crimes.

    If NPCI is doing its job well, then why NUE?

    • 48% of all electronic retail payments in the country pass through the NPCI infrastructure.
    • RBI’s concern stems from having the operations of so much of the country’s payment system concentrated in one entity.

    How will NUE aid Consumers?

    • With the introduction of NUEs, options for payment will increase for users.
    • This will result in more competition and eventually help boost transaction volumes for both platforms as e-commerce expands and reaches deeper into India’s unbanked hinterland.
    • In the World Bank’s most recent report on financial inclusion in 2017, some 190 million Indians did not have a bank account and more than half did not make or receive digital payments.
    • Customers who face frequent sever transaction due to server overload currently have few options.
    • In the new regime, they’ll be able to try the other platform.

    What about Data Safety?

    • Compliance as far as data safety and privacy is concerned holds good for all and sundry in the payments and banking space.
    • Every entity involved in payments and settlement have to follow the same set of rules.
    • RBI already have a new set of guidelines on “Regulation of Payment Aggregators and Payment Gateways” .
    • It ensures that neither the authorised Payment Aggregators (PAs) nor the merchants on-boarded by them can store customer card credentials within their database or server to avoid data breaches and potential abuse.

    Will NUEs replace NPCI?

    • NUEs will co-exist with NPCI to strengthen the payment infrastructure network.
    • A robust and resilient infrastructure is needed to ensure the government’s ambitious target of one billion digital transactions per day is achieved.
    • NUEs will not replace but complement NPCI in taking India’s digital payment success story to new heights.
    • By establishing a neutral and independent standards-setting body, we can make sure that the system as a whole in our country evolves in the best traditions of digital infrastructure adopted anywhere in the world.

    Living Root Bridges of Meghalaya

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Root bridges of Meghalaya

    Mains level: Not Much

    This newscard is an excerpt from the original article published in TH.

    Living Root Bridges

    root

    • A living root bridge is a type of simple suspension bridge formed of living plant roots by tree shaping.
    • They are common in the southern part of the Northeast Indian state of Meghalaya. Such a bridge is locally called jingkieng jri.
    • They are handmade from the aerial roots of rubber fig trees (Ficus elastic) by the Khasi and Jaintia peoples of the mountainous terrain along the southern part of the Shillong Plateau.
    • Most of the bridges grow on steep slopes of subtropical moist broadleaf forest between 50m and 1150m above sea level.

    Why is it so unique?

    • As long as the tree from which it is formed remains healthy, the roots in the bridge can naturally grow thick and strengthen.
    • New roots can grow throughout the tree’s life and must be pruned or manipulated to strengthen the bridge.
    • Once mature some bridges can have as many as 50 or more people crossing, and have a lifespan of up to 150 years.

    Superconductivity in Mercury

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Superconductivity in Mercury

    Mains level: Not Much

    mercury

    This newscard is an excerpt from the original article published in TH.

    What is a superconductor?

    • A superconductor is defined as a substance that offers no resistance to the electric current when it becomes colder than a critical temperature.
    • Some of the popular examples of superconductors are aluminium, magnesium diboride, niobium, copper oxide, yttrium barium and iron pnictides.

    How mercury becomes superconductor?

    • In 1911, Dutch physicist Heike Kamerlingh Onnes discovered superconductivity in mercury.
    • He found that at a very low temperature, called the threshold temperature, solid mercury offers no resistance to the flow of electric current.

    How is mercury capable of achieving superconductivity?

    Ans. Bardeen-Cooper-Schrieffer (BCS) theory

    • Scientists classified mercury as a conventional superconductor because its superconductivity could be explained by the concepts of Bardeen-Cooper-Schrieffer (BCS) theory.
    • While scientists have used the BCS theory to explain superconductivity in various materials, they have never fully understood how it operates in mercury — the oldest superconductor.
    • The researchers used state-of-the-art theoretical and computational approaches and found that all physical properties relevant for conventional superconductivity are anomalous in some respect in mercury.

    How BCS explains it?

    • In BCS superconductors, vibrational energy released by the grid of atoms encourages electrons to pair up, forming so-called Cooper pairs.
    • These Copper pairs can move like water in a stream, facing no resistance to their flow, below a threshold temperature.
    • By including certain factors that physicists had previously side-lined, the group’s calculations led to a clearer picture of how superconductivity emerges in mercury.
    • For example, when the researchers accounted for the relationship between an electron’s spin and momentum, they could explain why mercury has such a low threshold temperature (around –270°C).

    Coulomb repulsion and Mercury

    • Similarly, the group found that one electron in each pair in mercury occupied a higher energy level than the other.
    • This detail reportedly lowered the Coulomb repulsion (like charges repel) between them and nurtured superconductivity.
    • Thus, the group has explained how mercury becomes a superconductor below its threshold temperature.
    • Their methods and findings suggest that we could have missed similar anomalous effects in other materials, leading to previously undiscovered ones that can be exploited for new and better real-world applications.

    From UPSC perspective, the following things are important:

    Prelims level: Ottanthullal

    Mains level: NA

    ottanthullal

    A renowned folk artist has expressed his angst over the fading participation of students in Ottanthullal Artform.

    What is Ottanthullal?

    • Ottanthullal (or Thullal, in short) is recite-and-dance art-form of Kerala.
    • It was introduced in the 18th century by the famous Malayalam poet Kunchan Nambiar (1705 – 1770).
    • It is famous for its humour and social satire, and marked by its simplicity as opposed to more complex dance-forms like Kathakali and Koodiyattam.

    Unique features

    • Ottanthullal follows the classical principles of Natyasasthra (a treatise on art compiled in the 2nd century B.C.E).
    • It is enacted into three separate versions
    1. Ottanthullal
    2. Seethankan thullal
    3. Parayan thullal
    • The Ottanthullal is the most popular among the three varieties of Thullal.

    It is believed that Sagol Kangjei, the modern-day Polo game originated in Manipur.

    Sagol Kangjei

    • Modern polo is said to have originated from Sagol Kangjei, a sport indigenous to Manipur.

    What is Purchasing Managers Index (PMI)?

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: PMI

    Mains level: Not Much

    India’s Services sector reported a sharp growth with Services Purchasing Managers’ Index (PMI) surging to 58.5 last month from 56.4 in November 2022.

    Purchasing Managers’ Index (PMI)

    • PMI is an indicator of business activity — both in the manufacturing and services sectors.
    • It is a survey-based measure that asks the respondents about changes in their perception of some key business variables from the month before.
    • It is calculated separately for the manufacturing and services sectors and then a composite index is constructed.
    • The PMI is compiled by IHS Markit based on responses to questionnaires sent to purchasing managers in a panel of around 400 manufacturers.

    How is the PMI derived?

    • The PMI is derived from a series of qualitative questions.
    • Executives from a reasonably big sample, running into hundreds of firms, are asked whether key indicators such as output, new orders, business expectations and employment were stronger than the month before and are asked to rate them.

    How does one read the PMI?

    • A figure above 50 denotes expansion in business activity. Anything below 50 denotes contraction.
    • Higher the difference from this mid-point greater the expansion or contraction. The rate of expansion can also be judged by comparing the PMI with that of the previous month data.
    • If the figure is higher than the previous month’s then the economy is expanding at a faster rate.
    • If it is lower than the previous month then it is growing at a lower rate.

    What are its implications for the economy?

    • The PMI is usually released at the start of the month, much before most of the official data on industrial output, manufacturing and GDP growth becomes available.
    • It is, therefore, considered a good leading indicator of economic activity.
    • Economists consider the manufacturing growth measured by the PMI as a good indicator of industrial output, for which official statistics are released later.
    • Central banks of many countries also use the index to help make decisions on interest rates.

  • Climate Change Impact on India and World – International Reports, Key Observations, etc.

    What are Black Carbon Aerosols?

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Black Carbon Aerosols

    Mains level: Not Much

    black carbon

    Black carbon aerosols have indirectly affected the mass gain of the Tibetan Plateau glaciers by changing long-range water vapour transport from the South Asian monsoon region, a study has found.

    What are Black Carbon Aerosols?

    • Black Carbon (BC) aerosol, often called soot, is the dominant form of light absorbing particulate matter in the atmosphere.
    • They are emitted by incomplete combustion processes, both human (e.g., diesel engines) and natural (e.g., wildfire).
    • Its ability to absorb visible and infrared radiation means BC can heat the atmosphere and darken surfaces, specifically snow and ice.
    • These effects have important consequences on earth’s climate and climate change.
    • BC may also have adverse impacts on human health. Unlike long-lived greenhouse gases such as carbon dioxide, BC is removed from the atmosphere in 1-2 weeks, so its impacts tend to be more regional rather than global.

    Deposition over Himalayas

    • The South Asia region adjacent to the Tibetan Plateau has among the highest levels of black carbon emission in the world.
    • Many studies have emphasised black carbon aerosols from South Asia can be transported across the Himalayas to the inland region of the Tibetan Plateau.

    Impact on glaciers melting

    • Black carbon deposition in snow reduces the albedo of surfaces — a measure of how much of Sun’s radiations are reflected.
    • This accelerates the melting of glaciers and snow cover, thus changing the hydrological process and water resources in the region.
    • They heat up the middle and upper atmosphere, thus increasing the North-South temperature gradient.
    • As a result, precipitation in the central and the southern Tibetan Plateau decreases during the monsoon, especially in the southern Tibetan Plateau.
    • The decrease in precipitation further leads to a decrease of mass gain of glaciers.
    • From 2007 to 2016, the reduced mass gain by precipitation decrease accounted for 11% of the average glacier mass loss on the Tibetan Plateau and 22.1% in the Himalayas.

    Who was Savitribai Phule?

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Savitribhai Phule

    Mains level: Not Much

    phule

    Recently, 192nd birth anniversary of Savitribai Phule, w/o Jyotiba Phule (the pioneer of Satyashodhak Samaj) was celebrated.

    Who was Savitribai Phule?

    • A Dalit woman from the Mali community, Savitribai was born on January 3, 1831, in Maharashtra’s Naigaon village.
    • Married off at the age of 10, her husband Jyotirao Phule is said to have educated her at home.
    • Later, Jyotirao admitted Savitribai to a teachers’ training institution in Pune.
    • Throughout their life, the couple supported each other and in doing so, broke many social barriers.

    Pioneering first school for girls in India

    • At a time when it was considered unacceptable for women to even attain education, the couple went on to open a school for girls in Bhidewada, Pune, in 1848.
    • This became the country’s first girls’ school.

    Opposition to Phules’ schools

    • The Phules opened more such schools for girls, Shudras and Ati-Shudras (the backward castes and Dalits, respectively) in Pune.
    • This led to discontent among Indian nationalists like Bal Gangadhar Tilak.
    • They opposed the setting up of schools for girls and non-Brahmins, citing a “loss of nationality”, and believing not following the caste rules would mean a loss of nationality itself.
    • Savitribai herself faced great animosity from the upper castes, including instances of physical violence.
    • When serving as the headmistress of the first school in Bhide Wada, upper-caste men often pelted stones and threw mud and cow dung on her.

    Phule’s role as a social reformer, beyond education

    • Infanticide prevention: Along with Jyotirao, Savitribai started the Balhatya Pratibandhak Griha (‘Home for the Prevention of Infanticide’) for pregnant widows facing discrimination.
    • Child adoption: The Phules also adopted Yashwantrao, the child of a widow, whom they educated to become a doctor.
    • Reforms in marriages: Savitribai Phule also advocated inter-caste marriages, widow remarriage, and eradication of child marriage, sati and dowry systems, among other social issues.
    • Denouncing Brahmanical ritualism: As an extension, they started ‘Satyashodhak Marriage’ – a rejection of Brahmanical rituals where the marrying couple takes a pledge to promote education and equality.
    • Bubonic plague mitigation: Savitribai became involved in relief work during the 1896 famine in Maharashtra and the 1897 Bubonic plague. She herself contracted the disease while taking a sick child to the hospital, and breathed her last on March 10, 1897.

    Savitribai’s literary works

    • Savitribai Phule published her first collection of poems, called Kavya Phule (‘Poetry’s Blossoms’), at the age of 23 in 1854.
    • She published Bavan Kashi Subodh Ratnakar (‘The Ocean of Pure Gems’), in 1892.
    • Besides these works, Matushri Savitribai Phulenchi Bhashane va Gaani (Savitribai Phule’s speeches and songs’), and her letters to her husband have also been published.

    In news: Bhima-Koregaon Battle

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Battle of Bhima Koregaon

    Mains level: Not Much

    koregao

    The 205th anniversary of the Bhima-Koregaon battle was recently celebrated in all harmony at the Ranstambh (victory pillar) in Perne village in Pune.

    Battle of Bhima-Koregaon

    • The 1818 battle of Bhima-Koregaon, one of the last battles of the Third Anglo-Maratha War culminated in the Peshwa’s defeat.
    • It was fought on 1 January 1818 between the British East India Company (BEIC) and the Peshwa faction of the Maratha Confederacy, at Koregaon at the banks of River Bhima.
    • A 28,000-strong force led by Peshwa Baji Rao II while on their way to attack the company-held Pune were unexpectedly met by an 800-strong Company force of which 500 belonged to the Dalit community.
    • The battle was part of the Third Anglo Maratha war, a series of battles that culminated in the defeat of the Peshwa rule and subsequent rule of the BEIC in nearly all of Western, Central, and Southern India.

    Role of Mahar Community

    • Back in the seventeenth century, the community was particularly valued by the ruler Shivaji, under whom Maratha caste identities were far more fluid.
    • The value of the Mahars for military recruitment under Shivaji was noted by the social reformer Jyotirao Phule.
    • The Mahars were not only beneficiaries of the attempt at caste unity under Shivaji but were in fact valued for their martial skills, bravery, and loyalty.

    Mahars during Maratha Empire

    • The position occupied by the Mahars under Shivaji, however, was short-lived and under later Peshwa rulers, their status deteriorated.
    • The Peshwas were infamous for their Brahmin orthodoxy and their persecution of the untouchables.
    • The Mahars were forbidden to move about in public spaces and punished atrociously for disrespecting caste regulations.
    • Stories of Peshwa atrocities against the Mahars suggest that they were made to tie brooms behind their backs to wipe out their footprints and pots on their necks to collect their spit.

    Why is the battle significant?

    • The battle resulted in losses to the Maratha Empire, then under Peshwa rule, and control over most of western, central, and southern India by the British East India Company.
    • The battle has been seen as a symbol of Dalit pride because a large number of soldiers in the Company forces were the Mahar Dalits, the same oppressed community to which Babasaheb Ambedkar belonged.
    • After centuries of inhumane treatment, this battle was the first time that Mahars had been included in a battle in which they won.

    Dr. Ambedkar’s association

    • It was Babasaheb Ambedkar’s visit to the site on January 1, 1927, that revitalized the memory of the battle for the Dalit community.
    • He led to its commemoration in the form of a victory pillar, besides creating the discourse of Dalit valor against Peshwa ‘oppression’ of Dalits.
