🔆 RISE OF MILITANT NATIONALISM (EXTREMISM)
📍 Background
🟢 By the dawn of the 20th century, militant nationalists emerged within the Indian national movement.
🟢 Important leaders included Bal Gangadhar Tilak, Aurobindo Ghosh, Bipin Chandra Pal, Lala Lajpat Rai, Raj Narain Bose, Ashwini Kumar Datta and Vishnu Shastri Chiplunkar.
🟢 They rejected excessive faith in British rule and emphasised Swaraj, mass participation, direct political action and self-sacrifice.
📍 Factors Behind the Rise of Extremists
🟢 Loss of Faith in British Rule: Economic drain, British indifference towards Indian demands and the failure of constitutional methods weakened faith in moderate politics.
🟢 Famine & Plague: The 1896–97 famine and bubonic plague exposed the inadequacy and insensitive nature of British relief measures, generating widespread resentment.
🟢 Political Despondency: Limited achievements of the Moderates, along with measures such as the arrest of Tilak and the Sedition Act, created frustration among nationalists.
🟢 Curzon’s Reactionary Policies: Policies such as the Calcutta Corporation Act (1899), Indian Universities Act (1904), enforcement of the Sedition Act, Official Secrets Act (1904) and ultimately the Partition of Bengal (1905) intensified nationalist opposition.
🟢 International Events: The rise of Japan and the defeat of European powers, particularly Russia by Japan and Italy by Ethiopia, shattered the myth of European invincibility.
🟢 Impact of Reform Movements: Movements such as Arya Samaj and thinkers such as Swami Vivekananda encouraged self-respect, national consciousness and social rejuvenation.
🟢 Growth of Education: Education increased political awareness, while unemployment and under-employment among educated Indians highlighted the poverty and economic backwardness created under colonial rule.
🟢 Reaction to Westernisation: Thinkers such as Swami Vivekananda, Bankim Chandra Chatterjee and Swami Dayanand Saraswati challenged notions of Western superiority and emphasised India’s civilisational heritage.
🟢 Militant School of Thought: A new generation advocated hatred of foreign rule, Swaraj, direct political action, faith in the masses and personal sacrifice.
🟢 Trained Leadership: The emergence of leaders capable of channelising mass political energy became particularly important during the Swadeshi Movement against the Partition of Bengal.
📍 Core Ideas of Extremists
🟢 Foreign rule was viewed as the fundamental cause of India’s problems.
🟢 Swaraj was regarded as the ultimate goal.
🟢 Direct political action was necessary rather than dependence solely on petitions.
🟢 Masses had the capacity to challenge colonial authority.
🟢 Self-sacrifice was considered essential for true nationalism.
📍 Objective: Meaning of Swaraj
🟢 Bal Gangadhar Tilak: Indian control over administration, without necessarily completely severing relations with Britain.
🟢 Bipin Chandra Pal: Complete autonomy and absolute freedom from British control.
🟢 Aurobindo Ghosh: Self-rule within the framework of the British imperial structure.
📍 UPSC MAINS
Q. Examine the factors responsible for the rise of militant nationalism in India in the early 20th century. How did the Extremists differ from the Moderates in their approach to the national movement?

🔆 WOMEN IN MODERN INDIA
🔆 BACKGROUND: THE WOMEN’S QUESTION
🟢 In the 19th century, Western observers such as James Mill used the “women’s question” to construct a civilizational critique of India.
🟢 By the 19th century, the ideal of purdah had become widespread among Hindu and Muslim women, across elite and non-elite groups, although its practical implications varied across communities.
🔆 PROMINENT WOMEN REFORMERS & EDUCATIONISTS
📍 1. Tarabai Shinde
🟢 A Marathi woman from Berar who published A Comparison Between Women and Men in 1882.
🟢 Her work challenged gender inequalities and discriminatory social attitudes towards women.
📍 2. Pandita Ramabai
🟢 First woman in India to receive the titles Pandita and Sarasvati after examination by the faculty of the University of Calcutta.
🟢 Founded the Arya Mahila Samaj, which worked for girls’ education and against child marriage.
🟢 Authored Stri Dharma Niti (Morals for Women).
🟢 Testified before the Hunter Commission on Education in India.
🟢 Established Sharda Sadan in Bombay, a home-cum-school for widows.
📍 3. Sister Subbalakshmi
🟢 Recognised for her service to women and girls in the Madras Presidency.

🟢 Founded the Muslim Women’s Association in 1916 to promote women’s education and employment.
🔆 WOMEN, WORK & ECONOMIC CHANGE
📍 1. Changing Social Expectations
🟢 From the late 19th century, increasingly socially mobile peasant families began confining women to household work.
🟢 Women were increasingly idealised as wives and mothers, and household responsibilities were treated as sacred duties rather than economically valuable work.
📍 2. Mechanisation & Loss of Livelihoods
🟢 During the early 20th century, mechanisation led many women engaged in traditional crafts to lose their occupations.
🟢 Women received lower wages than men and were often treated as members of family units rather than independent economic contributors.
🔆 KEY THEMES FOR UPSC
🟢 Social reform: Efforts to challenge child marriage, gender discrimination and restrictions on women.
🟢 Women’s education: Reformers promoted access to education and opportunities for social participation.
🟢 Economic inequality: Women faced occupational displacement, wage discrimination and undervaluation of domestic work.
🟢 Patriarchal norms: Social expectations shaped women’s mobility, employment and family responsibilities.

🔆 REVERSE VACCINOLOGY: TOWARDS A UNIVERSAL PNEUMOCOCCAL VACCINE
📍 Why in News?
🟢 British scientists have taken an important first step towards developing a universal pneumococcal vaccine using reverse vaccinology.
🔆 WHAT IS REVERSE VACCINOLOGY?
🟢 A vaccine-discovery approach that begins in silico (computer-based) using a pathogen’s genetic information rather than starting with the pathogen itself in the laboratory.
🟢 Term coined by: Rino Rappuoli in 2000.
🔆 HOW DOES IT WORK?
🟢 Genome Sequencing: Sequence the pathogen’s genome to identify its genes.
🟢 Bioinformatics: Analyse genes to identify those encoding surface proteins.
🟢 Protein Selection: Select accessible proteins with little or no similarity to human proteins.
🟢 Evaluation: Assess protein shape, stability and potential to trigger a strong, lasting immune response.
🟢 Testing: Use laboratory assays or animal studies to assess immune responses and protection.
🔆 KEY FEATURES
🟢 Reduces the time required to identify suitable antigens.
🟢 Useful against pathogens that are difficult to grow in culture.
🟢 Helps identify protective antigens when conventional approaches face challenges.
🟢 May identify proteins shared across different serotypes, supporting broader vaccine coverage.
🔆 LIMITATIONS
🟢 Cannot directly identify carbohydrates and other cellular structures not encoded by the genome.
🔆 APPLICATIONS
🟢 Neisseria meningitidis: First used for vaccine development against this pathogen.
🟢 COVID-19: Genome sequencing helped identify the gene encoding the spike protein.
🟢 Pneumococcal Vaccine: Being explored to identify proteins that could support a universal vaccine.
🔆 UPSC PRELIMS QUICK REVISION
🟢 Approach: Genome-based, computer-assisted vaccine discovery.
🟢 Key disciplines: Bioinformatics, genomics, proteomics and immunology.
🟢 Key advantage: Potential to identify antigens shared across serotypes.
🟢 Major limitation: Does not directly identify non-genome-encoded cellular structures such as carbohydrates.

🔆 COLONIAL KNOWLEDGE
🔆 WHAT IS COLONIAL KNOWLEDGE?
🟢 European colonial domination depended not only on military strength, political power and economic wealth but also on “cultural technologies of rule” — a concept associated with Nicholas Dirks.
🟢 Knowledge of Indian laws, customs, languages, literature and geography helped the British understand and administer the colonised territory.
🔆 WARREN HASTINGS: MOTIVATIONS
🟢 Wanted to end Robert Clive’s Dual Government system and establish territorial rule over Bengal.
🟢 Opposed simply imposing English laws and customs; favoured ruling Indians according to their own traditions.
🟢 Sought to understand Indian manners, customs, laws and literature to make British rule more acceptable and reduce resistance.
🔆 ASIATIC SOCIETY OF BENGAL
🟢 Established: 1784 by William Jones, a judge of the Supreme Court at Calcutta.
