๐Ÿ”† RISE OF MILITANT NATIONALISM (EXTREMISM)

๐Ÿ“ Background
๐ŸŸข By the dawn of the 20th century, militant nationalists emerged within the Indian national movement.
๐ŸŸข Important leaders included Bal Gangadhar Tilak, Aurobindo Ghosh, Bipin Chandra Pal, Lala Lajpat Rai, Raj Narain Bose, Ashwini Kumar Datta and Vishnu Shastri Chiplunkar.
๐ŸŸข They rejected excessive faith in British rule and emphasised Swaraj, mass participation, direct political action and self-sacrifice.

๐Ÿ“ Factors Behind the Rise of Extremists

๐ŸŸข Loss of Faith in British Rule: Economic drain, British indifference towards Indian demands and the failure of constitutional methods weakened faith in moderate politics.

๐ŸŸข Famine & Plague: The 1896โ€“97 famine and bubonic plague exposed the inadequacy and insensitive nature of British relief measures, generating widespread resentment.

๐ŸŸข Political Despondency: Limited achievements of the Moderates, along with measures such as the arrest of Tilak and the Sedition Act, created frustration among nationalists.

๐ŸŸข Curzonโ€™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.

๐ŸŸข 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.

๐ŸŸข Impact of Reform Movements: Movements such as Arya Samaj and thinkers such as Swami Vivekananda encouraged self-respect, national consciousness and social rejuvenation.

๐ŸŸข 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.

๐ŸŸข Reaction to Westernisation: Thinkers such as Swami Vivekananda, Bankim Chandra Chatterjee and Swami Dayanand Saraswati challenged notions of Western superiority and emphasised Indiaโ€™s civilisational heritage.

๐ŸŸข Militant School of Thought: A new generation advocated hatred of foreign rule, Swaraj, direct political action, faith in the masses and personal sacrifice.

๐ŸŸข Trained Leadership: The emergence of leaders capable of channelising mass political energy became particularly important during the Swadeshi Movement against the Partition of Bengal.

๐Ÿ“ Core Ideas of Extremists
๐ŸŸข Foreign rule was viewed as the fundamental cause of Indiaโ€™s problems.
๐ŸŸข Swaraj was regarded as the ultimate goal.
๐ŸŸข Direct political action was necessary rather than dependence solely on petitions.
๐ŸŸข Masses had the capacity to challenge colonial authority.
๐ŸŸข Self-sacrifice was considered essential for true nationalism.

๐Ÿ“ Objective: Meaning of Swaraj
๐ŸŸข Bal Gangadhar Tilak: Indian control over administration, without necessarily completely severing relations with Britain.
๐ŸŸข Bipin Chandra Pal: Complete autonomy and absolute freedom from British control.
๐ŸŸข Aurobindo Ghosh: Self-rule within the framework of the British imperial structure.

๐Ÿ“ 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?

๐Ÿ”† ADDITIVE MANUFACTURING (3D PRINTING)

๐ŸŸข Additive Manufacturing (AM) is a technology that creates 3D objects layer-by-layer from a digital 3D/CAD model.
๐ŸŸข It is commonly known as 3D printing and brings together computing, electronics, design software and materials science.

๐Ÿ“ How Additive Manufacturing Works
๐ŸŸข Digital Design: A model is created using CAD, 3D scanning or AI-based tools.
๐ŸŸข STL File: Represents the 3D model through triangular surfaces and guides the printing process.
๐ŸŸข Slicing: Software divides the model into hundreds or thousands of horizontal layers.
๐ŸŸข Printing: The machine builds the object layer-by-layer by adding successive layers of material.
๐ŸŸข Post-processing: The printed object is further processed to make it market-ready.
๐ŸŸข There are currently 40+ AM processes at market and R&D stages.

๐Ÿ“ Applications
๐ŸŸข Aerospace & Defence
๐ŸŸข Healthcare
๐ŸŸข Electronics
๐ŸŸข Construction
๐ŸŸข Enables greater design flexibility and layer-wise manufacturing.

๐Ÿ“ National Strategy for Additive Manufacturing (NSAM)
๐ŸŸข Released by MeitY in 2022 as Indiaโ€™s policy framework for developing domestic AM capabilities.
๐ŸŸข Aim: Capture 5% of the global AM market and contribute nearly US$1 billion to Indiaโ€™s GDP.

๐Ÿ“ Key NSAM Targets
๐ŸŸข Develop 50 India-specific AM technologies
๐ŸŸข Nurture 100 start-ups
๐ŸŸข Create 500 new products
๐ŸŸข Train 1 lakh skilled workers
๐ŸŸข Build capabilities across 10 manufacturing sectors

๐Ÿ“ NSAM 2.0
๐ŸŸข The proposed NSAM 2.0 seeks to accelerate Indiaโ€™s AM ecosystem.
๐ŸŸข Focus on IPR generation, digital integration and commercialisation of globally competitive technologies.
๐ŸŸข Improve affordability of AM machines and materials through clusters.
๐ŸŸข Expand the AM start-up ecosystem and support defence applications.
๐ŸŸข Promote SDG-driven pilot programmes.
