Nation Commemorates 150th Birth Anniversary of Bhagwan Birsa Munda

What’s the News?

• The nation observed the 150th birth anniversary of Bhagwan Birsa Munda, a revered tribal icon and freedom fighter.
• His birth anniversary is celebrated as Janjatiya Gaurav Divas (Tribal Pride Day) to honor the contributions of tribal communities to India's history and freedom struggle.

Who Was Birsa Munda?

• Born on November 15, 1875, in Ulihatu (present-day Khunti, Jharkhand), Birsa Munda emerged as a tribal leader, social reformer, and spiritual figure - revered as “Dharti Aaba” (Father of the Earth).
• Led the Ulgulan (“Great Tumult”) movement (1899–1900) against British land alienation, forced labour, exploitative intermediaries (thikadars), and missionary interference.
• Advocated for restoration of the Khuntkatti land system, promoted anti-alcoholism, cultural revival, and self-rule - encapsulated in his slogan: “Abua Raj setar jana, Maharani Raj tundu jana” (End the Queen’s rule, establish our own rule).
• Died in custody at age 25 in 1900; his movement directly contributed to the enactment of the Chhotanagpur Tenancy Act, 1908, safeguarding tribal land rights.

Janjatiya Gaurav Diwas

• Declared by the Union Cabinet on November 10, 2021, and first observed on November 15, 2021, to institutionalise recognition of tribal freedom fighters often excluded from mainstream narratives.
• Aims to promote cultural visibility, political recognition, and inclusive socio-economic development of tribal communities.
• Aligns with national efforts to mainstream tribal history - e.g., setting up tribal museums (e.g., Ranchi Prison Museum, Rajpipla Tribal Museum), establishing Shri Govind Guru Chair for tribal language preservation, and integrating tribal narratives into school curricula.

Key Development Initiatives Launched/Expanded

• Pradhan Mantri Janjati Adivasi Nyaya Maha Abhiyan (PM-JANMAN):
  • Targets Particularly Vulnerable Tribal Groups (PVTGs) across 18 states.
  • Key components include:
    • 4.90 lakh pucca houses by 2026.
    • 8,000 km roads, 1,000 mobile medical units, 2,500 Anganwadi centres, and 1 lakh solar-powered households.
    • Focus on safe housing, clean drinking water, sanitation, healthcare, education, and livelihoods.
• Eklavya Model Residential Schools (EMRS):
  • 42 new EMRS inaugurated, bringing the total to over 700 nationwide.
  • Objective: Provide quality education (Classes VI–XII) to Scheduled Tribe students in remote areas, with comprehensive physical, mental, and social development.
  • Facilities include hostels, labs, libraries, sports infrastructure, and digital classrooms.
  • Enrollment prioritises ST children from rural/remote habitations.

NDA Secures Majority in Bihar Assembly Elections; BJP Emerges as Single Largest Party

What’s the News?

• The results for the Bihar Assembly Elections have been declared.
• The National Democratic Alliance (NDA) has secured a decisive majority, winning over 200 seats in the assembly.
• The Bharatiya Janata Party (BJP) has emerged as the single largest party in the state.

Seat Breakdown & Political Shifts

• NDA Total: 202 seats
  • BJP: 91
  • JD(U): 83
  • LJP(RV): 21
  • HAM(S): 5
  • RLM: 2 , ,
• Mahagathbandhan (MGB): ~41 seats
  • RJD: 35
  • Congress: 6
  • Smaller left parties (CPI, CPI-ML, etc.): ≤5
• Others:
  • AIMIM: 6
  • Jan Suraaj Party (JSP): 0 (blank debut) ,

Key Electoral Trends & Drivers

• Strike Rates: BJP recorded an 89% strike rate, far exceeding expectations and surpassing its 2020 performance.
• Social Welfare + Modi Wave: The “Nimo wave” (Nitish + Modi) combined JD(U)’s welfare outreach (e.g., Mukhyamantri Kanya Utthan Yojana) with PM Modi’s aggressive campaigning centred on governance and anti-corruption messaging.
• Women Voter Turnout: Record female participation reportedly bolstered NDA’s rural and semi-urban gains.
• Strategic Gains in Seemanchal: BJP made inroads in Muslim-dominated border districts by foregrounding national security and anti-infiltration narratives.
• MGB’s Collapse: RJD’s over-reliance on Yadav-centric candidature and unrealistic poll promises (e.g., ₹2,500/month to all women) failed to resonate.

Constitutional & Governance Implications

• Fifth Term for Nitish Kumar: Set to take oath as Chief Minister again, reinforcing Bihar’s trend of stable coalition governance under the NDA, despite leadership tussles over “big brother” status.
• Alliance Cohesion Test: With BJP now clearly ahead of JD(U), internal negotiations on portfolios - including possible Deputy CM demand by LJP(RV) - will shape the next government’s functioning.
• Model for Future State Polls: The win is being interpreted as a validation of the BJP’s “welfare populism + identity consolidation” model ahead of UP, MP, and Rajasthan polls in 2026–27.
