IAS PCS Mission 2026: Daily Study Material – 20 Jan 2026
NCERT History: Class 7 Chapter-5 (Rulers and Buildings)
Chapter 5, “Rulers and Buildings,” explores the architectural achievements between the eighth and eighteenth centuries, highlighting how kings expressed their power, devotion, and cultural influences through construction.
1. Types of Structures
During this period, kings and their officers built two distinct kinds of structures:
- Forts, Palaces, and Tombs: These were safe, protected, and grandiose places of rest for the rulers in this world and the next.
- Structures for Public Activity: These included temples, mosques, tanks, wells, caravan serais, and bazaars. Rulers built these for the comfort and use of their subjects to win their praise and care for them.
2. Engineering Skills and Construction
The precision required for these buildings, like placing inscriptions on the curved surface of the Qutb Minar, demonstrates the high level of skill possessed by craftspersons.
- Trabeate (Corbelled) Principle: Between the eighth and thirteenth centuries, architects used this style, where roofs, doors, and windows were made by placing a horizontal beam across two vertical columns.
- Arcuate Principle: From the twelfth century, two major technological developments appeared:
- The weight of the superstructure above doors and windows was sometimes carried by arches.
- Limestone cement was increasingly used in construction, which, when mixed with stone chips, hardened into high-quality concrete, making the construction of large structures easier and faster.
3. Building Temples, Mosques, and Tanks
Temples and mosques were beautifully constructed because they were places of worship and meant to demonstrate the power, wealth, and devotion of the patron.
- Temples as Symbols: A king would often name a temple after himself (e.g., King Rajarajadeva built the Rajarajeshvara temple for the worship of his god, Rajarajeshvaram) to appear like a god.
- The Largest Temples: These were usually built by kings, while other, lesser deities in the temple were the gods and goddesses of the ruler’s allies and subordinates.
- Mosques and Sultans: While Muslim Sultans and Padshahs did not claim to be incarnations of god, Persian court chronicles described the Sultan as the “Shadow of God”.
- Water Importance: Rulers often built tanks and reservoirs to provide water to the public, such as Iltutmish’s Hauz-i-Sultani (the King’s Reservoir).
4. Why Were Temples Targeted?
Because kings built temples to demonstrate their devotion and power, they were frequent targets during invasions.
- When rulers attacked one another’s kingdoms, they often targeted these buildings to seize the wealth and prestige associated with them.
- For example, the Chola king Rajendra I filled a temple he built with statues seized from defeated rulers, and Sultan Mahmud of Ghazni attacked the Somnath temple during his campaigns.
5. Mughal Architecture
The Mughals made architecture even more complex by fusing different styles.
- Chahar Bagh: Babur was fond of formal gardens, placed within rectangular walled enclosures and divided into four quarters by artificial channels, a layout known as chahar bagh.
- Pietra Dura: During Shah Jahan’s reign, a series of pietra dura inlays (colored, hard stones placed in depressions carved into marble or sandstone) were used behind his throne in the Diwan-i-Am in Delhi.
- The Taj Mahal: Shah Jahan adapted the river-front garden for the layout of the Taj Mahal, where the white marble mausoleum was placed on a terrace by the edge of the river Yamuna, with the garden to its south.
6. Region and Empire
As empires grew, architectural styles were shared across regions.
- In Vijayanagara, the elephant stables of the rulers were strongly influenced by the style of architecture found in the adjoining Sultanates of Bijapur and Golconda.
- In Vrindavan, temples were built in architectural styles very similar to the Mughal palaces in Fatehpur Sikri.
- Mughal rulers were particularly skilled in adapting regional architectural styles, such as the “Bangla dome” from Bengal, into their own buildings.

Complete Study Notes: Rulers and Buildings
⚖️Indian Polity: Understanding Articles 42-45
Part IV of the Constitution, Articles 42 to 45 focus on humanizing the workplace, ensuring a dignified standard of living, and prioritizing the foundation of education. These articles are categorized primarily as Socialistic and Liberal-Intellectual principles.
Human Welfare and Early Education: Articles 42–45
These directives aim to bridge the gap between mere survival and a life of dignity. They guide the State to create an environment where work is humane and the future (children) is secured.
Article 42: Humane Conditions of Work and Maternity Relief
This article recognizes that the “Right to Work” (from Art. 41) is meaningless if the work environment is oppressive or hazardous.
- Mandate: The State shall make provision for securing just and humane conditions of work and for maternity relief.
- Significance: It emphasizes that workers are not just “tools of production” but human beings with rights to health and dignity.
- Implementation:
- The Maternity Benefit Act, 1961 (and 2017 amendment): Provides for paid leave and benefits for pregnant employees.
- Factories Act, 1948: Ensures safety, health, and welfare of workers in factories.
Article 43: Living Wage for Workers
Article 43 moves beyond “Minimum Wage” toward the concept of a “Living Wage.”
- Mandate: The State shall endeavor to secure to all workers (agricultural, industrial, or otherwise) a living wage and conditions of work ensuring a decent standard of life and full enjoyment of leisure and social and cultural opportunities.
- Promotion of Cottage Industries: It specifically directs the State to promote cottage industries on an individual or co-operative basis in rural areas (Gandhian Principle).
Difference between Minimum Wage and Living Wage
- Minimum Wage: Bare minimum to cover food, clothing, and shelter.
- Living Wage: Covers basic needs plus education, health, and social security.
Article 43A: Participation of Workers in Management
- Origin: Added by the 42nd Amendment Act (1976).
- Mandate: The State shall take steps to secure the participation of workers in the management of undertakings, establishments, or other organizations engaged in any industry.
- Goal: To promote industrial democracy and reduce the gap between owners and laborers.
Article 43B: Promotion of Co-operative Societies
- Origin: Added by the 97th Amendment Act (2011).
- Mandate: The State shall endeavor to promote voluntary formation, autonomous functioning, democratic control, and professional management of co-operative societies.
Article 44: Uniform Civil Code (UCC)
This is one of the most discussed and debated articles in the Indian Constitution.
- Mandate: The State shall endeavor to secure for the citizens a Uniform Civil Code throughout the territory of India.
- Definition: A UCC would replace personal laws based on the scriptures and customs of each major religious community in the country with a common set of laws governing every citizen.
- Scope: It covers secular matters like marriage, divorce, maintenance, inheritance, and adoption.
- Current Status: While Goa has a common family law (Portuguese Civil Code), the UCC has not been implemented nationally, though various states have recently moved toward drafting their own versions.
Article 45: Provision for Early Childhood Care and Education
This article was significantly altered by the 86th Amendment Act (2002).
- Original Provision: Provided for free and compulsory education for all children until the age of 14.
- Current Mandate: The State shall endeavor to provide early childhood care and education for all children until they complete the age of six years.
- The Shift: After the 86th Amendment, the “Right to Education” for children aged 6–14 became a Fundamental Right (Article 21A). Article 45 now focuses on the “pre-school” or Anganwadi stage (0–6 years).

“The Hindu” Editorial Analysis (20-January-2026)
Here is a detailed analysis of the The Hindu Editorials for January 20, 2026, categorized by syllabus relevance for UPSC preparation.
1. Regional Saffron: The BJP’s Ascent in Maharashtra
Syllabus: GS Paper 2 (Polity; Important aspects of governance; Salient features of the Representation of People’s Act).
Context: An analysis of the recent municipal corporation election results in Maharashtra, signaling a major shift in the state’s political landscape.
Key Points:
- BJP’s Electoral Dominance: The BJP has emerged as the single largest party in key cities like Pune, Nagpur, and Nashik, securing approximately 1,425 out of 2,869 seats across 29 municipal corporations.
- Identity Politics Reimagined: The party has “smartly” adopted the legacy of Balasaheb Thackeray by blending Marathi nativism with Hindu communalism to cater to changing urban demographics.
- Leadership Growth: Chief Minister Devendra Fadnavis has solidified his standing, successfully balancing ideological expectations with the complexities of governance.
- Decline of Traditional Blocs: Power centers like the Pawar and Thackeray families performed poorly, with the BJP-Shinde alliance seizing control of the Brihanmumbai Municipal Corporation (BMC)—a body Uddhav Thackeray controlled for 25 years.
UPSC Relevance: Essential for questions regarding “Regionalism vs. National Parties,” “Electoral Politics and Demographics,” and the “Evolution of Ideological Narratives in India.”
Detailed Analysis:
- Demographic Leverage: The editorial notes that the BJP has utilized migration-led population changes to win over Hindi-speaking voters, effectively weakening traditional nativist politics.
- Shiv Sena’s Struggle: Various Sena factions are finding it difficult to adapt to a changing population because their “nativist” past restricts their political maneuvering.
- The Inclusivity Argument: The lekh warns that replacing nativism with communalism is not ideal for the state; it suggests the BJP should drive its ambitions through a more inclusive platform.
2. Fractured Yemen: Geopolitical Fault Lines
Syllabus: GS Paper 2 (International Relations; Effect of policies and politics of developed/developing countries on India’s interests).
Context: Recent escalations in fighting between Yemen’s Saudi-backed government and the UAE-backed Southern Transitional Council (STC).
Key Points:
- Regional Rivalries: The conflict brought Saudi-UAE tensions into the open, with Riyadh accusing Abu Dhabi of transferring weapons to Yemeni separatists.
- Houthi Entrenchment: As southern factions remained divided, the Houthi militia (Ansar Allah) strengthened its control over northern population centers.
- Humanitarian Toll: Yemen faces one of the world’s worst crises, with millions on the brink of famine, a ruined economy, and devastated infrastructure.
- UAE Withdrawal: Following a public rebuke from Saudi Arabia, the UAE announced its withdrawal of forces from Yemen and an end to its “counterterrorism operations.”
UPSC Relevance: Vital for understanding “West Asian Geopolitics,” “Proxy Wars,” and “International Humanitarian Crisis Management.”
Detailed Analysis:
- Federal Structure Solution: For lasting peace, the editorial advocates for all Yemeni factions to establish a federal governance structure to address power dynamics and historical grievances.
- Burying the Hatchet: The piece emphasizes that Saudi Arabia and the UAE must work jointly for stability in their neighbor rather than supporting opposing proxies.
- Impact of Air Power: Saudi air power was critical in allowing government forces to recapture lost areas in Hadhramaut and al-Mahra.
3. Calling out the ED’s Actions: The Media Trials
Syllabus: GS Paper 2 (Statutory, Regulatory and Quasi-judicial bodies; Important aspects of governance).
Context: A critique of the Enforcement Directorate’s (ED) recent pattern of investigations and the role of “media trials” in damaging reputations before judicial scrutiny.
Key Points:
- Inversion of Logic: Under the PMLA (2002), the ED is accused of treating money laundering as independent of an underlying crime, rather than first establishing a “scheduled offence.”
- Procedural Overreach: Under Section 50 of the PMLA, the agency can summon anyone and record statements under oath that reverse the presumption of innocence for bail.
- Judicial Setbacks: Courts, including the Supreme Court, have stayed ED probes, observing that the agency was “crossing all limits” and violating federal principles.
- Institutional Integrity: Cases of ED officials caught taking bribes or extorting money have undermined the agency’s moral authority.
UPSC Relevance: Crucial for topics like “Abuse of Investigative Powers,” “Judicial Oversight,” and “Ethics in Journalism.”
Detailed Analysis:
- Media Complicity: The editorial criticizes journalists for acting as “conduits” for selective leaks, noting that “journalism is not stenography.”
- Constitutional Guardrails: The piece argues that only firm limits can prevent investigative authority from mutating into arbitrary state power.
- Democratic Health: It likens the ED to a “hound let loose,” warning that false or weak cases normalize authoritarian overreach and erode faith in institutions.
4. Diplomatic White Spaces: India’s 2026 Strategy
Syllabus: GS Paper 2 (Bilateral, regional and global groupings and agreements involving India).
Context: Exploring India’s opportunities to lead in “diplomatic white spaces”—gaps in global leadership where major powers are at odds.
Key Points:
- India-EU FTA: The presence of EU leadership at the 2026 Republic Day parade signals a push for the India-EU Free Trade Agreement as a “de-risking compact.”
- Navigating BRICS: As the 2026 chair, India must steer the group away from anti-West rhetoric toward practical delivery through the New Development Bank.
- The Quad’s Utility: India can make the Quad useful for Indian Ocean littoral states by converting its maritime domain awareness capabilities into accessible services.
- New Tables: The invitation for India to join “Pax Silica” (a US-led AI and semiconductor club) highlights the shift toward smaller, functional diplomatic coalitions.
UPSC Relevance: Significant for questions on “India’s Global Leadership,” “Multi-alignment Strategy,” and the “Future of Multilateralism.”
Detailed Analysis:
- Small Tables, Big Dividends: The editorial suggests that in a divided world, outcomes are shifting to smaller coalitions where things actually get done, rather than large, weak forums like the UN.
- Strategic Balance: India’s momentum in 2026 will come from turning “white spaces” into working arrangements for global public goods like AI standards and supply chain security.
5. A Centrist Lens on ‘Illegal Immigration’
Syllabus: GS Paper 2 (Electoral Reforms; Constitutional Bodies; Citizenship).
Context: An analysis of the political reactions to the Special Intensive Revision (SIR) of electoral rolls and the potency of the undocumented immigration issue.
Key Points:
- Voter List Revision: Despite handling disputes, there is an “overwhelming sense” that revising voter lists is necessary to remove dead and duplicate entries.
- Public Anxiety: The editorial notes that the opposition’s denial of undocumented immigrants in the face of evidence alienates a section of the public concerned with national security.
- Institutional Failure: The SIR 2.0 has relied on error-prone paper-based forms and physical hearings (summoning even Nobel laureates) instead of fully using the ECINet digital infrastructure.
- Electoral Integrity: The exercise omitted nearly 6.5 crore electors, leading to accusations of “vote chori” from the opposition.
UPSC Relevance: Key for understanding “Electoral Roll Integrity,” “Internal Security Challenges,” and the “Politics of Citizenship.”
Detailed Analysis:
- Nuanced Conversation: A prudent course would be to build a conversation focusing on legal work authorizations and national security without dismissive rhetoric.
- Digital-First Remedy: The piece advocates for a system built on online document upload and backend verification to make the process fairer and more humane.
- Safeguarding Trust: Electoral reform succeeds through inclusion and the responsible use of digital tools, safeguarding the foundations of public trust.
