Geographical Landmarks — Recently Created Districts, States and Geographical Changes
Overview
Geographical Landmarks in the context of current events covers the administrative and geographical changes that have occurred in India and Tamil Nadu in recent years. This includes the creation of new districts, reorganization of states, and significant geographical developments that candidates are expected to know for TNPSC Group IV examination.
This topic bridges static geography with current affairs. Questions typically test whether you know the newest districts in Tamil Nadu, recently formed Union Territories, renamed cities/places, and landmark geographical decisions.
Mastery requires memorizing specific dates, numbers, and names — there is no shortcut. However, understanding the pattern of state reorganization in India helps you anchor these facts logically rather than through rote memorization alone.
Key Concepts
- District Formation Authority: State governments create new districts through executive orders; no constitutional amendment is required. The State Legislative Assembly need not pass a law for district creation.
- State/UT Reorganization: Creating a new state or Union Territory requires a Constitutional Amendment under Article 3. Parliament has the sole authority; state legislature opinion is sought but not binding.
- Tamil Nadu District Evolution: TN originally had 13 districts at formation (1956). As of 2024, Tamil Nadu has 38 districts. The most recent additions came in 2019 and 2020.
- Jammu & Kashmir Reorganisation (2019): The state was bifurcated into two Union Territories — J&K (with legislature) and Ladakh (without legislature) — effective 31 October 2019.
- Telangana Formation (2014): India's 29th state, carved from Andhra Pradesh on 2 June 2014. Hyderabad served as joint capital for 10 years.
- City/Place Renaming: Several cities have been officially renamed — Allahabad to Prayagraj (2018), Faizabad to Ayodhya (2018), Gurgaon to Gurugram (2016).
- Article 370 Abrogation: Special status of J&K was revoked on 5 August 2019, leading to its reorganization into Union Territories.

Worked Examples
Example 1: Which district of Tamil Nadu was formed in 2020?
Solution: Mayiladuthurai was carved out of Nagapattinam district in 2020. It is the 38th and newest district of Tamil Nadu.
Example 2: When was Telangana formed and from which state?
Solution: Telangana was formed on 2 June 2014 by bifurcating Andhra Pradesh. It became India's 29th state with Hyderabad as capital.
Example 3: How many Union Territories does India have after the J&K reorganization?
Solution: India has 8 Union Territories:
- Delhi
- Puducherry
- Chandigarh
- Andaman & Nicobar Islands
- Lakshadweep
- Dadra and Nagar Haveli and Daman and Diu (merged in 2020)
- Jammu & Kashmir
- Ladakh
Common Mistakes
- Confusing 37 with 38 districts: Students often forget Mayiladuthurai (2020) and answer 37. Always remember: 5 districts in 2019 + 1 in 2020 = 38 total.
- Stating J&K is still a state: After August 2019, J&K is a Union Territory with legislature, not a state. India now has 28 states, not 29.
- Mixing up Tirupattur and Ranipet: Both were carved from Vellore in 2019. Tirupattur is in the northern part; Ranipet lies between Vellore and Kancheepuram.
- Forgetting the Dadra-Daman merger: Dadra and Nagar Haveli and Daman and Diu were merged into a single UT in January 2020. Students sometimes count them as two separate UTs, getting 9 instead of 8.
- Assuming Parliament can create districts: District creation is a state subject done through executive order. Only state/UT reorganization needs Parliament.
