States and union territories of India are the primary first-level administrative and territorial units of the Republic of India. Established by the Constitution of India in 1950 and reshaped by later statutes such as the States Reorganisation Act, 1956 and the Constitution (Seventh Amendment) Act, 1956, they encompass diverse historical regions including former princely states like Mysore State and colonial provinces such as the Bombay Presidency. The configuration influences representation in the Parliament of India, allocation under the NITI Aayog, and jurisdiction of the Supreme Court of India.

History and evolution

The premodern map included polities like the Mughal Empire, Maratha Empire, and Kingdom of Mysore, later altered by the East India Company and the British Raj through instruments such as the Government of India Act 1935. Post-independence consolidation involved integration of princely states under leaders such as Sardar Vallabhbhai Patel and treaties like the Instrument of Accession. The States Reorganisation Commission led to reorganisation on linguistic lines, formalised by the States Reorganisation Act, 1956; subsequent events include creation of Himachal Pradesh statehood, formation of Arunachal Pradesh, the bifurcation creating Jharkhand, Chhattisgarh, and Uttarakhand, and the 2019 reorganisation turning Jammu and Kashmir (state) into the union territories of Jammu and Kashmir and Ladakh. Judicial milestones include rulings from the Supreme Court of India on state boundaries and the Kesavananda Bharati v. State of Kerala doctrine that shaped constitutional amendments.

Constitutional and administrative framework

The Constitution of India (Parts VI and VII) defines powers of states and union territories, distinguishing responsibilities retained by the President of India and state governors like Governor of Maharashtra. Federal mechanisms involve the Union List, State List, and Concurrent List; fiscal relations are mediated by the Finance Commission of India and the Constitutional Amendment of 1991 era reforms. Union territories such as Delhi and Puducherry have special arrangements under statutes including the National Capital Territory of Delhi Act, 1991 and treaties governing former colonial enclaves like Pondicherry (French India). Administrative structures feature state chief ministers (e.g., Chief Minister of West Bengal), state legislatures such as the Maharashtra Legislative Assembly, and institutions like the Election Commission of India overseeing state and territorial elections.

Current list and demographics

India currently comprises 28 states including Uttar Pradesh, Maharashtra, Bihar, West Bengal, and Tamil Nadu, and 8 union territories including National Capital Territory of Delhi, Chandigarh, and Ladakh. Population data from decennial censuses and estimates involve regions such as Kerala with high literacy indicators, Assam in the Northeast India cluster, and populous states like Uttar Pradesh affecting representation in the Lok Sabha. Cities and urban agglomerations include Mumbai, Delhi, Bengaluru, Kolkata, and Chennai. Demographic diversity links to languages listed in the Eighth Schedule to the Constitution of India such as Hindi, Bengali, Tamil, Telugu, and Marathi, while minority protections reference the National Commission for Minorities and provisions for Scheduled Castes and Scheduled Tribes like those recognised in Jharkhand and Chhattisgarh.

Governance and political representation

States elect governments via state legislative elections where parties like the Bharatiya Janata Party, Indian National Congress, Trinamool Congress, and regional parties such as the Dravida Munnetra Kazhagam compete. Chief ministers (e.g., Chief Minister of Karnataka) head state councils of ministers; governors represent the President of India in states. Representation in the Rajya Sabha and Lok Sabha is allocated by state population and delimitation orders from the Delimitation Commission of India. Law-and-order and policing remain under state purview, with interstate coordination involving agencies such as the Central Bureau of Investigation and judicial oversight by the High Court of Judicature at Bombay and other state high courts.

Economic and geographic profiles

States and union territories display varied economies: industrial hubs like Gujarat and Maharashtra, IT centres such as Karnataka and Telangana, and agrarian regions including Punjab and Haryana. Resource-rich areas include Odisha for minerals, Arunachal Pradesh for hydropower potential, and Assam for petroleum. Geographic diversity spans the Himalayas in Himachal Pradesh and Uttarakhand, the Thar Desert in Rajasthan, coastal plains of Kerala and Goa, and the Andaman and Nicobar Islands in the Bay of Bengal. Economic planning engages institutions like the Reserve Bank of India and state industrial development corporations; infrastructure projects include corridors such as the Golden Quadrilateral and ports like Kolkata Port and Nhava Sheva.

Inter-state relations and disputes

Inter-state issues involve river water disputes adjudicated under the Inter-State River Water Disputes Act, 1956 with tribunals for cases like the Cauvery water dispute (between Karnataka and Tamil Nadu) and the Krishna water dispute; boundary disputes include those between Assam and Nagaland and long-standing disagreements near Mizoram and Manipur. Fiscal tensions arise over goods and services taxation coordinated by the Goods and Services Tax Council; cooperative mechanisms include the Inter-State Council and arbitration via the Supreme Court of India. Security coordination addresses insurgencies in regions such as Jammu and Kashmir and Northeast India, involving central forces like the Indian Army and paramilitary units such as the Border Security Force.
