Assam is the Brahmaputra Valley state that grows more than half of India's tea, sits atop Asia's oldest continuously operating oil refinery, and hosts the world's largest population of the greater one-horned rhinoceros — all while managing near-annual flooding, a decades-long citizenship debate, and the aftermath of an insurgency that only formally ended in 2023.

Before 1963, Assam's borders held nearly all of India's Northeast. Nagaland, Meghalaya, Mizoram and Arunachal Pradesh were each carved from what was, at independence, a single undivided Assam.

Snapshot

Assam is governed as a standard Indian state with a unicameral 126-seat Legislative Assembly; BJP's Himanta Biswa Sarma won a second consecutive term as Chief Minister in May 2026. It is the historic seat of the Ahom dynasty, which ruled the Brahmaputra Valley for roughly 600 years and twice repelled Mughal invasions; the birthplace of India's modern tea industry, discovered in 1823 and now the world's largest single tea-growing region; and, more recently, the site of Tata Electronics' new semiconductor assembly plant, a bet on diversifying an economy long dependent on tea and crude oil. It also carries some of India's most persistent structural challenges: near- annual Brahmaputra flooding, a shrinking Majuli river island, and an unresolved citizenship- registration debate dating to the 1985 Assam Accord.

India's National Capital Territory is a city-state unlike any other in the country: a seat of national government, a 3,000-year-old settlement layered with seven historic cities, and one of the most densely populated, economically productive, and environmentally stressed urban regions on Earth.

Delhi's per-capita incomeAverage income per person — total income (often GSDP) divided by population. of ₹5,12,131 (2023-24) is roughly 2.4 times India's national average — yet nearly half its population still lives in slums or unauthorized colonies without full civic amenities.

Delhi sits on the Indo-Gangetic plain straddling the Yamuna River, bordered by Haryana on three sides and Uttar Pradesh to the east. It became a Union Territory in 1956 and gained special National Capital Territory status with its own legislature in 1991-92. Governance is split between the Delhi government (NCTNational Capital Territory — Delhi's official administrative status, granting it its own legislature while central government retains control of law, order, and land.), the Municipal Corporation of Delhi, the New Delhi Municipal Council, and the central government, which retains control of law and order and land — a layered structure examined in detail in Chapter 03 and that shapes nearly every policy challenge covered later in this report. Administratively, Delhi is organized into 13 districts as of January 2026 (up from 11), reflecting continued urban expansion and administrative reorganization roughly every decade since the 1970s.
