The term 'Seven Sisters' was first used by journalist Jyoti Prasad Saikia in the context of a radio talk in 1972, when the states were reorganised in Northeast India. The name reflects:

1. Geographical interdependence: All seven states are largely surrounded by international borders (China, Myanmar, Bangladesh, Bhutan) and are connected to mainland India only through the Siliguri Corridor — a narrow land strip in West Bengal, only about 20–22 km wide at its narrowest point. This means the states depend on each other and on this single corridor.

2. Shared characteristics: They share similar terrain (hilly/mountainous), climate (humid subtropical to alpine), biodiversity (Northeast India is a global biodiversity hotspot), and many tribal cultures.

3. Historical links: Before 1947 and the subsequent reorganisation, these areas were part of Assam or administered as a single unit.

4. Sisterly bond: Like sisters in a family, these states are close, interdependent, and inseparable despite having distinct identities.

Sikkim is often referred to as the 'brother' (or sometimes 'eighth sister') of the Seven Sister States: • Sikkim became India's 22nd state on 16 May 1975 after a referendum. • It shares geographic proximity and cultural links with the seven sisters. • Capital: Gangtok. • Located in the Eastern Himalayas. • Borders Nepal, Tibet (China), and Bhutan. • Known for Kangchenjunga, the world's third-highest peak (8,586 m). • Sikkim was the first organic state in India (100% organic farming). • It is not technically a 'seven sister' because it is geographically separated from the group (it does not share a border with most of them) and has a different political history. It is connected to the northeast corridor but stands apart in culture and history.

Northeast India (the Seven Sisters + Sikkim) is one of the world's most significant biodiversity hotspots:

Flora: • The region has over 5,000 flowering plant species. • Rich in orchids — Arunachal Pradesh and Sikkim are orchid capitals. • Dense tropical and subtropical forests.

Fauna: • One-horned rhinoceros: Kaziranga, Assam (largest population in the world). • Golden langur, Hoolock gibbon (only ape in India), clouded leopard. • Snow leopard in higher elevations of Arunachal Pradesh and Sikkim. • Keibul Lamjao (Manipur): world's only floating national park — home to the endangered Sangai deer (brow-antlered deer).

Tribal Cultures: • Over 220 scheduled tribes live in Northeast India. • Each state has its own distinct tribal languages, dances, festivals, and traditions. • Major tribes: Naga (Nagaland), Mizo (Mizoram), Khasi/Garo (Meghalaya), Bodo (Assam), Ao (Nagaland), Meitei (Manipur). • Hornbill Festival (Nagaland, December), Bihu (Assam), Chapchar Kut (Mizoram), Sangai Festival (Manipur) are major festivals.
