Seven Sisters of India: States, Capitals and Key Facts

The Seven Sisters of India are the seven contiguous states of Northeast India: Arunachal Pradesh, Assam, Manipur, Meghalaya, Mizoram, Nagaland and Tripura. Together with Sikkim, often called the “brother”, they form the Northeast region. These states are linked to the rest of India through a narrow strip of land in West Bengal known as the Siliguri Corridor.

The nickname is popular, but many people are unsure where it came from or what it includes. This guide explains the origin of the term, lists each state with its capital and key facts, and shows how the Seven Sisters of India differ from one another.

Key takeaways

  • The Seven Sisters are Arunachal Pradesh, Assam, Manipur, Meghalaya, Mizoram, Nagaland and Tripura.
  • Sikkim joined the North Eastern Council in 2002 and is often called the “brother”.
  • The name was popularised in 1972 by journalist Jyoti Prasad Saikia.
  • Most of the region’s boundary is an international border with China, Myanmar, Bangladesh, Bhutan and Nepal.
  • The states share geography but differ greatly in language, culture and history.

Why are they called the Seven Sisters of India?

The name “Land of the Seven Sisters” was coined in January 1972 by Jyoti Prasad Saikia, a journalist from Tripura. He used it during a radio talk show, around the time Manipur, Meghalaya and Tripura became full states.

He later expanded the idea into a book. The name stuck because it captured two things at once. The states are closely linked by geography and history. At the same time, each has its own distinct identity, much like siblings in a family.

Sikkim, the eighth Northeast state, has Gangtok as its capital. It became part of India in 1975.

How the Seven Sisters were formed

At independence, much of today’s Northeast was part of the large state of Assam. Over the following decades, new states were carved out to reflect the region’s diverse communities.

  1. Nagaland became a state in 1963, the first to be separated from Assam.
  2. Manipur, Meghalaya and Tripura became full states in January 1972.
  3. Arunachal Pradesh and Mizoram became states in February 1987.

Arunachal Pradesh was earlier known as the North-East Frontier Agency (NEFA). It became a Union Territory in 1972 and a full state in 1987.

Sikkim: the brother of the Seven Sisters

Sikkim is not one of the Seven Sisters. Instead, it is often called their “brother”. It became part of India in 1975 and was added to the North Eastern Council in 2002.

Geographically, Sikkim is separated from the other seven states. It sits in the eastern Himalayas between Nepal, Bhutan and China. Nevertheless, it shares many cultural and developmental links with the rest of the region.

The Seven Sisters of India connect to the rest of the country through the Siliguri Corridor in West Bengal. At its narrowest, this strip is only about 20–22 km wide. Because of its shape, it is often called the “Chicken’s Neck”.

Road, rail, pipelines and power lines all pass through this corridor. As a result, it is one of the most strategically important areas in India.

Borders of the Seven Sisters

Northeast India shares long international borders. In fact, the vast majority of its boundary touches other countries.

What makes each of the Seven Sisters different?

Each state has a distinct character. Here is a quick snapshot:

  • Assam is known for tea, the Brahmaputra and Kaziranga’s one-horned rhino.
  • Arunachal Pradesh is the largest state in the region, home to Tawang and dozens of tribes.
  • Manipur is famous for Loktak Lake, classical Manipuri dance and polo.
  • Meghalaya has living root bridges and some of the wettest places on Earth.
  • Mizoram has one of the highest literacy rates in India.
  • Nagaland is home to many Naga tribes and the Hornbill Festival.
  • Tripura has royal palaces such as Ujjayanta Palace and Neermahal.

Travelling across the Seven Sisters of India

Four of the seven states require an inner line permit for Indian visitors: Arunachal Pradesh, Nagaland, Mizoram and Manipur. Assam, Meghalaya and Tripura do not.

Guwahati in Assam is the main gateway, with the region’s busiest airport and railway station. From there, roads fan out to Shillong, Tawang, Kohima and beyond. To plan your dates, see our guide to the best time to visit Northeast India.
