Which state is not included under the seven sisters of North-East India?

The term "Seven Sisters" is a collective name for the seven states located in the North-Eastern region of India. These states are Assam, Arunachal Pradesh, Manipur, Meghalaya, Mizoram, Nagaland, and Tripura. The term originated to highlight the unique cultural and geographical characteristics of these states, which are distinct from the rest of India.

Sikkim, while geographically located in the North-Eastern region, is not included in the Seven Sisters. Sikkim was an independent kingdom until 1975 when it became a part of India as its 22nd state. The exclusion of Sikkim from the Seven Sisters is due to its historical and political background, which differs from the other states in the region.

The Seven Sisters are known for their rich biodiversity, diverse cultures, and scenic landscapes. Each state has its own unique features and contributions to the region. For example, Assam is known for its tea gardens and one-horned rhinoceros, while Arunachal Pradesh is known for its tribal diversity and natural beauty.

Understanding the geographical and political context of the North-Eastern region is crucial for comprehending the significance of the Seven Sisters. The region is strategically important for India due to its proximity to several international borders and its role in maintaining the country's security and economic interests.

In summary, the Seven Sisters of North-East India are a specific group of states that share a common geographical and cultural identity. Sikkim, while part of the North-Eastern region, is not included in this group due to its distinct historical and political background. This distinction is important for students to understand the regional dynamics and the unique characteristics of each state in the North-Eastern region of India.
