The term "Seven Sisters" originally referred to the seven states excluding Sikkim. However, Sikkim was included in the North-eastern Council in 2002, making it officially part of the North-eastern region. Therefore, the total number of states in the North-eastern region is 8.
The North-eastern states are geographically and culturally distinct from the rest of India. They are characterized by their diverse ethnic groups, languages, and traditions. The region is also known for its rich biodiversity, with many national parks and wildlife sanctuaries. The strategic importance of the North-eastern states is significant due to their proximity to international borders and their role in India's security and economic development.
Understanding the number and names of the North-eastern states is crucial for students preparing for competitive examinations such as the UPSC Civil Services, SSC CGL, Bank PO, and State PSC. It is important to remember that Sikkim is included in the count, making the total 8 states. This knowledge helps in comprehending the geographical and cultural diversity of India, which is essential for various competitive exams and general knowledge.
