What is the 22nd state of India

Sikkim became the 22nd state of India when it joined the Indian Union on May 16, 1975. Previously an independent monarchy and later a protectorate, Sikkim's merger with India followed a referendum in which the majority of Sikkimese people voted for full integration. The 36th Amendment to the Indian Constitution formalized this transition, making Sikkim a full state with representation in Parliament and its own state legislature.

This historic integration expanded India's northeastern frontier and brought a culturally distinct Himalayan region into the national fold. Sikkim's accession is particularly significant in understanding India's territorial evolution in the post-independence era, as it represents one of the few instances where an independent political entity peacefully joined the Indian federation through democratic means. Today, Sikkim functions as a fully integrated state with its own government, contributing to India's strategic positioning in the eastern Himalayas while maintaining its unique cultural identity, Buddhist heritage, and environmental conservation policies.
