In the Eastern Himalayas, Sikkim's history is shaped by the Bhutias, Lepchas, and Limbus. The Lho-Men-Tsong-Sum treaty recognized these as the original inhabitants, but the Limbus have faced challenges, including losing their legislative seat in 1973, sparking a fight for recognition. This book chronicles the Limbus' unwavering struggle to assert their claims, secure rights, and preserve their culture. Navigating politics, they have leveraged activism to maintain their status as one of Sikkim's indigenous pillars. The Forgotten Pillar explores their quest for autonomy and the broader implications for indigenous communities in India.
