Sikkim is an enigma for most, its history and its 1975 merger with India shrouded in mystery. This book fills the lacunae on both fronts, combining insights into the erstwhile royal kingdom's unique history with the intriguing story of how it became India's twenty-second state. It examines the often-fraught relationship between its original inhabitants, the Lepchas, and the Bhutias (people of Tibetan origin) who established institutions of religion and governance - Lamaist Buddhism and the Namgyal dynasty respectively.

Aspects of the Indian relationship with Tibet form part of this narrative, in particular due to the British involvement in the Himalayan region as a consequence of the 'Great Game' and great power rivalry with the Russian empire. For India today, Sikkim remains significant from a strategic point of view, given its proximity to the border with Tibet, now China, and the presence of the vital Siliguri Corridor that connects India's northeast with the rest of the country.
