The book delves into the status of three regions: Kashmir, Sikkim, and the province of Assam in 1947. In Kashmir, Sheikh Abdullah had emerged as a charismatic leader before it was raided by Pakistan. It also explores how Sikkim was accorded the status of an India-protectorate state in 1950. The Naga National Council, led by Z.A. Phizo, resorted to armed uprisings in 1950’s in Naga Hills, followed by M.N.F. and Laldenga thereafter. The book sheds light on the dynamics of collaboration and rebellion involving leaders like Sheikh Abdullah, and last King of Sikkim, P.T. Namgyal, with the Indian establishment and why and how did they rebel against them. Additionally, it discusses consequences of these tribal leaders’ armed resurrection, and their role in the formation of Nagaland and Mizoram as Indian states. This book, which offers a unique perspective on the historical evolution of these regions, will be invaluable for Indian policymakers to view the Indian Union from the perspectives of the Frontier leadership.
