This introduction presents an overview of key concepts discussed in the subsequent chapters of this book. The book argues that the boundary commission headed by Cyril Radcliffe offers a window into the complexity of nationalist dealings with colonial power structures and of colonial strategies of control, even during decolonization. It examines the nature of power relationships within the colonial state, with a focus on the often-veiled exertion of British colonial power. The book traces the reluctant cooperation of South Asian elites with British leaders in setting up the Radcliffe commission. It focuses on partition's impact on Punjab, in the north-west wing of the South Asian subcontinent. The book also focuses on the high politics of the British withdrawal and of Indian and Pakistani independence. It deals with the ground-level impact of the partition process.
