India has a multi-dimensional relationship with the Federal Republic of Germany, which is its largest trading partner within the European Union, a major source and destination of foreign direct investment, a significant donor, and an important source of technology. This timely and in-depth book examines the evolution and expansion of India's economic, political, defence, and scientific-technological relationship with Germany from 1947 to the present day. It analyses mutual perceptions, highlights the elements of convergence and divergence, and discusses the challenges and prospects in a world that is in geopolitical flux and disarray. The book argues that India and Germany have an incrementally increasing relationship with more overlapping than conflicting interests. Drawing on extensive English and German language source material, including declassified documents of the German Foreign Office, and interviews with past and present policy-makers/stakeholders, this volume fills a long-felt gap in existing literature.
