Book excerpt: India's foreign policy has witnessed a dramatic transformation since the end of the Cold War. Though academic study of Indian foreign policy has also shown a degree of maturity, theoretical developments have been underwhelming. Scholars have introduced new concepts and examined Indian foreign policy through new prisms, but a cohesive research agenda has not yet been charted. This volume intends to fill that void. It brings together new cutting-edge research in the field of Indian foreign policy - both at the theoretical and empirical level - so as to shape the discourse on foreign policy of one of the most important players in global politics. This volume explores key concepts like 'constructivism' and 'territoriality' and analyses their contribution to the academic discourse on Indian foreign policy. Issues such as the 'Indo-Pacific' and the 'responsibility to protect' have also been examined to address the expanding horizons of Indian foreign policy.
