Class 12 Political Science - BIHAR
The Cold War Era
The Cold War Era chapter in Class 12 Political Science explores the global rivalry between the USA and the USSR that dominated international politics after World War II. Unlike a traditional hot war, this conflict was fought through ideological clashes, proxy wars, economic competition, and the constant threat of nuclear devastation without direct military engagement between the superpowers. Students learn about the emergence of two power blocs, the Non-Aligned Movement (NAM) as an alternative for newly independent nations, and key arms control treaties. This chapter is vital for BSEB board exams as it forms the foundation of contemporary world politics.
