The Era of Cold War: Class-12th Political Science Chapter-1 ( Easy NCERT Notes )

After the end of the Second World War, the world was divided into two major power blocs led by the United States and the Soviet Union, a situation known as bipolarity which resulted in the Cold War. This chapter explains the nature of the Soviet system, the role of its leaders, and the reasons behind its collapse.

The disintegration of the Soviet Union in 1991 marked the end of bipolarity and led to the emergence of a unipolar world dominated by the United States. It also examines the consequences of this change, including new global conflicts, economic transformations, and its impact on countries like India.
