This book aims to provide a concise yet comprehensive picture of international developments from the end of World War II in 1945 to the dissolution of the Eastern Bloc and the Soviet Union in 1991.

The study is articulated around three main axes: the Cold War, decolonization, and the rise of the Third World, as well as European integration. At the same time, the different schools of international literature on certain issues (such as the onset of the Cold War or decolonization) are presented briefly, along with attempts to assess the influence of key figures: Stalin, Kennedy, Kissinger, de Gaulle, Gorbachev.

The post-war period is particularly fascinating regarding diplomatic, political, and economic developments, the organization of international society, and even the ideological ferment. Adequate knowledge of this period is essential for understanding the ongoing dynamics in the next period, which we are living in today: the post-war world, a subject worthy of systematic and responsible historical study, continues to be ever-present in our lives.
