<![CDATA[This chapter examines the Cold War as a global ideological confrontation between the United States and the Soviet Union and analyzes its role in shaping the political, economic, and social transformation of modern Europe. Following the end of World War II, the rivalry between liberal-capitalist and socialist-communist ideologies led to the emergence of a bipolar international system that divided the world into opposing blocs. Although direct military conflict between the two superpowers never occurred, the Cold War was characterized by intense political competition, military alliances, nuclear arms races, proxy wars, and technological rivalry, particularly in the field of space exploration. This study employs a qualitative historical and library research approach by analyzing secondary data derived from academic books, peer-reviewed journals, and credible historical documents. The analysis focuses on the background, processes, and impacts of the Cold War, including its influence on European modernization, global political structures, economic development, military strategies, and technological advancements. The findings indicate that the Cold War significantly accelerated scientific and technological progress while simultaneously generating political instability, economic disparities, and prolonged regional conflicts. The chapter also discusses the collapse of the Soviet Union as a critical turning point that marked the end of the Cold War and reshaped the global order. Reforms introduced through Glasnost and Perestroika revealed structural weaknesses within the Soviet system and ultimately led to its disintegration in 1991. Overall, the Cold War and the modernization of Europe represent interconnected historical processes that have profoundly influenced contemporary international relations and global development.]]>
