WORLD HISTORY

Introduction

World History from the Industrial Revolution to the contemporary world represents a period of extraordinary transformation. This era witnessed the breakdown of old socio-political structures, the rise of new economic systems, and the spread of revolutionary ideas that reshaped every aspect of human life. The Industrial Revolution triggered profound technological, social, and economic changes, which in turn fuelled nationalism, imperialism, and major political upheavals across Europe and beyond.

The 20th century further altered global dynamics with the outbreak of World War I and World War II, leading to redrawn borders, the fall of empires, and the emergence of new political ideologies. The interwar years, marked by economic crises and authoritarian regimes, set the stage for global conflict and long-lasting geopolitical shifts.

Following 1945, the world witnessed decolonization, the rise of the Cold War, and the emergence of two superpowers shaping international relations. The later decades were defined by globalization, technological revolutions, and increasing interconnectedness among nations.

For UPSC aspirants, understanding this period is crucial for analyzing modern geopolitics, socio-economic developments, and the evolution of contemporary global institutions. This section provides a structured and concise exploration of these transformative events and their lasting impacts.
