World History — Global Civilizations, Modern Revolutions & World Wars

World history traces the overarching trajectory of human civilizations, political transformations, and intellectual revolutions that have shaped modern global society. Beginning with river valley settlements in Mesopotamia, Egypt, and the Yellow River, early human organization evolved through the philosophical and imperial achievements of classical Greece and the Roman Republic and Empire. The European Renaissance and Scientific Revolution dismantled feudal paradigms, paving the way for the Industrial Revolution and epochal political transformations in the American Revolution of 1776 and French Revolution of 1789 that championed democracy, liberty, and the modern nation-state. The twentieth century was defined by the catastrophic global conflicts of World War I and World War II, the dismantling of colonial empires through decolonisation, and the geopolitical ideological struggle of the Cold War.
