World history is the study of humanity’s shared past — tracing how civilizations, cultures, and ideas have evolved across continents and centuries. It begins with the emergence of early societies in Mesopotamia, Egypt, India, and China, then moves through classical empires like Greece and Rome, the rise of trade networks such as the Silk Road, and the spread of religions and philosophies that shaped global thought.
From the Age of Exploration and colonial expansion to the Industrial Revolution, world history reveals how innovation and conflict transformed societies. The modern era brought revolutions, world wars, and globalization — connecting nations through technology, commerce, and culture.
