History is the study of past events, particularly in human affairs. It helps us understand how societies, cultures, and civilizations have evolved over time. By examining artifacts, documents, and oral traditions, historians piece together narratives that explain how people lived, what they believed, and how they interacted with one another. Key periods in history include the Ancient Civilizations, the Middle Ages, and the Modern Era. Each of these periods is marked by significant developments, such as the rise of empires, technological advancements, and social changes. Understanding history allows us to learn from past mistakes and successes, shaping our present and future.
