A time period refers to a specific duration in history characterized by particular events, developments, or cultural phenomena. For instance, the Renaissance was a time period marked by a revival of art and learning in Europe, spanning roughly from the 14th to the 17th century. Understanding time periods helps us contextualize historical events and societal changes. The Industrial Revolution, which began in the late 18th century, transformed economies and lifestyles, leading to the modern world we know today. Each time period has its unique features that shape the course of history.
