The document provides a history of tourism from ancient times to the modern era. In early history, travel was primarily for trade, food, or escaping danger. The Egyptians, Persians, Greeks, and Romans helped develop travel infrastructure and make travel more common for both necessity and pleasure. During the Renaissance, the Grand Tour emerged where young European men would travel to major cities to broaden their education. Thomas Cook is considered the Father of Tourism, organizing the first package tours in the mid-1800s and making travel arrangements easier. Key developments in the 20th century that expanded tourism included the advent of air travel, the jet age, and establishment of international tourism organizations.
