A Universal Exposition, also known as a World’s Fair, is a large international exhibition designed to showcase the achievements of nations. These events often feature pavilions from different countries, highlighting their culture, technology, and innovations. The first Universal Exposition took place in 1851 in London, known as the Great Exhibition, and set the standard for future fairs. Universal Expositions are held every few years in various cities around the world, with themes that reflect global issues or advancements. Notable examples include the 1893 World's Columbian Exposition in Chicago and the 1967 Expo 67 in Montreal. These events promote cultural exchange and inspire progress.
