International Expositions, often called World Expos, are large-scale public exhibitions that showcase the achievements of nations. These events typically occur every few years and last for several months, featuring pavilions from various countries that highlight their culture, technology, and innovations. The themes of these expositions can vary widely, focusing on topics like sustainability, urban development, or cultural exchange. The first recognized International Exposition was the Great Exhibition held in London in 1851. Since then, many notable expositions have taken place, including the Expo 67 in Montreal and the Expo 2020 in Dubai. These events aim to foster international cooperation and promote global dialogue on pressing issues.
