World Exhibitions, also known as World Fairs, are large international events that showcase the achievements of nations in various fields, including technology, culture, and art. These exhibitions provide a platform for countries to present their innovations and share ideas with the global community. They often feature pavilions representing different nations, where visitors can explore exhibits and participate in cultural activities. The first World Exhibition, the Great Exhibition, took place in London in 1851. Since then, these events have been held in various cities around the world, typically organized by the Bureau International des Expositions (BIE). Each exhibition has a specific theme, encouraging countries to collaborate and inspire progress in areas such as sustainability, education, and urban development.
