The Chicago World's Fair, officially known as the World's Columbian Exposition, took place in 1893 to celebrate the 400th anniversary of Christopher Columbus’s arrival in the Americas. It showcased innovations in architecture, technology, and culture, featuring the iconic White City with its neoclassical buildings and the first-ever Ferris wheel. The fair attracted over 27 million visitors and introduced many new products and ideas, including the electric light bulb and coca-cola. It played a significant role in establishing Chicago as a major city and influenced future world fairs with its emphasis on grandeur and public engagement.
