The Alaska Yukon Pacific Exposition, held during the summer of 1909, was the first "world's fair" held in Seattle. Capitalizing on the popularity of the booming gold rush, the exposition was designed to showcase the riches of the Pacific Northwest and highlight trade with the Pacific Rim nations and beyond. Millions of visitors came to Seattle to experience the one-of-a-kind attractions, exhibits, and events held during the AY PE, which became the footprint for the modern University of Washington campus. Many of these visitors stayed to populate the growing metropolis. From the ornate European-style architecture to the fountains and gardens, the amusements of the Pay Streak, and the exotic Oriental exhibits, the AYPE entertained and educated while bringing needed business to Washington State.
