The Klondike Gold Rush had made Seattle the dominant city in the Pacific Northwest, being the major source of supplies to Alaska. The goal of the 1909 Alaska-Yukon-Pacific Exposition was to show off the growth and development of the Pacific Northwest, specifically Seattle, and to display the value of commercial trade with the Pacific Rim. When Japan agreed to participate, the AYPE became a truly international, multi-cultural event, which planners of the AYPE hoped would demonstrate cooperation between people from around the world. City officials also hoped that the exposition would encourage people to relocate to the growing metropolis of Seattle.

The location needed to demonstrate the beauty of the region. Officials soon decided on the largely wooded grounds of the University of Washington, situated on Lake Washington, with Mount Rainier visible in the distance. The first $650,000 for the AYPE was raised by proud Seattleites, who bought “shares” of the exposition. Much of the rest was funded by the sale of public lands and by the Washington State legislature, with the understanding that the buildings built for the exposition would become part of the University of Washington at the end of the AYPE. John and Frederick Olmsted, son and stepson of Frederick Law Olmsted, prominent landscape architects in their own right, designed much of the AYPE grounds.

Thanks to the two years of planning and the huge sums of money raised, the AYPE grounds and exposition were everything the planners had hoped for. It was a fascinating mix of ethnic diversity and crass commercialism, but it clearly appealed to the people of the United States. Over 80,000 people attended the AYPE on opening day in June 1909, and by closing day (October 16, 1909) 3.7 million people had paid to see attractions such as the Igorrote Village, and the Indian and Eskimo exhibits. They had seen animals built out of fruits and nuts, and rode on the Fairy Gorge Tickler. The AYPE had been a huge success. Seattle officials were pleased to note that the AYPE had drawn 700,000 people more than the 1905 Lewis and Clark Exposition had attracted in the rival city of Portland, Oregon.
