The 1909 Alaska-Yukon-Pacific Exposition was held in Seattle on the University of Washington campus from June 1 to October 16. This was Washington's first world's fair and it celebrated 12 years of prosperity -- since the 1897 Alaska Gold Rush -- through the display of resources, products, and advantages of Washington and the region. More than three million people visited the fair from Washington cities and counties and from the rest of the country. Throughout the exposition, commemorative days were set aside to honor organizations, professions, and ethnic communities, as well as visitors from various cities, counties, and states. Some of these commemorations included banquets, conferences, or other forms of special recognition given to the groups being honored. Because these events were so popular with fairgoers, A-Y-P promoters kept adding new commemorative days as the fair progressed. Thus, some days had multiple honorees. Following is a list of all A-Y-P commemorative days as reported in The Seattle Daily Times, The Seattle Sunday Times, and the Seattle Post-Intelligencer.
