Held in the University District of Seattle between June 1 and October 16 of 1909, the Alaska-Yukon Exposition attracted more than four million visitors. Housed in a collection of temporary (and a scattering of permanent) structures, the exposition promoted the achievements of American industry and commerce, and comprised a range of displays highlighting agriculture, manufacturing, forestry, and a wide range of other United States businesses. The exposition's principal legacy was its contribution to the development of the University of Washington, adding four permanent buildings and a landscaped campus to an institution which, prior to 1909, had comprised a mere three buildings.
