The Panama–Pacific International Exposition was a world's fair held in San Francisco, California, United States, from February 20 to December 4, 1915.

Its stated purpose was to celebrate the completion of the Panama Canal, but it was widely seen in the city as an opportunity to showcase its recovery from the 1906 earthquake.

[2] The 1915 American Grand Prize and Vanderbilt Cup auto races were held February 27 and March 6 on a 3.84-mile (6.18 km) circuit set up around the Exposition grounds.

The most popular attraction at the exposition that depicted Native American life is James Earle Fraser's statue The End of the Trail.

[6] These celebrations over the Native community, can be seen through artworks such as The End of the Trail and The Pioneer or tributes to Francisco Pizarro and Hernán Cortés.

[5] In comparison to previous world fairs, the Panama–Pacific International Exposition showcased Native Americans more as nobles rather than savage people, but who were still inevitably destined to become extinct.

In efforts to promote the fair, organizers used the "New Woman" as an advertising tactic and proof that San Francisco was an evolving and safe environment for tourists.

Constructed from temporary materials (primarily staff, a combination of plaster and burlap fiber), almost all the fair's various buildings and attractions were pulled down in late 1915.

[19][20] The Legion of Honor Museum, in Lincoln Park, was the gift of Alma de Bretteville Spreckels, wife of the sugar magnate and thoroughbred racehorse owner/breeder Adolph B.

[22] The warehouse for the exposition was moved to Fort Hunter Liggett in South Monterey County and the structure, nicknamed the "Tin Barn", has served as the base fire department for the last 30 years.

[23][24] The US Post Office issued a set of four postage stamps to commemorate the exposition, with designs depicting a profile of Vasco Núñez de Balboa (1¢), the Pedro Miguel Locks of the Panama Canal (2¢), the Golden Gate (5¢), and the discovery of San Francisco Bay (10¢).

[25][26] The United States Congress authorized the San Francisco Mint (also known as "The Granite Lady") to issue a series of five commemorative coins.

[28] In 2015, the California Historical Society, the Maybeck Foundation, and Innovation Hangar partnered with the City and County of San Francisco to commemorate the centennial of the transformative 1915 Panama Pacific International Exposition.

[29] On June 20, 2015 a commemorative orchestra, chorus and band concert was held at the Palace of Fine Arts to celebrate the 100th anniversary of the fair.

A feature film, When the World Came to San Francisco, which tells the story of the fair, was made by writer and director R. Christian Anderson.
