San Diego staged this Exposition in 1915 to celebrate the completion of the Panama Canal. San Diego would be the first American port of call north of the Panama Canal on the Pacific coast. An exposition would call attention to the city and bolster an economy still shaky from the Wall Street panic of 1907. In 1910 San Diego had a population of 39,578, San Diego County 61,665, Los Angeles 319,198, and San Francisco 416,912. San Diego’s scant population, the smallest of any city ever to attempt holding an international exposition, testified to the city’s pluck and vitality.
