The Lewiston-Nez Perce County Airport serves the city by air. Lewiston was founded in 1861 in the wake of a gold rush which began the previous year near Pierce, northeast of Lewiston. In 1863 Lewiston became the capital of the newly-created Idaho Territory. Lewiston's stint as a seat of the new territory's government was short-lived however, a resolution, to have the capital moved from Lewiston to Boise, was passed by the Idaho Territorial Legislature on December 7, 1864.
