During the Spanish-American War, the First Idaho Infantry received a regimental flag with the state seal centered on a blue field. The regiment carried this flag to the Philippines in 1899.
The legislature passed an act on March 12, 1907, creating a state flag. The design honored the First Idaho Infantry by using their battle flag, replacing the regiment's name with State of Idaho. In 1957, Paul B. Evans revised the seal to add more detail. This version was approved on March 1, 1957.
