Idaho State Flags

History of the Idaho State Flag

Idaho adopted its state flag in 1907. The flag displays the Great Seal on a blue field and includes a red-and-gold banner bearing the words “State of Idaho.” Emma Edwards Green’s seal design was adopted in 1891; the legislature authorized its revision in 1957. The seal represents Idaho’s people and natural resources, including mining, agriculture and forestry. Idaho’s state motto, “Esto Perpetua,” means “Be Eternal.”
