What is the history and meaning of the Illinois State Flag?

The Illinois state flag features the Great Seal of Illinois on a white background, symbolizing the state’s history, unity, and balance between state and national authority. A bald eagle represents the United States, holding a banner with the motto “State Sovereignty, National Union,” reflecting Illinois’ role within the federal system. The shield honors the original 13 colonies, while the prairie soil, rock, and rising sun over Lake Michigan represent strength, fertile land, and new beginnings. The state name and official colors were added in 1970 to improve recognition and consistency.
