Introduction
The flag of Illinois is a state seal on a white field design, a common pattern among U.S. state flags. Its most prominent feature is a detailed rendition of the Great Seal of the State of Illinois, centered on a pure white background. Below the seal, the state's name, 'ILLINOIS', is inscribed in bold, blue capital letters.
The flag's design is anchored by the official state seal, which is rendered in multiple colors including shades of brown, gold, blue, and red. The seal itself is complex, depicting a bald eagle perched on a rock holding a shield in its talons. A key visual element is the red, white, and blue shield with thirteen stars and stripes, symbolizing the original colonies.
A distinctive date, '1818', appears on the seal's rock, marking the year of Illinois' statehood. A later addition to the flag's design, the date '1868' is also present on the scroll in the eagle's beak, commemorating the year the state seal was first used. The overall impression is one of heraldic complexity set against a simple, unadorned white field.
Meaning & Symbolism
The central bald eagle represents the United States, with the shield in its talons symbolizing the state's defense of the Union. The shield's design, featuring thirteen stars and stripes, directly references the nation's original colonies and the American flag. In its beak, the eagle holds a red scroll with the state motto, 'State Sovereignty, National Union', though the word 'Sovereignty' appears upside down relative to 'Union'.
The prairie landscape in the background, with the rising sun over a lake, signifies the state's location and promising future. The date '1818' on the rock marks the year Illinois joined the Union. The white field of the flag has no specified symbolic meaning but serves to highlight the colorful seal.
History of the Illinois Flag
The first official state flag was adopted on July 6, 1915, following a design competition won by Lucy Derwent. This original flag featured the state seal on a white field but did not include the state name. For over fifty years, this was the official banner of Illinois.
In 1969, Chief Petty Officer Bruce McDaniel petitioned to modify the flag, arguing that without the state's name, it was unrecognizable. The Illinois General Assembly subsequently added the word 'ILLINOIS' in blue letters beneath the seal. This revised design, incorporating the state name, became the official flag on July 1, 1970, and remains in use today.
Curiosities
- The word 'Sovereignty' on the state seal's scroll is famously placed upside down relative to 'Union', a unique and often-discussed design quirk.

- The flag's design is governed by specific statutes in the Illinois Compiled Statutes (5 ILCS 465/), which detail its official appearance and use.
