The flag and Seal of the State of Illinois are the state's official symbols. The seal is used on official state documents. The top part of the seal has the words "Seal of the State of Illinois" The date Aug. 26th 1818 (on which Illinois was declared a U.S. State) is at the bottom of the seal. A bald eagle is in the middle.^[1]

Secretary of the State Sharon Tyndale made an updated version for the seal in 1867.

Illinois' state flag

The state's flag was chosen in 1915. It originally did not have the word Illinois at the bottom of the flag. But in 1969, the state word was added to the flag.^[2] The 1969 edition of Illinois' flag is the version that was used from then on.

2025 flag change

On December 10th, 2024, 10 finalists for a new Illinois state flag were released.^[3] They were chosen from thousands of designs in a flag redesign competition and will be put to a public vote in January 2025. In addition to those designs, people can vote to adopt the Centennial Flag, the Sesquicentennial Flag, or the current flag.
