Today, the flag of the state of Missouri flies in commemoration of the state’s admission to the Union on August 10, 1821 as the 26th state.

Quoting the font of all knowledge, “Designed by Mary Elizabeth Oliver, the red and white stripes represent valor and purity, respectively. The blue stripe represents the permanency, vigilance, and justice of the state. The three colors also highlight the French influence on the state in its early years.”
Also flying is the flag of Kansas City, Missouri.

The current design of this flag, adopted in 2023, retains the major element from the previous designs, but it is crisp, clear, and uncluttered.
