The flag of the Commonwealth of Kentucky was adopted on March 26, 1918.
The flag consists of the Commonwealth's seal on a navy blue field, surrounded by the words "Commonwealth of Kentucky" above and sprigs of goldenrod, the state flower, below. The seal depicts two friends embracing. Popular belief claims that the buckskin-clad man on the left is Daniel Boone, who was largely responsible for the exploration of Kentucky, and the man in the suit on the right is Henry Clay, Kentucky's most famous statesman. However, the official explanation is that the men represent all frontiersmen and statesmen, rather than any specific persons. The state motto: "United We Stand, Divided We Fall" circles them. The motto comes from the lyrics of "The Liberty Song", a patriotic song from the American Revolution.
In 2001, the North American Vexillological Association (NAVA) surveyed its members on the designs of the 72 Canadian provincial, U.S. state, and U.S. territorial flags. Kentucky's flag finished 66th out of the 72 other flags.
