The Florida Stage flag is: State Flag
The current design of Florida’s state flag was adopted in 1900. In that year, Florida voters ratified a constitutional amendment based on an 1899 joint resolution of the state legislature to add diagonal red bars, in the form of a St. Andrew’s cross, to the flag.
Between 1868 and 1900, Florida’s state flag consisted of a white field with the state seal in the center. During the late 1890s, Governor Francis P. Fleming suggested that a red cross be added, so that the banner did not appear to be a white flag of truce or surrender when hanging still on a flagpole.
In the rewriting of the Constitution in 1968, the dimensions were dropped and became statutory language. The flag is described in these words: “The seal of the state, of diameter one half the hoist, in the center of a white ground. Red bars in width one fifth the hoist extending from each corner toward the center, to the outer rim of the seal.”
