In 1812 Louisiana became the eighteenth state to join the Union. The state flag originated with an 1800 design but was officially adopted by the Louisiana State Legislature in 1912. On a field of solid blue is displayed the state bird, the eastern brown pelican, from the state seal. The mother pelican is shown tearing flesh from her own breast to feed her three young. Louisiana's motto—"UNION, JUSTICE and CONFIDENCE"—is printed in blue letters on a white and gold banner below the pelicans.
