The flag of Louisiana consists of a rectangular field of blue with the arms of Louisiana, a pelican vulning herself, in white in the center, with a ribbon beneath, also in white, containing in blue the state motto: "Union Justice Confidence". The flag was officially adopted July 1, 1912, and is often referred to as the Pelican flag.
