Officially Adopted: February 17, 1917
The Arizona state flag which is the official US state flag of Arizona was officially adopted on February 27, 1917, just 5 years after Arizona became an official US state.
The flag is designed in 2 halves, the top being 13 rays of red and gold, which represents the 13 original colonies of the Union and the western setting sun. The colors of the rays refer to red and yellow in the Spanish flags carried by Coronado when he came to Arizona in 1540.
The bottom half of the Arizona flag is the liberty blue in the American flag. The copper star in the center of the flag is represented because Arizona is the largest producer of copper in America. The blue and gold on Arizona’s flag are the official state colors, too!
