Oklahoma’s first flag featured a large star with the number “46” centered in the middle. The number represented the order of Oklahoma’s entry into the Union in November 1907. Mississippi did not have an official state flag prior to seceding from the Union in 1861. The new design featured a magnolia tree on the field and the Bonnie Blue flag in the canton, the first flag used by the Confederate States of America. Louisiana had unofficially used a flag similar to the current banner, a nesting pelican on a blue field. When Louisiana seceded from the Union in 1861, it officially adopted a flag with a star in the canton and a field covered by 13 red and white stripes. Maine, known as the Pine Tree State, had an eastern white pine, Pinus strobus, depicted on its first flag. A single star, representing the North Star, appeared in the canton.
