The flags of the U.S. states, territories, and the District of Columbia exhibit a variety of regional influences and local histories, as well as different styles and design principles. Nonetheless, the majority of the states’ flags share the same design pattern consisting of the state seal superimposed on a monochrome background, commonly a shade of blue, which remains a source of criticism from vexillologists. The most recently adopted state flag is that of Mississippi, adopted on January 11, 2021, while the most recently adopted territorial flag is that of the Northern Mariana Islands, adopted on July 1, 1985.
History
Modern U.S. state flags date from the turn of the 20th century, when states considered distinctive symbols for the 1893 World’s Columbian Exposition in Chicago, Illinois. Most U.S. state flags were designed and adopted between 1893 and World War I.
According to a 2001 survey by the North American Vexillological Association, New Mexico has the best-designed flag of any U.S. state, U.S. territory, or Canadian province, while Georgia‘s state flag was rated the worst design (Georgia adopted a new flag in 2003; Nebraska’s state flag, whose design was rated second worst, remains in use).
