Louisiana is a state in the Deep South and South Central regions of the United States. It is the 20th-smallest by area and the 25th most populous of the 50 U.S. states. Louisiana is bordered by the state of Texas to the west, Arkansas to the north, Mississippi to the east, and the Gulf of Mexico to the south. A large part of its eastern boundary is demarcated by the Mississippi River. Louisiana is the only U.S. state with political subdivisions termed parishes, which are equivalent to counties, making it one of only two U.S. states not subdivided into counties (the other being Alaska and its boroughs). The state’s capital is Baton Rouge, and its largest city is New Orleans. The flag of Louisiana represents the U.S. state of Louisiana. It consists of a “pelican in her piety”, the heraldic charge representing a mother pelican “in her nest feeding her young with her blood” on an azure field with state motto reworded to “Union Justice and Confidence.” First adopted in 1912, it was last modified in 2010. 4K Resolution.
