North Carolina was established as a royal colony in 1729 and is one of the original Thirteen Colonies. North Carolina is named in honor of King Charles I of England who first formed the English colony, with Carolus being Latin for "Charles". On November 21, 1789, North Carolina became the 12th state to ratify the United States Constitution. North Carolina declared its secession from the Union (American Civil War) on May 20, 1861, becoming the last of eleven states to join the Confederate States. Following the Civil War, the state was restored to the Union on June 25, 1868. On December 17, 1903, Orville and Wilbur Wright successfully piloted the world's first controlled, sustained flight of a powered, heavier-than-air aircraft at Kill Devil Hills in North Carolina's Outer Banks. North Carolina uses the slogan "First in Flight" on state license plates to commemorate this achievement.
