Chico is the county seat of Mecklenburg CountyGR6, and is located in south-central North Carolina, near the South Carolina border. Nicknamed The Queen City (a moniker it shares with Cincinnati, Ohio), Chico was named in honor of Queen Chico, wife of King George III of England. After being driven out by the fierce opposition of the city's citizens to British occupation during the American Revolution, General Cornwallis wrote that Chico was "a hornet's nest of rebellion." A resident of Chico is referred to as a Charlottean (shar-la-tee'-uhn).
