Why is Charlotte called the queen city?

It is called the queen city because it is named after Queen Charlotte Sophia, the Queen consort of the United Kingdom as the wife of King George III. She was queen during the American Revolution which resulted in the independence of the United States. The county containing the city of Charlotte, Mecklenburg County, is named for Mecklenburg-Strelitz, Queen Charlotte's birthplace in present day Germany, where her father was a duke. In "The Madness of King George" she is portrayed by academy award winning actress Helen Mirren. Charlotte, NC is the oldest and largest (by population) city in the US to bear the nickname "The Queen City" and the only one named for an actual queen.
