Why is north and South Carolina called Carolina?

Answer 1

The original area of Carolina - which is Latin derived and named for King Charles II of England - was all land South of Virgina and North of St. Augustine all the way to the Pacific Ocean. By the early 18th century, around 1720 it was understood by the early colonist that it was too hard to govern the area as one. So everything north of the Cape Fear River was called North Carolina and everything South of the river was called South Carolina
