The name Carol 2 is a Romanian form of Carolus. This form was historically used by two kings of Romania: Carol I (1839–1914), the first king of the Romanian Principality, and Carol II (1893–1953), his grand-nephew. Carol I was a Hohenzollern prince who helped modernize the country, while Carol II's reign was marked by political turmoil and eventual abdication. The name thus carries royal associations within Romanian history.
