One reason for Juliana's elegant and dignified persona is its royal blood— Queen Juliana of the Netherlands had a 32-year run on the throne before abdicating in 1980. Juliana is the feminine form of Julius, the surname of an ancient Roman family (the first-century conquerer Julius Caesar was the most famous). It's said to be derived from the Latin word for "juvenile" or "youthful." An alternate meaning is from Jovilius—Jove being the king of all Roman gods.
