The name Julie originates from the Latin name Julia, which itself is derived from the ancient Roman family name Julius. The Julius family was one of the most prominent patrician families in ancient Rome, and the name is believed to have originated from the word "ioulos" meaning "downy-bearded" or "related to the god Jupiter".

In ancient Rome, the name Julia was borne by several prominent women, including Julia, the daughter of the Roman emperor Augustus and his wife Livia. Julia lived from around 39 BC to 14 AD and was known for her beauty and intelligence, but also for her scandalous love affairs.

Another famous Julia was Julia Domna, the wife of the Roman emperor Septimius Severus, who lived from around 170 AD to 217 AD. She was known for her patronage of literature and philosophy and was highly influential in the imperial court.

The name Julie gained popularity in France during the Middle Ages, where it was spelled "Julie" or "Julie". One of the earliest recorded examples of this spelling is Julie de Montmorency, a French noblewoman who lived from around 1292 to 1315.

During the Renaissance, the name Julie became associated with literary figures, such as the character Juliette in William Shakespeare's play "Romeo and Juliet", written around 1595. This helped to further popularize the name across Europe.

In more recent history, some notable people named Julie include Julie d'Aubigny (1670-1707), a French opera singer and swordswoman known for her daring exploits, Julie de Lespinasse (1732-1776), a French writer and salonist, and Julie Récamier (1777-1849), a French socialite and patron of the arts.

Other famous Julies include Julie Christie (born 1940), the British actress known for her roles in films like "Doctor Zhivago" and "Don't Look Now", and Julie Andrews (born 1935), the British actress and singer best known for her roles in films like "Mary Poppins" and "The Sound of Music".
