The name Belle originates from the French language and is a feminine form of the French word "beau" or "bel", meaning beautiful or handsome. This name first gained prominence in the 12th century during the Middle Ages in France.

Belle was initially used as a descriptive term rather than a given name, often appearing in medieval French literature and poetry to describe a beautiful or admirable woman. Over time, it transitioned into a commonly used first name, particularly among the French nobility and upper classes.

One of the earliest recorded instances of the name Belle can be found in the 13th-century French medieval romance "Le Bel Inconnu" (The Fair Unknown), where the female protagonist is referred to as Belle. This literary work is believed to have contributed significantly to the popularization of the name.

In the 14th century, Belle emerged as a standalone given name, gracing notable figures such as Belle de Bourbon (1339-1390), a member of the French royal family. During the Renaissance period, the name gained further traction, particularly among the aristocracy and artistic circles.

Belle has been associated with several famous individuals throughout history, including:

1. Belle da Costa Greene (1879-1950), an American librarian and bibliographer who played a crucial role in developing the Pierpont Morgan Library's collection.

2. Belle Starr (1848-1889), an American outlaw and horse thief who gained notoriety in the American Old West.

3. Belle Boyd (1844-1900), a Confederate spy during the American Civil War, renowned for her intelligence and daring exploits.

4. Belle Aurore (1938-2021), a French singer and actress known for her contributions to the yé-yé pop music genre.

5. Belle Bilton (1867-1949), an English actress and singer who performed in various stage productions and pantomimes in the late 19th and early 20th centuries.

While the name Belle has retained its French roots, it has also gained popularity in various other cultures and languages, particularly in English-speaking countries, where it is often associated with beauty, grace, and charm.
