Medieval/Renaissance Era:
* Snow White: Based on the Brothers Grimm fairy tale, she likely lives in a medieval German-inspired setting.
* Cinderella: Also based on a fairy tale, Cinderella's world is generally considered medieval, though with some elements of the Renaissance.
* Aurora (Sleeping Beauty): Set in a vaguely medieval, yet fantastical kingdom.
* Ariel (The Little Mermaid): While not a princess at first, she becomes one by marrying Prince Eric. Their world is a mix of medieval and Renaissance influences.
* Belle (Beauty and the Beast): Set in a slightly more modern, provincial France, likely in the 18th century.
Victorian Era:
* Tiana (The Princess and the Frog): Set in New Orleans, circa 1912, during the Jazz Age, with a strong Victorian influence.
Modern Era:
* Mulan: Based on the Chinese legend of Hua Mulan, who lived in the Northern Wei Dynasty (386–550 AD) but the film takes place in a fictionalized version of ancient China.
* Pocahontas: Set in 17th-century Virginia, but the film is based on a real historical figure and heavily romanticized.
* Jasmine (Aladdin): Set in an Arabian-inspired world, likely a fantasy setting with elements of various periods.
* Rapunzel (Tangled): Set in a fictional kingdom with a vaguely medieval look, but includes technology like lanterns that suggests a more modern setting.
* Merida (Brave): Set in medieval-inspired Scotland, with a focus on Scottish culture and traditions.
* Moana (Moana): Set in ancient Polynesia, with a focus on Polynesian culture and mythology.
* Elsa & Anna (Frozen): Set in a Scandinavian-inspired kingdom in a vaguely medieval setting, but the technology hints at a more modern time.
* Elsa (Frozen II): The sequel takes the characters to a world that appears to have ancient secrets, likely implying a time before their kingdom's founding.
Beyond the Eras:
* Rapunzel (Tangled): While her story takes place in a vaguely medieval world, Rapunzel was imprisoned for 18 years before her escape, which leaves a lot of room for her to grow up in an era of unknown technology.
* Elsa & Anna (Frozen): While the film presents a seemingly medieval setting, the characters are both skilled in magic, which could hint at a past era where magic was commonplace.
Ultimately, the era of each princess is somewhat ambiguous. While they are set in specific worlds with historical influences, the creators also take creative liberty in their portrayal of the time period.
