Queen Anna of Arendelle (pronounced Ah-na) is one of the two main protagonists of the Frozen franchise. She is the main protagonist of the 2013 film and the deuteragonist of its 2019 sequel. She is the second-born daughter of King Agnarr and Queen Iduna, the younger sister of Elsa, and the contemporary ruler of Arendelle.
Background
During their childhood, an accident involving Elsa's magic created a rift between the two sisters, leaving Anna devoid of love for many years. Despite this, Anna remained big-hearted and optimistic, albeit socially awkward. When their estrangement incidentally triggers an eternal winter, Anna embarks on a perilous journey to save her kingdom and mend the broken bond between herself and her sister.
Frozen II
Three years after her adventure, a rekindled Anna and Elsa embark on another journey to confront the elemental spirits of the Enchanted Forest. Upon their journey's end, Elsa chooses to remain in the forest as the fifth spirit, so she abdicates the throne, allowing Anna to be crowned Queen of Arendelle.
Anna is loosely based on Gerda, the female protagonist of the Hans Christian Andersen fairy tale "The Snow Queen".
