Queen Anna is one of the main protagonists of Disney's Frozen franchise. She is the second-born daughter of King Agnarr and Queen Iduna, the younger sister of Elsa the Snow Queen, and the contemporary ruler of Arendelle. 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.
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, who is the female protagonist of the Hans Christian Andersen fairy tale, "The Snow Queen".
