The oldest known monarchs of Arendelle were King Agnarr and Queen Iduna. On winter solstice, Iduna would give birth to Elsa, who was gifted with the ability to control ice and snow. Three years later, on summer solstice, Iduna would have her second child, Anna, who lacked any magical abilities.
Due to the unstable nature of Elsa's powers and until Elsa could learn to control her winter magic, the castle was closed off for 13 years following the king's orders; this was done for Elsa's safety, as well as the safety of Anna.
During Elsa and Anna's teenage years, Agnarr and Iduna perished in a storm at sea.
On the day of Elsa's coronation, when her magical abilities were unintentionally exposed to the public by Anna, Elsa accidentally sets off an eternal winter upon running away that froze the kingdom. While Anna searched for Elsa who had traveled into the mountains, Hans took on the task of protecting the kingdom.
Unbeknown to either Anna or Elsa, Hans had hidden agendas to eventually usurp the throne to rule as king. After Elsa's incarceration as punishment for her curse, and Anna's supposed death as a result of a curse accidentally inflicted by Elsa, Hans became the illegitimate king consort of Arendelle, fooling the citizens into believing he and Anna married prior to her death, leaving the kingdom in his hands.
Towards the end of the film, thanks to Anna's efforts and love for her sister, Elsa found the courage to undo the eternal winter and peace was restored to the kingdom; Hans was sent back to his homeland to face punishment for his actions of treason against the princess and queen, trade was cut with the neighboring kingdom of Weselton as their duke led an assassination plot against Elsa during the eternal winter, and Elsa regained her position as reigning monarch.
The time period for Frozen is set in July 1839. In the upper left-hand corner of the geographical map shown in Frozen Fever, it is suggested by a set of roman numerals that the year in which Anna turned nineteen was 1840. (MDCCCXL is the exact numeral order.) Oaken's statement, "A real howler in July, yes?", confirms the month being set in July. This being said, given that Anna is eighteen as of the events of Frozen, it can be logically assumed that Frozen takes place in July 1839.
The official crest of Arendelle is the crocus, appearing on various items within the kingdom such as banners, capes, flags, uniforms, wallpaper, clothing and jewellery. The colors green and purple, and to a lesser extent yellow, are associated and prominent with the kingdom of Arendelle. Crest designs usually encompass the golden yellow stylized crocus, emblazoned on a background that is purple on the left half and green on the right half. On Elsa's profile banner, the purple left half of the background is darker, and the right half is a darker yellow.
Places of interest
- Arendelle Castle: The home of the royal family of Arendelle.
- Arendelle Chapel: The chapel in which Elsa's coronation ceremony took place.
- The village: The village outside the castle gates, filled with various homes, shops, a marketplace, the docks, and a clock tower. It is also where the citizens of Arendelle reside.
- The name 'Arendelle' is based on the Norwegian town of Arendal, located in the county of Aust-Agder, to the southwest of the Norwegian capital, Oslo. However, the scenery of Arendelle is based primarily on Nærøyfjord in western Norway, as well as various buildings in Oslo, Bergen, and other Norwegian cities.
- Arendelle's name is also similar to that of Arundel, an English market town and civil parish in a steep vale of the South Downs, West Sussex. The name was spelled 'Arundell' until 1733, when the final l was dropped. Arundel is home to Arundel Castle, seat of the Duke of Norfolk; and to Arundel Cathedral, seat of the (Catholic) Bishop of Arundel and Brighton.
- In Norwegian, 'Aren' is possibly derived from 'ørn', which means "eagle", and 'delle' is derived from 'dal', which means "valley".
- The crocus is a symbol of rebirth and spring. In cold regions, the flower blooms while snow is still on the ground.
- The eternal winter Elsa caused may be a representation about how in the northern reaches of Norway winter will last anywhere from 8–10 months.
- Reading further into the meaning of this kingdom's name, it's interesting to note that Walt Disney's own great-grandfather was named Arundel Disney.
- In the film Big Hero 6, a ship from Arendelle can be seen sitting in the docks.
