The central hub of Corona's kingdom was built on an island somewhere in Europe and grew over many years. The oldest known of Corona's line of monarchs is King Herz Der Sonne. During his reign, Corona was in a bitter war with their rival kingdom, Saporia. Under King Der Sonne's rule, a complex tunnel system was built beneath Corona to safely move the kingdom's knights and supplies wherever King Der Sonne needed. A detailed map of the tunnels and their secrets were recorded in a journal, by Der Sonne.
At one point, Corona was invaded by Der Sonne's sworn enemy, the ruthless General Shampanier. As her minions ravaged the kingdom, Shampanier made it to Corona Castle, where she battled Der Sonne personally. In the midst of their battle, Shampanier finds that the final pages of Der Sonne's journal contained a profession of his love, intended for her. The feelings were mutual, and the two declared their love. They were later married, and with their union brought peace between their two lands.
Centuries after King Der Sonne's reign, Corona was ruled by King Frederic's father. Eventually, Arianna became Queen atter she married Frederic who became King. During her pregnancy, Arianna became gravely ill, forcing the citizens of the kingdom to search for a fabled magic, golden flower with healing abilities. Once it was retrieved, the flower was given to Arianna, and its power saved both the queen and her daughter, named Rapunzel. Due to the flower's powers, Rapunzel was born with golden hair that also had the ability to heal the sick and injured. Because of this, a woman named Mother Gothel - who had previously hoarded the flower's power for hundreds of years to keep herself young - broke into the castle, stole Rapunzel, and hid her deep within the forest outside of Corona's reach. Rapunzel was then raised as Gothel's daughter, and her power to heal was hoarded by the witch once more. To ensure she never lost the flower's magic again, Gothel forbade Rapunzel from ever leaving the tower.
Seventeen years after her kidnapping—on the eve of her eighteenth birthday—Rapunzel met a notorious thief named Flynn Rider. With his help, she managed to escape Mother Gothel, return to Corona, and reunite with her biological parents. Rapunzel then resumes her rightful place as princess and heir to Corona's throne.

Trivia
"Corona" is the Catalan, Italian and Spanish word for "Crown".
In addition, the Bulgarian, Polish, Hungarian and Russian word is "Korona", and the Portuguese word is "Coroa".
Like the kingdom itself, the word is also associated with light and especially with the sun, describing both the faint ring visible during an eclipse and the rings of sunlight filtered through clouds.
It also comes from the constellation of the same name.
The Corona flag resembles one of the older flags of Macedonia.
In Tangled Ever After, Corona is simply called "The Kingdom".
In the Tangled: The Series episode "Queen for a Day", an old legend reveals that a demon known as Zhan Tiri had tried to destroy the kingdom with a curse powered snowstorm, as she bears a great hatred towards the kingdom. Even when the storm was ended by Lord Demanitus and had made sure that neither Zhan Tiri nor her allies could harm the kingdom again, the raging blizzard is said to return should Corona ever be at its weakest state.
As mentioned in Tangled: The Series, there are six kingdoms neighboring Corona, namely Koto, Neserdnia, Bayangor, Galcrest, Pittsford and Ingvarr. Including Corona itself, they are collectively called "The Seven Kingdoms".
In the episode "Plus Est En Vous", a satellite shot can be seen with Corona located in central France, roughly where Tours is in the real world.
Corona appears as a world in Kingdom Hearts III that is fully explorable and which events in-world follow similarly to the original Tangled film.
