Ursula was banished from Atlantica primarily because of her insatiable greed and her malevolent use of dark magic, through which she attempted to usurp King Triton's rightful rule.
The Origins of Her Banishment
Originally, King Triton and Ursula were intended to rule the vast seas together. Despite this shared destiny and the specific responsibilities each was given—Triton with the mighty trident and Ursula with the magic Nautilus shell—Ursula's ambition and thirst for power led her down a treacherous path. She deviated from their intended co-rule, choosing instead to pursue personal gain and absolute control through illicit means.
Core Reasons for Her Expulsion
Her banishment from the kingdom was a direct and necessary consequence of her destructive actions, which fundamentally threatened the established order and harmony of the undersea world. The key reasons for her exile include:
| Reason for Banishment | Description |
|---|---|
| Overwhelming Greed | Ursula harbored an immense desire for power and control, far exceeding her designated role and leading her to seek dominion over the entire ocean. |
| Dark Magic Usage | She extensively utilized forbidden and malevolent magical practices, which were considered dangerous and disruptive to the natural balance of the seas. |
| Attempted Usurpation | Her ultimate and most egregious act was her attempt to unlawfully seize King Triton's throne and authority, aiming to overthrow the rightful ruler. |
Lasting Impact and Motivation
This act of banishment was not merely a punishment but also a significant turning point for Ursula. Being cast out of Atlantica ignited within her a profound and relentless desire for revenge against Triton. Furthermore, it intensified her craving for absolute power, transforming these desires into the central motivations for her future schemes and manipulative actions throughout the show.
