Forget the singing crabs and the happy, colorful wedding at sea. The original 1837 fairy tale by Danish author Hans Christian Andersen is a beautifully tragic, deeply dark story about existential dread, unrequited love, and intense physical agony. ​Here is the true, dark summary of the origin of The Little Mermaid . 1. The Deep Sea and the Eternal Soul In the ocean kingdom, mermaids enjoy a peaceful life that lasts up to 300 years. However, the Little Mermaid learns a troubling truth from her grandmother: unlike humans, mermaids do not have immortal souls. When they die, they simply turn into sea foam on the water, disappearing forever. To gain an eternal soul and enter heaven, a mermaid must win the deep love of a human man. If he marries her, a piece of his soul ties to her. This desire for a soul—and a meaningful existence—is what truly drives the mermaid to explore the surface world. 2. The Shipwreck and the Misunderstanding On her fifteenth birthday, the mermaid is finally allowed to swim to the surface. She witnesses a violent storm destroy a large ship and rescues a young Prince from drowning. She carries him safely to the shore near a temple. Before the Prince wakes up, a young woman from the temple finds him. The mermaid swims away and watches from afar. Because she had to hide, the Prince never sees her and grows up believing the woman from the temple was the one who saved his life. 3. The Deal with the Sea Witch Desperate to be with the Prince and earn a soul, the mermaid visits the Sea Witch in a terrifying part of the ocean. The witch agrees to help but demands a steep price. She brews a potion that will split the mermaid's tail into legs. The process will be terribly painful, and every step she takes on land will feel like walking on sharp needles and knives. Furthermore, if the Prince marries another woman, the mermaid will die of a broken heart the very next morning, dissolving into sea foam. Finally, the witch demands her voice as payment. She does not take it with magic; she physically cuts out the mermaid's tongue. 4. Agony and Silence on Land The mermaid drinks the potion, undergoes the painful change, and is found by the Prince. He takes her into his palace and treats her with great kindness, giving her beautiful clothes and inviting her to live there. She becomes his constant companion and even dances for him. Though she smiles, every step causes her intense physical pain, and she cannot speak or sing to tell him that she was the one who saved his life. Sadly, the Prince views her more like a companion or a younger sister, never considering her as a romantic partner. 5. The Tragic Choice and a Different Hope Eventually, the Prince's parents arrange for him to marry a princess from a neighboring kingdom. When the Prince meets the princess, he realizes she is the exact same woman from the temple who found him on the beach. Believing she is his true savior, he marries her. On the night of the wedding celebration aboard a ship, the mermaid awaits her death at dawn. Her sisters surface from the water, having traded their long hair to the Sea Witch for a magical dagger. They tell her that if she stabs the Prince through the heart before sunrise, she will turn back into a mermaid and live out her 300 years. The mermaid takes the dagger and enters the wedding cabin. She looks at the sleeping Prince and realizes she loves him too much to harm him. She throws the knife into the sea and casts herself into the waves as the sun rises, turning into sea foam. The Original Epilogue Andersen did not want the story to end in total darkness. Because the mermaid chose kindness over violence, she does not vanish entirely. She is lifted into the sky by "Daughters of the Air"—spiritual beings who do not have souls but can earn them by doing good deeds for 300 years. The mermaid joins them, finally given the chance to earn her own eternal soul through her own goodness, independent of the Prince.
