Although he also wrote novels, plays, and travelogues, Andersen is celebrated above all for his fairy tales, many of which convey deep moral and emotional truths beneath their simple surfaces. Among his most famous works are "The Little Mermaid," a poignant tale of sacrifice and longing; "The Ugly Duckling," often read as a reflection of his own struggles; "The Emperor's New Clothes," a sharp satire of vanity and hypocrisy; "The Little Match Girl," a heartbreaking story of poverty and compassion; as well as "Thumbelina," "The Snow Queen," and "The Princess and the Pea."
His stories have been translated into more than 125 languages and continue to inspire countless adaptations in film, ballet, and theater. Andersen's legacy endures as one of history's greatest storytellers, and his birthday, April 2, is celebrated worldwide as International Children's Book Day.
