Pippi Longstocking (Swedish Pippi L√•ngstrump) is the protagonist in the eponymous series of children’s books by Swedish author Astrid Lindgren. Pippi was named by Lindgren’s then nine-year-old daughter, Karin, who requested a get-well story from her mother one day when she was home sick from school.

Nine-year-old Pippi is unconventional, assertive, and has superhuman strength, being able to lift her horse one-handed. She is playful and unpredictable. She frequently makes fun of unreasonable adult attitudes, especially when displayed by pompous and condescending adults. Pippi’s anger is reserved for the most extreme cases, such as when a man ill-treats his horse. In a Peter Pan-like vein, Pippi does not want to grow up. She is the daughter of a buccaneer captain and as such has adventurous stories to tell. She has four best friends: two animals (her horse and monkey) and two humans (the neighbour’s children Tommy and Annika).
