"Snow White" is a fairy tale known from many countries in Europe, the best known version being the German one collected by the Brothers Grimm (German: Schneewittchen und die sieben Zwerge, "Snow White and the Seven Dwarves"). The German version features elements such as the magic mirror, the poisoned apple, the glass coffin, and the seven dwarves, who were first given individual names in the 1912 Broadway play Snow White and the Seven Dwarfs and then given different names in Disney's 1937 film Snow White and the Seven Dwarfs. The Grimm story, which is commonly referred to as "Snow White", should not be confused with the story of "Snow White and Rose Red", another fairy tale collected by the Brothers Grimm.
In the Aarne-Thompson folklore classification, tales of this kind are grouped together as type 709, Snow White. Others of this kind include Bella Venezia, Myrsina, Nourie Hadig, The Young Slave and Gold-Tree and Silver-Tree.
