The influence of these books was widespread. W. H. Auden praised the collection, during World War II, as one of the founding works of Western culture. The tales themselves have been put to many uses. Hitler praised them as folkish tales showing children with sound racial instincts seeking racially pure marriage partners, and so strongly that the Allied forces warned against them; for instance, Cinderella with the heroine as racially pure, the stepmother as an alien, and the prince with an unspoiled instinct being able to distinguish. Writers who have written about the Holocaust have combined the tales with their memoirs, as Jane Yolen in her Briar Rose.
The work of the Brothers Grimm influenced other collectors, both inspiring them to collect tales and leading them to similarly believe, in a spirit of romantic nationalism, that the fairy tales of a country were particularly representative of it, to the neglect of cross-cultural influence. Among those influenced were the Russian Alexander Afanasyev, the Norwegians Peter Christen Asbjørnsen and Jørgen Moe, the English Joseph Jacobs, and Jeremiah Curtin, an American who collected Irish tales. There was not always a pleased reaction to their collection. Joseph Jacobs was in part inspired by his complaint that English children did not read English fairy tales; in his own words, "What Perrault began, the Grimms completed".
Three individual works of Wilhelm Grimm include Altdänische Heldenlieder, Balladen und Märchen ('Old Danish Heroic Songs, Ballads, and Folktales') in 1811, Über deutsche Runen ('On German Runes') in 1821, and Die deutsche Heldensage ('The German Heroic Saga') in 1829.
