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.
