 In 1917 Montessori published her elementary work in "L'autoeducazionne nelle Scuole Elementari (Self-Education in Elementary School)", which appeared in English as "The Advanced Montessori Method".Around 1920, the Catalan independence movement began to demand that Montessori take a political stand and make a public statement favoring Catalan independence, and she refused.Official support was withdrawn from her programs.
