This article examines international communication around moral education in the late nineteenth and early twentieth centuries, and the role of the ethical movement in facilitating this communication. Three moments of international communication are analysed. The first, in the 1890s, involves the dissemination of Felix Adler's book "The Moral Instruction of Children" among English moral educators. The second, in 1908, involves the report of a major international inquiry, and the first International Moral Education Congress in London. The third examines Frederick James Gould's tours of the USA and India between 1911 and 1914. The ethical movement's ideology and organisational structures meant it was well placed to stimulate international communication about moral education, well beyond the movement's boundaries. But it is less clear that this communication led to educational reform or sustained activity, or that there was a shared understanding--ideological or pedagogical--of moral education that crossed national borders.
