The planned language Esperanto achieved popularity in early twentieth century Japan, inspiring a national movement which was the largest outside Europe. Esperanto was designed to facilitate greater international and inter-cultural communication and understanding; the history of the language in Japan reveals a rich tradition of internationalism in Japan, stretching from the beginnings of the movement, in the wake of the Russo-Japanese war, through the end of the Pacific war, when, for a brief period, organised Esperanto in Japan ceased. Building upon existing studies of internationalism amongst elite opinion makers in Japan, this history of Esperanto reveals unexpected examples of internationalism amongst the broader Japanese public, a number of competing conceptions of the international world, and their realisation through a range of transnational activities. Esperanto was at once an intellectual phenomenon, and a language which could be put into immediate and concrete practice. The diversity of social groups and intellectual positions within the Japanese Esperanto community reveals internationalism and cosmopolitanism, not as well defined, static concepts, but as broad spaces in which different ideas of the world and the community of mankind could be debated. What linked the various different groups and individuals drawn into the Japanese Esperanto movement was a shared desire to make contact with, and help to reform, the world beyond Japan's borders, as well as a shared realisation of the vital role of language in making this contact possible. From radical socialists to conservative academics, and from Japanese diplomats at the League of Nations to members of rural communities in the deep north of Japan, although their politics often differed, Japanese Esperantists came together to participate in the re-imagining of the modern world; in doing so they became part of a transnational community, one which reveals insights into both modern Japanese history, and the nature of internationalism.

This dissertation demonstrates that a group of western women connected to May Maxwell through ties of faith and friendship exemplified a distinct form of early twentieth-century feminism in their adoption and promotion of the transplanted Bahá’í Faith. In actualizing their doctrinal principles, they worked to inaugurate a millennial new World Order predicated on the spiritual and social equality of women. This group championed a unique organizational structure and transnational perspective that propelled them to female leadership, both as inspirational models and agents of practical change. By examining how Bahá’í doctrines shaped the beliefs, mythologies, relationships and reform goals of women, this dissertation broadens understandings of the ways in which religion can act as a vehicle for female empowerment and transformative identity. Together, western early Bahá’í women built individual and collective capacity, challenging gender prescriptions and social norms. Their millennial worldview advocated a key role for women in shaping nascent Bahá’í culture, and initiating personal, institutional, and societal change. Their inclusive collaborative organizational style, non-western origins and leadership, diverse membership, and global locus of activity, made them one of the first groups to establish and sustain a transnational feminist reform network. Although in some respects this group resembled other religious, feminist, and reform-oriented women, identifiably “Bahá’í” features of their ideology, methodologies, and reform activities made them distinctive. This research contributes to a more nuanced understanding of the role of women in the creation of modern religious and social mythologies and paradigms. A study of Bahá’í millennial religious feminism also expands current conceptions of the boundaries, diversities, and intersections of early twentieth-century western millennial, feminist, religious, and transnational reform movements.
