In this thesis I explore the global circulation and cross-cultural encounters of women advocacy travelers in the early twentieth century. I focus on Carrie Chapman Catt, Margaret Hodge, Mildred McFaden, and Madeleine Z. Doty, who journeyed around the world in order to advocate for women’s rights and peace. Catt traveled on behalf of the International Woman Suffrage Alliance (IWSA) to South Africa, the Middle East, and Asia in 1911-12, Hodge promoted women’s suffrage around the British dominions, and McFaden and other members of the American Woman’s Republic brought a resolution linking peace and women’s suffrage to the IWSA congress in Budapest in 1913. Doty made several journeys from the U.S. to Germany and Russia, as a dissident antiwar journalist during the First World War. Using their travel writings, I explore these women travelers, their encounters with women from other countries and cultures, and their ideas about internationalism and inclusion in the worldwide movement for women’s rights.
