Between 1900 and 1914, the British and American suffrage movements were characterized by interaction among suffragists, their organizations, and their publications on a much broader scale than has been generally recognized or acknowledged. This study isolates and examines the various connecting links ranging from personal relationships to the emphasis on a common cause. Women participated in one another's organizations and activities, including speaking tours and visits, and each group used the experience of the other to stimulate its own progress. In addition to the prominent figures of the day, Harrison includes information about lesser-known suffragists whose names and actions have been largely lost to history.

The interaction between the British and American movements began in the 1870s when a network of suffrage friendships and relationships started to take shape, and cooperation escalated in the last two decades of the century. Connections expanded and peaked between 1900 and 1914, but, with the outbreak of war in August 1914, the extensive interaction came to an abrupt end. Harrison provides a history and comparison of the two movements to give the reader context and a background against which to study the international suffrage campaign. She assesses correspondence, diaries, journals, memoirs, pamphlets, articles, and coverage within the suffrage press itself.
