This lecture recasts the U.S. suffrage movement through an international lens. It explores how U.S. suffrage advocates collaborated with other activists across national borders and were often themselves from other countries. It demonstrates the importance of international organizations, conferences, and publications that in turn spread information, ideas, and strategies. It also underscores how the shifting position of the U.S. in the world from the 19th to 20th centuries, influenced suffrage activism. Casting new light on some familiar figures and bringing less well-known ones to life, this talk underscores that the U.S. suffrage movement relied on transnational support in order to thrive.
