Is sisterhood global? This study investigates if women in Congress are representing women worldwide by extending their surrogate representation of American women to women in foreign countries. Congressional research shows that race affects surrogate representation across borders via transnationalism. I test whether this also applies to gender when no shared "mother country" unites women, there are divisions over how to represent women, and American foreign policy is considered a stereotypically masculine policy domain. With an original dataset of three Congresses (2005–2010), I test if female House Representatives are more likely to introduce foreign policy legislation that targets foreign women and girls by applying regression analysis. Controlling for likely individual, electoral, and institutional incentives, I find that gender matters and that women in Congress are more likely to introduce legislation on behalf of women worldwide, acting as global surrogates. These findings offer new insights into the boundaries of surrogate representation, congressional foreign policy decision making, the influence of gender on international relations, and the impact of women in Congress.
