Violence against women politicians is increasingly recognized as an issue that undermines women's presence in politics. Latin America has been at the vanguard of this global discussion. In 2012, Bolivia became the only country in the world to criminalize “political violence and harassment against women.” Several other countries have similar legislation in the works. What explains the emergence of these bill proposals? This article argues that the creation of these bills is the result of three processes: activism at the local level used international norms to propose an innovative solution to a problem; women politicians and “femocrats” worked within the state apparatus to overcome resistance; and international actors worked to foster connections among activists and politicians across the region. In this process, international norms have been transformed, with important implications for women's political representation.
