This article examines multi-vector pro-life exchanges between Poland and two American countries: the United States and Chile. We make the case that the 1970s through 1990s represent a significant historical moment that yielded both transplantable templates and direct longitudinal consequences for transnational social activism in the twenty-first century. We argue that during this time Poland acted as an incubation site for pro-life transnationalism, where “right to life” became the rallying cry of new generations of Catholic Far Right thinkers and activists like the politician Marek Jurek and journalists and social activists Ewa Kowalewska and Lech Kowalewski. The transnational entanglements that empowered Jurek, Kowalewska, and Kowalewski assumed intellectual and political forms, while also producing direct contact and active exchange of tactics, ideas, and know-how with the leaders of the U.S. pro-life movement such as John Willke or Father Paul Marx. Our study, situated at the intersection of intellectual history and social movement studies, highlights the importance of examining transnationalism with full attention to its local rootedness, and makes a case for incorporating non-progressive social activism into the post-1989 story of civic and social mobilization.
