From the Free Port to “Invasion”: Migration, Sovereignty, and Islander Resistance in San Andrés

The 1953 creation of San Andrés as a free port marked a decisive phase in the Colombian state’s project to integrate the Caribbean Island into the nation. Framed as economic modernization, the free port accelerated demographic change, drawing internal migrants from Colombia and immigrants of Middle Eastern backgrounds who functioned, often unintentionally, as agents of nationalization. The result proved uneven and contested. While a small number of islanders experienced limited upward mobility, most faced land dispossession, rapid urbanization, political marginalization, and exclusion from the emergent commercial economy, alongside the erosion of a cultural identity rooted in Anglophone Caribbean traditions and Protestantism. Thus, this paper traces how multigenerational San Andrés islanders called “native” responded to these pressures with increasing mobilization around demands for autonomy. Drawing on newspaper articles, oral histories, ethnographic studies, literary depictions, and official state records, I argue how local actors contested and destabilized state claims to sovereignty over the archipelago. In doing so, this paper challenges Andean-centric narratives of nation-building and demonstrates how migration functioned not simply as movement or internal colonization but as a tool of territorial integration actively contested by islanders.
