The island, the prison, and the colony: Sardinian carceral and colonial geographies.

Across research on incarceration and insularity, recent trajectories have challenged conventional understandings of islands and prisons as isolated, autonomous units. Instead, they have directed attention toward their capacity to establish relations, circuits and routes. Beyond the focus on mobility and exchanges, this literature criticised the association between insularity, incarceration and confinement as the outcome of specific colonial epistemologies. This article builds on these literatures to investigate the case of Sardinia, a large Mediterranean island that plays a key role in the Italian carceral regime by providing a destination for thousands of Italian convicts. Despite being an Italian and European region, Sardinia's past and present exhibit distinct colonial qualities, which are visible in the structure of its carceral estate. The case study exemplifies how islands can hardly be interpreted as isolated units, given that their histories and geographies have implications that extend far beyond their coasts. In the case of Sardinia, the island combines modern penitentiaries with dynamics reminiscent of previous periods in the history of punishment, specifically penal colonies and convict transportation. This case study illustrates the benefits of an interdisciplinary approach that is willing to question the conceptual categories adopted, particularly those of island, prison and colony. The article examines how research on incarceration and insularity has moved beyond previous paradigms that focused on confinement and isolation. It then applies the insights from the literature to the case study of Sardinia, a large Mediterranean island that has historically served a key role in the Italian prison system.
