This chapter explores the evolution of resistance movements against military land occupation in Sardinia, tracing their roots and impacts over decades. It examines diverse forms of grassroots mobilization, from the nonviolent protests in Orgosolo’s Pratobello in 1969 to contemporary assemblies like A Foras, formed in 2016 to oppose military bases and advocate for environmental justice, decontamination, and local autonomy. These movements, driven by collective learning and intergenerational collaboration, illustrate the resilience and adaptability of Sardinian communities in asserting territorial sovereignty. Key case studies include the Pratobello uprising, opposition to national park projects perceived as tools of colonial environmentalism, and resistance to US nuclear bases on La Maddalena. Through ethnographic data and historical analysis, the chapter highlights the interplay between local and global resistance frameworks, connecting Sardinia’s struggles to broader anti-colonial and antimilitarization efforts. It also addresses the role of gender, cultural identity, and environmental justice in shaping the dynamics of these movements. By situating Sardinia’s resistance within wider discourses of autonomy, environmental sustainability, and social justice, this chapter underscores the enduring tensions between militarization, economic interests, and community rights, offering a nuanced understanding of the region’s socio-political landscape.
