The Portuguese revolution marked the closure of the country’s five-centuries of imperial history as well as its 48-year authoritarian period, a dramatic moment of political radicalization and social conflict that took place against the backdrop of rapid social transformation in an increasingly globalised world. This collection goes beyond the limits of national history to locate the revolution at the intersection of transnational historical phenomena such as the long 1960s, the Cold War, the emergence of the ‘Third World’ and postwar modernization. Foregrounding the complex geographies and chronologies of semi-peripheral Portugal, this book combines its status as the centre of a global Empire with its subaltern position in Europe. Offering a new, global, approach to this still understudied event, chapters explore transnational socialist and grassroots forms of solidarity, processes of global communication and Cultural Revolution, decolonization, feminism, and socio-economic transformations to offer a non-Eurocentric global history from within Europe itself.
