Constructing Proletarian Nation(s): PSOE Internationalism in the Second Republic (1931–1932)

Abstract This article seeks to enhance our understanding of the nature of socialist internationalism, in particular by considering the place of the nation in its functioning and essence. For this purpose, the concept of inter-nationalism is used to study the particular case of the Partido Socialista Obrero Español (PSOE) during Spain's Second Republic. In the first section, we focus on the meeting of the executive of the International Federation of Trade Unions (IFTU) in Madrid in 1931, and the subsequent May Day celebrations in the city. In the second, we analyse the use of internationalism by the PSOE in the debates on the decentralization of the Republican state. This article will argue that the PSOE made use of internationalist events to further the internal and external consolidation of the Republic, and its own position in government. Furthermore, internationalism served to uphold the unity and unique qualities of Spanish politics and culture. These considerations enable us to point to both the political and cultural dimensions of the PSOE's identification with Spanish nationalism, and to assert both the nation's importance in socialist internationalism and its role in socialist political culture during the interwar period.
