The field of Global Politics has largely overlooked the concept of solidarity. In an attempt to invoke the theoretical significance of this nebulous idea, the study explored the meanings and scales of political solidarity articulated by the Swedish Social Democratic Party (SAP). Drawing on interdisciplinary research, the Swedish Socialist Democratic Party’s articulations of solidarity in immigration policy stances, party programs, and first of May speeches were explored through an interpretive tradition. By mapping the progressive enlargement of SAP’s conception of solidarity in manifestations concerning global migration the continuity and changes to its various meanings and scales were displayed. Over the last fifty years, SAP’s conception of solidarity has largely configured in stability. Solidarity entailed the ones with whom we may have nothing in common but our humanity and the immigration entry-policy developments between 1970 and 2020 included minor steps toward openness but were restrictive for the most part. This engagement in the broader debate about open borders demonstrated solidarity’s vulnerability to the vicissitudes of history. Manifestations of solidarity by the current SAP government maintain an elusive terrain. Solidarity was the objective of the Swedish asylum policy but the absence of solidarity within the common European framework triggered an end to Swedish exceptionalism in terms of respect for and protection of human rights.
