Scholars often emphasize how right-wing political actors in Europe use memory laws to undermine democratic traditions and revise historical accounts. But a broad range of political actors (with diverse motivations) support memory laws. Synthesizing research in international political sociology and memory politics, this analysis examines the relational and social practices of diplomats from small states and the creative strategies of center-left political insiders in the creation and passage of memory laws. Based on data collected in the Czech Republic, the article investigates how relational and social dynamics, in part, inspired members of parliament (from the Czech Social Democratic Party) to insert Armenian Genocide recognition into memory laws about the Holocaust and Second World War in the Chamber of Deputies (2017) and the Senate (2020) – a strategy I refer to as memory fusion. In developing the framework of memory fusion, however, the findings also explore how Turkish diplomats use a similar strategy to pursue their own goals.
