This article belongs to the special cluster “Here to Stay: The Politics of History in Eastern Europe”, guest-edited by Félix Krawatzek & George Soroka. The rise of historical memory, which began in the 1970s and 1980s, has made the past an increasingly important soft-power resource. At its initial stage, the rise of memory contributed to the decay of self-congratulatory national narratives and to the formation of a “cosmopolitan” memory centered on the Holocaust and other crimes against humanity and informed by the notion of state repentance for the wrongdoings of the past. Laws criminalizing the denial of these crimes, which were adopted in “old” continental democracies in the 1980s and 1990s, were a characteristic expression of this democratic culture of memory. However, with the rise of national populism and the formation of the authoritarian or semi-authoritarian regimes in Russia, Turkey, Hungary, and Poland in the 2000s and 2010s, the politics of memory has taken a significantly different turn. National populists are remarkably persistent in whitewashing their countries’ history and using it to promote nationalist mobilization. This process has manifested itself in the formation of new types of memory laws, which shift the blame for historical injustices to other countries (the 1998 Polish, the 2000 Czech, the 2010 Lithuanian, the June 2010 Hungarian, and the 2014 Latvian statutes) and, in some cases, openly protect the memory of the perpetrators of crimes against humanity (the 2005 Turkish, the 2014 Russian, the 2015 Ukrainian, the 2006 and the 2018 Polish enactments). The article examines Russian, Polish, and Ukrainian legislation regarding the past that demonstrates the current linkage between populism and memory.
