The COVID-19 pandemic is considered one of the biggest crises that countries in Europe have experienced since the Second World War. It is precisely in times of crisis that populist parties grow. The aim of our article is to find out how Slovak left-wing and right-wing populists communicated in the period of the COVID-19 pandemic. We are interested in what topics the populists emphasized as their priorities and what means of expression they used in communicating with their voters. We thus approach radical populism as a mode of political communication. A number of authors define populism as a simplistic style of communication that reduces complex political issues to the responsibility of 'guilty parties' and political competition to the opposition of friend and foe. Thus, the question remains who was the enemy of Slovak radical populists in the period under study.
