The COVID-19 pandemic has impacted politics, both international and domestic, by affecting the governing and political systems of multiple countries, causing suspensions of legislative activities, isolation or deaths of multiple politicians and reschedulings of elections due to fears of spreading the virus. The pandemic has triggered broader debates about political issues such as the relative advantages of democracy and autocracy, how states respond to crises, politicization of beliefs about the virus, and the adequacy of existing frameworks of international cooperation. Additionally, the pandemic has, in some cases, posed several challenges to democracy, leading to it being undermined and damaged.
