The COVID-19 pandemic dominated European politics through 2020. At the moment，Europe is still shrouded by the pandemic，with increasing number of deaths. The pandemic serves as a magnifier，thereby allowing us to investigate European politics and European integration more clearly. It also acts as an accelerator，which intensifies the trends of European politics. COVID-19 has further weakened European governance capability and governance system. The leaky public health governance system，limited governance effectiveness，and insufficient governance capability exacerbated existing challenges in European politics. Moreover，the pandemic has reshaped the European political agenda，prioritized pandemic-related issues，and further led to European differentiated integration. However，the pandemic could not fundamentally alter the European political landscape.
