Two decades ago, we were still reflecting on the "democratization of democracy". Times have changed. Now we are thinking about the resilience of democracy. Times are changing. The long and global trend of democratization, which accelerated once again after 1990, reached its peak in 2008. Since then, liberal democracies are now in the 15th year of a continuous and significant decline. This is true even for the best constitutional liberal democracies of the Northern hemisphere. An extraordinary simultaneous accumulation of external crises has challenged democracy in the last 15 years: financial and euro crises, migration and refugee crises, climate crisis, pandemic and finally the Russian war against Ukraine and its economic repercussions on Western democracies. How can democracies arm themselves against this, how do they strengthen their resilience? What actually is resilience of democracy? Do we have sufficient theoretically inspired concepts that we can use in empirical studies? The Talk aims to present such an analytical concept of democratic resilience in order to finally answer the action-theoretical question: How can democracies strengthen their resilience in the current decade of crisis?
