In 2015, the United Nations (UN) decided on 17 sustainable development goals. Goal 16 focused on peace, justice and strong institutions and on the importance of democracy for global sustainable development. This study explores the status of democracy in Europe and highlights tendencies of authoritarianism in some post-communist states. This happens in a global context of resurgence of autocratization. Although the European Union (EU) continues to be a solid liberal democratic order, challenges in post-communist Europe exist, especially in Hungary as a new authoritarian state within the EU.
