This seminar will discuss different types of contemporary regimes both in the West and in the Muslim world: democratic, authoritarian and the emerging category of hybrid regimes. It will provide an overview of the dynamics of transitions to democracy and the authoritarian backlash. On the basis of case studies (US and Pakistani elections, Brexit), we will critically discuss the concepts of populism, radicalization or Euroscepticism. In the Western European context, we will analyse the development of radical political parties on the right (e.g. Alternative for Germany, Rassemblement National) and on the left (Podemos). In Central and Eastern Europe, we will discuss the 'conservative revolution' announced and implemented by FIDESZ in Hungary (since 2010) and Law and Justice (PiS) in Poland (2015-2023). In the Arab and Muslim world, we will explore the complex processes of democratization in the Arab Spring, in the framework of the War on Terror (Afghanistan and Iraq), as well as the hybrid case of Pakistan’s regime. We will also compare two of the most peculiar parties of the Middle East, which both are complex entities: Hamas and Hezbollah.
