||This thesis investigates the rise in popularity of right-wing populism in Germany and France. This observable phenomenon brings a challenge to established parties in contemporary politics. On the one hand, established parties defend the principles of the European idea. On the other hand, they must necessarily engage with issues that populists have put forward as they polarize society at large. I presume that the loss of trust into the European idea has become more substantial with the arrival of refugees in 2015, thus adding more constrains on policies proposals of established parties. However, the refugee influx has become the trigger mechanism that made populist sentiments more acceptable in society. To understand this rise of populism, I propose three conditions as possible explanations; cultural resentments, victims of modernization and economic grievances.
