Populism has recently risen in different regions, including Europe and the United States, constituting a challenge to local and global politics. While this phenomenon existed in Europe before the Second World War (WII), the rise of the Soviet Union as a principal threat to Europe after WII prompted them to neglect populism’s negatives and emphasise confronting the Soviet challenge. After the collapse of the Soviet Union in 1991, Europe began an institutionalised process of identifying new internal and external threats, attempting to keep its capabilities mobilised for confronting challenges that might suddenly arise. This process led to identifying several internal threats, such as migration, lack of skilled employment, and populism as serious threats. Moreover, European integration began a new phase with the conclusion of the Maastricht agreement in 1992, creating the EU in its current form, which prompted Europeans to identify populism as a threat that might impede European integration.
