Abstract
With the rise of populist regime and its implicative tendencies around the world, we need to understand that institutional delegitimization is on the rise. The third pillar of democracy, i.e. the executive, has steadily shown a dualistic reaction of reconciliation and antagonism alongside systematic changes in perception about populism. The case studies on the populism are a preliminary analysis of the political conditions which give rise to populist leaders and their regime, it actually hints at the tumultuous conditions which are brought from its inceptions like in cases of Central European, Asian and Latin American countries.
