Democracies around the world are currently threatened by a danger that is not new to the political landscape of history. Political and emotional polarisation is a phenomenon that has affected humanity ever since it organised itself into complex political systems. However, what is new today is the factor that triggers polarisation. Although populism itself is a relatively new phenomenon, the media sophistication it has achieved today allows it to alter democratic systems from their foundations. This poses new regulatory challenges to mitigate its causes and thus guarantee popular sovereignty. This research aims to analyse Spanish populism today and its influence on the polarisation of the country. The study seeks to identify the factors that cause its increase or decrease, with the ultimate goal of controlling it. To this end, a qualitative methodology combining doctrinal studies and political practice will be used. Throughout this analysis, it is important to bear in mind that polarisation is not merely a temporary issue of unrest; its causes are much deeper and more complex, requiring a much more detailed approach.
