We define tribalism as a mode of articulation that draws an antagonistic frontier between societal groups. Unlike populism, tribalism does not have a hegemonic character. It articulates groups through a horizontally oriented shared value system; whereas populism is an essential part of a democratic system, tribalism disregards democracy. To conceptualize tribalism as a separate theoretical frame from populism or (ethno)nationalism, we used discourse theoretical analysis to analyze the Facebook pages of four political party leaders in Slovakia (Marian Kotleba, Krisztián Forró, Igor Matovic, and Boris Kollár). Kotleba’s page showed tribalistic features by articulating an antagonistic divide between “us,” the people, linked by shared values and identities, and anyone who does not share those values, or “them.” His representation of his party’s fight against oppressive forces combined with their apathetic stance toward democracy makes them a prime example of a tribalist party. While populism is an ever-expanding area of research and a framework widely used to analyze political entities and events, it is a word often thrown around and thus overused. Tribalism offers an alternative approach to analyze political instances in a national and transnational context in a more nuanced way and gain a better understanding of previously overlooked phenomena.
