This book deals with the broader theoretical and philosophical context of performance art in former Yugoslavia, focusing on more than three decades of politically engaged performance activity of the Montažstroj group. Their activity is only a starting point for a deeper analysis of some of the key notions of contemporary “art-ivism” in a much broader post-political and globalized context before, during, and after Yugoslavia and its Socialist paradigm collapsed. The author analyzes and sets notions of agonism, engagement, terrorism, post-war trauma, political populism, social Darwinism, participation and publicness, and the public sphere into different theoretical matrixes.
