This chapter analyzes Jalil Ziapour’s artistic works and the Fighting Rooster Association’s previous untranslated writings to examine Cubism in the Iranian context. Until recently, art historiography considered Ziapour’s works as belated imitations of European modernist art resulting from an artistic immaturity with regard to Western modernism. The Fighting Rooster Association (founded in 1948) and its artistic productions reveal that the first generation of modernist artists was already deeply invested in the creation of a specifically Iranian modernism. The artistic adaptation of French Cubism enabled Ziapour and the Fighting Rooster Association to elaborate a suitable visual vocabulary for the creation of an artistic subjectivity rooted in Iranian cultural heritage. In addition, it helped foster the Fighting Rooster’s political hopes and ambitions for Iran’s democratization and to proclaim an alternative national identity rooted in the country’s spiritual heritage to counter Iran’s adoption of modern Western rationality.
