The nationalist phenomenon has played an important role in contemporary history. We are currently entering the fourth industrial revolution, a process of social and political change driven by artificial intelligence, 5G connectivity and other cutting-edge technologies. This paper explores the manifestation of nationalism in the fourth industrial revolution, in particular the concepts of techno-nationalism and digital nationalism, their relationship and their differences. Subsequently, the article explains how digital media affect the rise of techno-nationalism and offers a broader definition of the (...) concept, including the ideas of digital territory, digital culture and digital identity. The article concludes that techno-nationalism is a complex manifestation of nationalism that includes not only a country’s quest for technological sovereignty, but also has an ideological component strongly linked to the political use of cutting-edge technologies.
