Ultraconservative nationalism is on the rise. We can quickly see it by mentioning a few names: Trump, Orbán, Milei... It is in this context that historian Eric Storm (Netherlands, 1966) published Nationalisms, a world history (Crítica), a book that doesn't focus on a single country or continent, but rather, as its name suggests, examines the history of nationalism worldwide in an exhaustive work that allows us to draw the similarities that exist between regions and understand why it is advancing worldwide.
