The Marcha Peronista, also known as Los Muchachos Peronistas, became the musical emblem of Peronism, the Argentine political movement led by Juan Domingo Perón in the mid-twentieth century. Sung at rallies, marches and party gatherings, it came to stand for loyalty to Perón and to the movement's ideals of social justice and national pride. Short excerpts like this one now circulate online, where Argentine creators reuse the familiar opening as shorthand for Peronist identity, nostalgia or satire in short videos and memes.
