Bella Ciao began as an Italian folk song later adopted by anti-fascist partisans in Italy during the Second World War, long before it reached television. It became a worldwide anthem again when La Casa de Papel, known in English as Money Heist, used it as the crew's rallying song, with the series reaching a global audience through Netflix from 2017 onward. The melody spread through covers, protests, football chants and social media edits, and it remains a shorthand for resistance, teamwork and a daring comeback.
