Bella Ciao began as an Italian folk song later associated with the Italian resistance during the Second World War, and it reached a new global audience after featuring in the Spanish series Money Heist. Football supporters around the world then adopted its simple, singable melody for their own chants, rewriting the words for their clubs. The Fluminense version follows that tradition, turning the familiar tune into a Tricolor anthem heard in Brazilian stadiums and shared in fan videos, where its defiant, communal sound keeps it popular with supporters.
